All other options from Text Sensor. Everything ist working fine so far when it comes to numbered variables such as solar power (W) etc. I can read forecast by http_request. What I want to to do is basically: Hi, I have been using this guide to help keep a device awake for updates: I seem to have a problem that the device doesn’t reliably get the value from HASS (it does sometimes) and am really struggling to troubleshoot. Right now I’m primarily dealing with numbers and text and I can’t find clear examples of how to compare one number to another, to use them in Hello, I am trying to save input from an mqtt topic to a global variable, so I can use it later. This code works good with esp. Can I convert from these formats to variables in esphome, or do I need to do it in C++ I’ve read through this quite a bit and tried a bunch of schtuff: I’m looking for a very simple code sample – no interactivity, just variables, really – of how one would take a state (let’s say, “outside temperature”) in Home Assistant and send it through to an ESPhome variable where it could then be printf’d to a display. I have set up a sensor to capture the reference thank you, you are probably right. I can’t for the life of me figure out how to do this. Now am trying to display the current brightness 🔆 level on the display using the lambda function. The value I get is between 0-1, e. Media player volume slider¶. But it requires a either a float or a string where I’d like to use an integer. Deleting my post. I was thinking about global variables, but I can not understand how to implement it using HA. This can be used as name for the device, but it can also be used as pre-fix for the ESPHome entities. The entity state is used when this option is omitted.

Ah yes, misunderstood the question. When nobody’s consuming I’m using an ultrasonic sensor to measure water tank level. Hello Mattias, as I am still at the beginning with ESPHOME and practising, I have tried to proceed in small steps! Task: when the temperature goes above 26°C, a “time” should start → the time is stored in the variable “my_globel_int” and can be changed if necessary via “HomeAssistant”. In ESPHOME I would create the homeassistant component which would read the value of the sensor. 0 and ESPHome to 2021. I Hi!! I wish to have a sensor publish High resolution data when within a certain value set, and revert to a more manageable update rate the rest of the time. Right now I’m studying this thread on the forum, from back in April. I’m really beating my head over how to do this. I’ve tried setting the target sensor up as a platform: homeassistant sensor and reading it back from there but I always get back a Not the faux global variables implemented by various custom components but first-class citizens of Home Assistant. What I want to be able to do is print a state from a sensor from Home Assistant. Homeassistant has an id called “esptime” . h. Thanks for the help! Hey community, I want to control a heating element through a PWM to voltage converter (0 to 10V). From what I understand this would require using either a global variable or reading the value from HA and neither is allowed for a calibrate linear filter. I would create the input number component in home assistant, then would apply the value of it to the sensro. It is so easy to use a sensor with platform DHT for example to show temperature in HA why no having a platform for global variables I want to show some internal values I do calculation with in Home Assistant. If I move the printf outside of the if statement so it always gets Reading the docu on esphome. See both at: “Display Component — ESPHome” You COULD pre build your string for it. Purpose in brief: I’m running a stepper motor with Home Assistant automation and I want to save the value of the stepper motor position (integer) in ESP32 so in case of lost connection etc. I’m trying to create an rf433 rc switch, which works with different codes. It’s connected to a nodemcu and it’s working and I can print simple text to it no problems. I’ve created a pulse sensor with a total, and created a second template sensor that is also going to act as a total - the difference between the two is that they show different values as have different calculations applied to them. Since I Hi, I am building an EPaper-Display with ESP32 board. 3 v to 200 Ohm resistor. I want to have the hysteresis as variable that I can easily access within my code. I am using a potentiometer with adc on the esp, I get the value in HA as a sensor, this works fine. I got that problem and I know how to used !secret.

The boards all have wifi chips with mac addresses that have the last 6 characters that are unique. Hi, Soon i’m planning to build a garden irrigation system with ESPHome, and therefor will trigger a few relays which in turn will control solenoid valves to enable/disable my garden sprinklers. Everything works fine but I can’t save the steps value on flash memory of esp32 (in order to survive power loss). However, I wish I can just get ESPHOME to output it without having to mess with Home Assistant Templating. 7. I’m a bit stuck with my first ever ESPHome project and looking for a little guidance please. on_value: then: - sensor. casa attribute: forecast The imported sensor result “unavaible”. Supported domains¶. I found it by accident, but I cannot find it documented anywhere, and I wonder what other homeassistant ids are available. I tried using lambda’s but it won’t pass compilation. to make ESPHome automatically use the last value it reported to Home Assistant after a reboot as a new base value. I see I want to calibrate it using home assistant. Note that I am not using HA. Similarly, you can use a slider or an Hi i am stucked importing forecast states in esphome. I would like to make esphome sensor independent on Home Assistant in that it reads weather forecast from openweathermap and controls some switches (roolls up exterior blinds if wind is coming). set_valve_position, too; the only difference is that max_value has to be 100.

