Now I want something to happen based on the value of the sensor. RP2040: GPIO26 through GPIO29 can be used. I’m trying to get ESP to evaluate the state of both and then loop a scipt that will turn on and off a switch until the luxmeter registers a value above 200. Specifically, is it internal? If yes and you want the URL to show in Device Info, then change it by adding name: to the text sensor. Updating the entity in HA updates the value on ESPHome and vice-versa. I want it to ramp up the brightness and dim during the course of the day - I’ve done something like that in arduino ages ago, however ESPHome/yaml is new to me. Open comment sort options. clock_interval (optional, seconds): show the clock at least each x seconds, (default=60) clock_time (optional, seconds): duration to display the clock after this time, the date is displayed until next "show_screen". I have a defined a text_sensor and am feeding it with information about the water level. The device must be connected via a UART bus supporting both receiving and transmitting line. 991 x - 9846. The backstory is that I have a lambda doing some things in a loop, and I want a delay between iterations of the loop. ESPHome. All other options from Sensor. Return has to be the last thing. The state of the template switch is used to display whether the wifi is connected. yaml: In lambda function: /config/ag-pro. 2), at the end of which, I’d like to tell a ESPHome device to redraw its screen. The Analog To Digital (adc) Sensor allows you to use the built-in ADC in your device to measure a voltage on certain pins. All parameters defined here are mandatory and must be given when calling the script. A good way to test if it works is to set the input number to a random value in Home Assistant, and see if the esp indeed sets the sensor to that value at the start. Have been struggling with this problem for days and no matter what I try I am unable to get there. I tried using lambdas to drive the transition_length and delayed_off parameters but they are not templatable. 0/9. 1. time_remaining(). If you’re using the same, or a later The desired tilt is available in the lambda in the tilt variable. I’m created an input field on the dashboard, and i need this field’s value in an esphome global variable. name: ${valve_0_name} Duration. That all works with an interval, an template switch, and a time automation to set the template switch: switch: - platform: gpio name: "Hot Pump Relay" pin: GPIO12 id: relay - platform: template name: "Run Pump Allowed" id: runok optimistic: on This repo will allow you to use an ESP running ESPHome to "intercept" the WizMote button presses, and forward them to Home Assistant, or act on them directly within ESPHome. For example, if you want to only perform a certain automation if a certain complex formula evaluates to true, you can do that with templates. I’m storing the distance as a global variable in the ESPHome code upon a long button press, which is great, except for when the device would restart. YAML esphome: name: verstaerker So I have a text sensor where I want to replace every comma in the string with a newline return character. state]” Can anyone help please, this is my first with ESPHome and trying tracing help Following is my code captive_portal: output: platform: gpio id: “BuildInLED” pin: number: D4 Configuration variables: id (Required, ID): Give the global variable an ID so that you can refer to it later in lambdas. When writing a lambda for this field, then return one of the following enum values: SELECT_OP_FIRST, SELECT_OP_LAST, SELECT_OP_PREVIOUS or SELECT_OP_NEXT. xxx data: finger_id: !lambda 'return finger_id;' confidence: !lambda 'return confidence; Configuration variables:¶ lambda (Optional, lambda): Lambda to be evaluated repeatedly to get the current state of the lock. cycle ( Optional , bool, templatable ): Can be used for options NEXT and PREVIOUS to specify whether or not to wrap around the options list when respectively the last or first option in the Configuration variables:¶ trigger_pin (Required, Pin Schema): The output pin to periodically send the trigger pulse to. They may be read and/or written. For data points that don’t change very frequently updates can be skipped. The fingerprint_grow component allows you to use your R307, R503, R503-RGB, ZFM-20, fingerprint sensors with ESPHome. The switch_on of the irrigation lines will be handled by a YAML Script. So in your lambda you would need something like lv_img_from(id(fog)) instead of just id(fog). A few questions for you; Which version of ESPHome are your working with? I’m using 2022. 21600 step: 30 lambda: |-return (int) id I have the following global variable globals: - id: water_change_in_progress type: bool restore_value: no initial_value: 'false' and want to test it’s state in the following - platform: gpio pin: Neither esphome. Have a water flow meter working but want to rest the value to zero before the pump turns on. Everthing works fine, till i try to add Buttons for Volume up/down. state != "";' Would expect this to display (in Device Info)? Or do I need to do more? This depends on how you defined the template text sensor for your URL. return NAN; if the state should be considered invalid to indicate an error (advanced). - output. . Example: binary_sensor: - platform: template name: "Status Car Presence" device_c If you mean regilar BLE data from MiFlora (HHCCJCY01) like temperature/humidity, etc than yes, sure you can register all sensors at all esp’s or even better, you can populate all esp with all MAC’s configured in Passive BLE Monitor using advanced configuration. show: page1 else: - display. I haven’t tried, but something like this: sensor: - platform: template id: I am struggling with the hex-string to dec value in lambda function. log: “write to the log: Temperature too high” The command obviously works outside the Rtttl Buzzer¶. The new value is available to lambdas in the x variable. I want the device to look more like what it is supporting than have to glue things together on the Home Assistant side. Reply reply Saved searches Use saved searches to filter your results more quickly lambda (Optional, lambda): Lambda to be evaluated every update interval to get the current value of the number. 0. I’ve spent an hour or so searching for an example or clue on how one creates an ESPhome ‘if’ condition statement that contains a second ‘if’ condition inside it, and found nothing obvious. Defaults to 60s. You signed in with another tab or window. Image by Adafruit. (My knowledge ends when it comes to lambda-things): I am looking for a script for ESPHOME to read the status of a Tasmota power plug in esphome. ESPHome was much easier then Tasmota for me. parameters (Optional, Script Parameters): A script can define one or more parameters that must be provided in order to execute. For secret I wrote in the YAML substitutions: weathercloudid: !secret weathercloudid weathercloudke Instructions for parsing and building json within ESPHome. I am working with an example YAML file that is doing something odd with a Lambda. I would like to use a cover template in ESPHome to determine the current state of the cover and report back but having some issues with logic in I would approach this by using a Home Assistant Sensor so that ESPHome knows if “the air conditioner is running. As an alternative to controlling a Hi. But I just lambda (Optional, lambda): Lambda to be evaluated every update interval to get the current value of the number. Hello, I'm trying to setup a template select with lambda. This repository/library allows you to create a custom wake word for your ESPHome device. Not sure how reliable it is, but I got the scheduling bit of code from ChatGPT and it seems to make sense. wake_word:!lambda return wake_word; Disclaimer: I have never use one but maybe frequency. I am making an esphome based, motion sensor driven RGB light. Either way, an update on one side is always reflected on the other. I will have a reed switch at the very bottom of the door for signal a FULL close and a reed switch at the very top of the door to signal a FULL open. publish: id: oil_level_percentage state: !lambda 'return x - 1. If the entered string To put custom lambda expressions to work, you’ll integrate them into the relevant components of your ESPHome configuration. All sensors in ESPHome have a name and some other optional configuration options. But it requires a either a float or a string where I’d like to use an integer. state == 1;' then: - display. Has anyone done it and got an example ? I’ve tried hacking at my code but get validation errors of one type or another.

I tried I can write test using - uart. When the state for this output is updated, the write_action is triggered. BME280’s absolute pressure output has already temperature taken into account, so having it in relative pressure formula again is wrong. Dear all, I would like to return a NAN value as result of a calculation if the values do not make any sense (in my context). template. See Raw Data Parsing Lambda for more information. I have used this code to flash into my new SONOFF iFan04. You should however remove the service call (homeassistant. Normally.
