Hass entities in conditions

ESPHome
1

Hi I’m trying to have a condition in an automation in ESPHome.

binary_sensor:
  - platform: gpio
    name: "Button"
    pin:
      number: D3
      inverted: True
#    filters:
#      - delayed_on: 100ms
#      - delayed_off: 100ms
    on_multi_click:
    - timing:
        - ON for at most 1s
        - OFF for at most 1s
        - ON for at most 1s
        - OFF for at least 0.2s
      then:
        - logger.log: "Double Clicked"
        - homeassistant.service:
            service: light.toggle
            data:
              entity_id: light.plate01_backlight
    - timing:
        - ON for at least 1s
      then:
        - logger.log: "Single Long Clicked"
        - homeassistant.service:
            service: light.toggle
            data:
              entity_id: light.bedroom_lights
        - if:
            condition:
              lambda: 'return states.light.bedroom_lights.state == "on";'
            then:
              - homeassistant.service:
                  service: light.turn_off
                  data:
                    entity_id: light.plate01_backlight              
    - timing:
        - ON for at most 1s
        - OFF for at least 0.5s
      then:
        - logger.log: "Single Short Clicked"
        - homeassistant.service:
            service: light.toggle
            data:
              entity_id: light.nightstand

Basically I only want the backlight part to be turned off, if the light in the room is on.
But this does not work. So I’m guessing I cannot use states from hass as a condition?

I still haven’t got the grasp of lambda, but yes I think it cannot evaluate against ha states only internal esp devices…but homeassistant.service can use data_template(but not service_template yet). Yesterday I was testing to have single click to turn on a smart light and long click to reduce the brightness of the same, what I did was to run a ha script via esphome ha service then in the script evaluate the state with the templates.

hm. that might be an option. Would you post your config for that?

4

Which one the esp yaml or the brightness script ?

5

the whole lot :wink:

This is the script for reducing brightness

        light.turn_on

        {% set target_brightness = (curr_brightness - 100) | int %}
        {% if target_brightness < 0 %}
          {{ 0 }}
        {% elif target_brightness > 0 %}
          {{ target_brightness}}
        {% endif %}

If you wan tto use states from home assistant in the ESP you have to add them as sensors first:

So to clear up some confusion:

lambdas are C++ code (and not Home Assistant-like jinja2 templates - try writing a full jinja2 parser for an embedded system :wink: ), so return states.light.bedroom_lights.state == "on"; won’t work. You need to first import the State into ESPHome with the “Home Assistant Text Sensor” as @tom_l said, then you can use return id(id_of_ha_text_sensor).state == "ON"; (beware of case sensitivity!)

data_template in homeassistant.service is a bit different - here HA-style templates are supported. The ESP just sends Home Assistant the full template and tells Home Assistant: “evaluate this on your own”.

Does the case sensitivity also apply to unavailable state of a light.

I want to see if a smart light is available to be toggled otherwise just toggle the relay.