Home Assistant Community Esphome & nextion tft lcd. set_speed” action does not seem to work properly. I measure the volt level from the sensor and each cm equals 4. You can also define a “id” for sensors in the ESPHome yaml file, which can be used internally in the ESPHome code. So I’d suggest creating a small automation / lambda that on a regular basis writes the home assistant value to a global Instructions for setting up Home Assistant sensors with ESPHome that import states from your Home Assistant instance. scorbot_command. To get an accurate reading I have to define the reference voltage as a configuration variable. You can calculate the linear equation y = mx + c from the following:. I would like to have some reusable functions that I can call in lambda’s. Hi, I am trying to take a reading from a temp sensor and display it on an oled, I can read the sensor and display simple text on the display but when I try and display the variable I get errors, I’m new to this and I’m sure I’m missing somethinf simple. DrewW: does not appear to add the needed input. Currently, only the ESPHome tool, Home Assistant and ioBroker use this native API. Prior to the update, my yaml files for a NodeMCU would compile fine with substitutions used in a variable name for a secret. It has an analog pressure Sensor fed through am ads1115 ADC, and a pulse flow meter fed through the pulse counter component. Thanks!

The only variables there are ESP32 vs. So let’s say the water heater goes up to 60⁰C, and it’s a hot day so I set the target temperature to Configuration variables; See Also; Join the community; Follow us on Twitter; Source Code; The preferred way to get time in ESPHome is using Home Assistant. I’ve flashed smart outlet with ESPHome using HLW8012 I am trying to make a dosing system. I followed the example from the stepper documentation, and the stepper motor works fine with the “stepper. Any help would be appreciated, please and thanks. My thinking is to: Create an input_number in HA. Instructions for setting up the native ESPHome API for communication with Home Assistant. It’s Hello Board, i wanted to control color of single rgb LED (2812) for which im currently using following code, id(LED0). print but that’d probably be, uh, crazy loco. See: ESPHome Core Configuration variables. As you can see in the code below, Use Global Variables with script in ESPHome. mascatul (Sadi) July 11, 2020, 1 How to pass a variable from Home Assistant to ESPHome custom component? postlund (Pierre Ståhl) March 11, 2021, 1:33pm 2. 0. I am trying to control a thermostat knob with esphome stepper motor. Is there a way to fix this? It is used for ESP deep sleep. So I’ve created a global variable of type string like this: globals: - id: emoncms_api_key type: std::string restore_value: no initial_value: !secret my_variable my_variable is defined as"123fadk99kjdfa789" in secrets. With the homeassistant time platform, the native API connection to Home Assistant will be I am setting up a small OLED screen, and I want to show current time, and some weather conditions like current weather, wind force and temperature. peted (peter) June 29, 2022, 3:46pm 3. The challenge is that the voltage fluctuates by 0. 5°C heat_output: gasklep control_parameters: kp: !lambda: The bolded 53. 5” Now - how do I read/update this value from the custom components header file ? And is it possible to change the value from the custom component ? This is with a float As Hello, as mentioned in the 2023. Sent From Home Assistant to ESPHome: sensor: - platform: homeassistant name: "feed molly" entity_id: sensor. I want to use the value/state of this helper in ESPHome in a while section of a binary sensor: - while: condition: - binary_sensor. This is the esphome yaml that produce the sensor if I just tried to set up a resistance sensor with ESPHome and I only get background noise with it. net. I’m using the Sprinkler Controller and it’s working great. It looks like I have to set up a substitution, like this: substitutions: VentFanDelay: 120 #delay in seconds And then, later, I use it by typing: ${VentFanDelay} Is Hi If I have a number of global variables (floats), and an associated service has been created for each of them (to make them settable from HA) - if there a way to check the value passed from HA - in order to validate the value ? For example, if I need to set up 4 intervals, I specify 3 thresholds: x < threshold1 x >= threshold1 and x < threshold2 x >= threshold2 and x Hi all, Still very new to ESPHome and finding it a very steep learning curve. So I’ve set up the pulse_meter sensor to read out my gas meter and I’m trying to figure out how I can persist the total number of pulses between reboots / updates, since the total value returned by the sensor resets to 0 when I update the esp. You would use a lambda to write the value to the global when it changes (using on_value: ). m = (7. I’m new to ESPHome. yr_symbol_current I was hoping printf with the parameter %s would work, but unfortunately not. Home Assistant Community String as global variable. I’ve gone through a few YAML tutorials and see them using key/value pairs to set variables, but that doesn’t work in the config for ESPHome. set_target” action. When the bell is switched off, only the Create a global variable; Turn on restore from flash in the ESP8266 config; When you get a valid value for your set point from HA, store it in that global variable; On restart - until the value from the HA sensor is updated, I have a helper called P5 defined in home assistant. I'd like to publish a boolean variable that I've calculated in a lambda to Home Assistant so I can use Configuration variables: id (Required, ID): Give the global variable an ID so that you can refer to it later in lambdas. 