Using if on state "on" or "off"

ESPHome
1

I’m trying to show a glyph on a display if a state is “on” but I can’t seem to get the syntax right.

This always shows the image, even if the state is off

      if (id(sensor_home).state) {
        it.image(110,0,id(img_car));
      }

If I evaluate with (id(sensor_home).state == 'off' or (id(sensor_home).state == 'on' both return false.

Any ideas how to evaluate for an on state?

What is sensor_home? Please share at least the config for that entity.

I’ve defined it as:

  - platform: homeassistant
    entity_id: binary_sensor.garage_left_bay_presence
    id: sensor_home
    internal: true

The only reference I could find for garage_left_bay_presence is in my configuration.yaml:

template:
  - binary_sensor:
      - name: "Garage Left Bay Presence"
        state: "{{ states('sensor.garage_bay_left_ultrasonic_sensor')|float(0) < 2 }}"
        device_class: presence

A friend of mine did it, I can’t seem to find more about it.

To confirm, is that a binary sensor in ESPHOME?

So we can see what the sensor is doing, go to Developer Tools / Template and copy the following …

{{ states('sensor.garage_bay_left_ultrasonic_sensor')|float(0) < 2 }}
{{ states('sensor.garage_bay_left_ultrasonic_sensor') }}

Then let us know the result.

Not quite enough of the config. Is that under sensor: or binary_sensor:?

Under sensor, herewith my whole code (line 123 I’m printing the state as a float and I get nan):

@RoadkillUK I see the following:

False
3.07

@Mahko_Mahko yes, ESPHome sensor, but the entity / state is declared in yaml.

Put it under binary_sensor: instead then:

# existing sensors up to this point
  - platform: homeassistant
    id: sensor_grid_v
    entity_id: sensor.deye_sunsynk_sol_ark_grid_voltage

binary_sensor:
  - platform: homeassistant
    entity_id: binary_sensor.garage_left_bay_presence
    id: sensor_home
    internal: true

Then you can use if(id(sensor_home).state).

Brilliant! Thanks! So my mistake was declaring it as a sensor in stead of a binary_sensor in the esphome config.