1. Changing these will be much faster and more user friendly if I could pass a value from a HA slider to a global variable in ESPHome. Components do not have a string name representation. I have a home assistant input number that I’d like to use in delay functions. Theoretically, it’s simple. Is there a way to do this? Ideally a way that I can use to send the setpoint from Nodered. If you want to do this you will have to create a Lambda Filter that implements the linear transform. (I will later use this data to control a motorized fader!) Here is the yaml for my esphome node. I check the “timestamp” on the first edge and subtract it from the “timestamp” on the next one. is_on: p5 then: - logger. I obtain the value from home assistant as follows: sensor: - platform: The generic version of my question is how can I use the Home Assistant area as a variable within an ESPHome config, such that if I change the ESPHome device area within HA the functionality changes? I want to use the area of the esphome device in a service call to home assistant. tomesp December 21, 2019, 1:34pm 1. Click the “configure” button next to it. . perform(); The rgb values are assigned in global variables in the code, hence when above line of code executes the Thanks Edwin I have been looking at that project too. However, we would also want this to trigger when I want to send a brightness data of a lamp from HomeAssistant to my ESP32. In another room there should also be an ESP8266-01s which switches on/off the boolian value in the HA by pressing a button. All is working fine when someone rings the bell: the standard house bell rings (used a relay on the D1 mini) notifications are sent to my television and different iPhones together with live-stream video from my camera google home The only way you can currently edit and save an arbitrary string on ESPHome is to link a Home Assistant text sensor to an input_text: helper in HA, and edit the text on HA. It can control a switch to turn the pump on and off, but my pump isn’t connected to this device, but it’s on Home Assistant. state}}" I’m trying to get some help over on Discord with issues with escape sequences. Hello! I’m having difficulties with global variables (I need to save the variable value over boots) and how to read them in Home Assistant. yoghurtmaker’ and I need to pull the temperature value that is set in the dashboard. I’ve tried the obvious places, but I get the impression that the ESPHome documentation is a work in progress. At one point (in the 2nd post on the thread), @ckxsmart states there is no string representation of components, so what I want to do may be impossible. Somehow, it looks like, it’s not possible directly. I currently use this to read data from my heat pump. I was doing calibration (power and voltage measurement) and I setup update_interval to 5s to see changes more often. execute: consider_deep_sleep # prevent deep sleep I am in a little above my head and hope someone can nudge me in the right direction. It looks like variables are not accepted in entity_id. attribute (Optional, string): The name of the state attribute to import from the specified entity. - platform: integration name: "Battery SOC" id: battery_soc sensor: wattage_calculated integration_method: "left" time_unit: h restore: true device_class: energy filters: - clamp: max_value: 640 Thanks guys, with a bit of tweaking I got it working! Only thing is my servo keep on spinning now and it does not stop? ESPCONFIG. mascatul (Sadi) July 10, 2020, 12:43pm 1. Is there a way to define global varriables inside a lambda? And, is there a way to write/read data directly to the flash? I ask these questions because I am planning to program a light control for my aquarium. 0)/(ph7_value - ph4_value) c = 7. As I see it I need a variable in my automation that I can modify from the outside. Sadly my HA box Hi, I would like to use a variable or input field the define the value for a filter. First problem is the right way to define the string (char[] or String?), second problem is to store a value from a textsensor-state into my global. esphome. Offcourse, this would be very easy to do in HomeAssistant by first sending the Hi all together, since the ESPHome and HA support new entities and components with the new update, I’m especially interested in ESPHome’s number component. Drew. team_tracker_browns attribute: team_id I think I have that part right. There is an “arduino nano”, it sends data from different sensors via uart to esp-01s 433-esp01-uart. I have tried multiple variants without succeeding. The entity id referred to in the sensor definition must already exist in Hi guys, Pretty new to ESPHome and need some help from the gurus out there 😊 I’ve a D1 mini on ESPHome used for my frontdoor bell. @ssieb has been a real gem here, and used a LOT of time on me, thankyou very very much, and he got everything working. Automation While I’ve programmed in a number of different languages, from low level like Assembler, to higher level like Python or Java, I’m having serious difficulty understanding how to use variables in YAML files on ESPHome. 3v. I have a global prevent deep sleep toggle and device specific ones. (of course I have to stop Template Button 1 again, but I don’t want to put too much problems into this topic now ^^) What my problems are: The delay seems to How can i restore a value from home assistant after a reboot or reprogramming. test value_template: '10' The I got the id from home assistant and defined a sensor in esphome in this way: api: # MQTT mqtt: broker: 192. I was able to create a binary string for esphome, but i cant figure out how to send id. So, if you want to execute a function on a component based I (mostly) get how you can create a custom sensor so you can display the current value of something from ESPHome to Home Assistant, but what if I want to write back to a variable for use in a lambda? For example, when calculating a flow rate I need to count the number of cycles equal to one cubic foot. The following entity domains from Home Assistant are supported by this platform. 16. I am using it. My aim is to have an esphome. A helper, in this case called input_text. You can use this variable in lamda however you like. printf (formatted text) which is designed to do allow much more. 1 Like. When clicking on the sensor entities it used to show the graph for power, energy usage, etc. I’d like to compare the two values so when they match, the motor is turned off. Curious what your use case is (something to do with different timers;), and syntax for accessing individual values of the array in a lambda (I assume it is something similar to timers[3][3]?) While I can personally use a deep_sleep mode myself, I’m currently breaking my head over the following process: Receiving a MQTT value Store the MQTT value in a global int <---- Recall the int, and apply to the deep_sleep_duration I think I’m doing something wrong storing the MQTT value in the global int. Check the “Allow the device to perform Home Assistant actions” box So I have one of those 16x2 LCD Displays. This is applicable to action calls like fan. What I’m trying to do is (within ESPHome) turn on a GPIO at a repeatable interval where the interval is configurable via a home assistant input number. turn_on(). Unfortunately there seems to be a problem with encoding. We should be able to define a global string, integer, float, list, dict. Even the initial value does not work services: - service: send_upcomingevents variables: thelist: string[] #thelist: std::vector<std::string> #fails compile then: - logger. By default a ESPHome sensor will lose it’s value after a power down and start again at 0. So this is in the pulse sensor declaration. I’d like to use it on the “range_to” line: binary_sensor: - platform: I’d like to be able to set a variable / number on the web_server webpage, have it persist during reboots, and use that number in some calculations. I would like to set a fixed speed for the stepper motor, but the “stepper. 2 esphome changelog, ESPHome now supports setting a friendly_name which is sent to Home Assistant. sleeptime id: sleeptime to check the value I’m wondering if it’s possible to hook an ESP home device equipped with a potentiometer to control devices like light dimming, fan speed, thermostats, speaker volume, and other devices that might take variable Basically the advice in the ESPHome documents on using the Home Assistant secrets file don’t seem to work. g 70% brightness is displayed as 0. ESPHome. Unfortunately, I was not even able to work with variables within ESPHome. eg like this: service: esphome. Hi, I’m in the process of learning ESPhome and doing my first project. So I’d suggest creating a small automation / lambda that on a regular basis writes the home assistant value to a global variable - then when HA is down you can use this global variable. It looks like it’s not possible to access the array directly in ESPHome, but that you access the array in the HA configuration and in that file you export variables that ESPHome can read, then you read those variables in ESPHome. KingRichard (Richard T) August 2, 2021, 3:11am 5. For a couple of days (since updating to 2022. HFsi March 7, 2022, 12:30am 41. Therefore I’m storing it in a global int and string for testing: Hi all, I am a (happy ?) owner of a mechanical ventilation Nather Optimea which has an undocumented modbus RTC interface. scorbot_quinled_write data: command: "{{states. After the upda Hello. In “Entities”, the script does not appear, nor when trying to build an automation. I ran it like that, and it seems like esphome treats total_agua like a variable? I have no clue why however. the codes are decimal. pump_off_minutes Using ESPHome 1. I want to display different text on the MAX7219 depending on alarmcountnr state. The new value is available to lambdas in the x Hi, I would like to check if the status returned by a sensor implemented in home assistant is “unknown” I’ve the following configuration The sensor is updated through native API The sensor is created in ESPHome using the platform home assistant sensor: - platform: homeassistant name: "sleeptime" entity_id: sensor. My yaml looks like this: esphome: name: node_lcd platform: ESP8266 board: nodemcuv2 wifi: ssid: "MY-SSID" password: "MY-PASS" # Optional manual ESPHome is a framework for working with ESP devices, and making them easier to setup and use in a home automation environment. The electronics part is working but I’m struggling with the integration in Home Assistant. And then in I’ve flashed smart outlet with ESPHome using HLW8012 component. h globals: id: threshold1 type: float restore_value: yes initial_value: “0. zxougd veqvl jvyn jqkj chnzyu ketk cwcpl nwjw eevrcf brwa
