Home assistant sensor does not update

ESPHome
1

Hi,

I’m trying to do something similar to the thread below.

I have a helper in HA with an opening and closing time I’d like esphome to read the value, store it into a global variable and then perform automations based on the values. This is for cases where the connection to HA is not working when the automation is triggered.

Below is the code I’m using just to print the value in esphome however no value is ever published even when I change the value in the helper.

sensor:
  - platform: homeassistant
    id: open_time_temp
    entity_id: input_datetime.chicken_door_opening_time
    attribute: datetime
    on_value:
      then:
        lambda: |-
          ESP_LOGD("main", "starttime hour value is: %f", x);

Alternatively I also have a bit of code that just publishes the value of open_time_temp every 10 seconds however the value is stuck at 1073453424 ( I presume this is default value assigned).

time: #time triggers to open and close the door in case the wifi is turned off at night
  - platform: homeassistant
    id: ha_time
    on_time: 
      - seconds: /10
        minutes: /1
        then:
          - logger.log:
              format: "values %d "
              args: [ 'id(open_time_temp)' ]

Any help would be appreciated as I’m slowly loosing my mind!

Is datetime actually a valid attribute of an input date/time?

I think the attribute you need is timestamp, which for an input that accepts just a time (as opposed to a date or date & time) returns the number of seconds since midnight.

So you’re right! Started trying different attribute types and got lucky, its a bit tricky that there is no list of them for esphome (at least none I could find anyway).

Went absolutely cacked trying to figure that out.

Thought I’d add my code in case someone else has a similar issue. Passing the data to a global was a bit unintuitive, I tried using the "then : - globals.set: " combo but couldn’t figure it out so went with a lambda

globals:
   - id: open_time_sec
     type: int
     restore_value: no
     initial_value: '28800' # 8am in seconds  
   - id: close_time_sec
     type: int
     restore_value: no
     initial_value: '72000' # 8pm in seconds


sensor:
  - platform: homeassistant
    id: open_time_temp
    entity_id: input_datetime.chicken_door_opening_time
    attribute: timestamp 
    on_value:
      then:
        - lambda: |-
            ESP_LOGD("main", "starttime value is: %d seconds", int(x));  
            id(open_time_sec) = int(x) - 5*60;
          #set the global variable to the value set by the field. minus 5 minutes from it to give time for the system to boot up and connect if needed
  - platform: homeassistant
    id: close_time_temp
    entity_id: input_datetime.chicken_door_closing_time
    attribute: timestamp 
    on_value:
      then:
        - lambda: |-
            ESP_LOGD("main", "starttime value is: %d seconds", int(x));  
            id(close_time_sec) = int(x) + 5*60;

As the input is a Home Assistant sensor (rather than an ESPHome sensor), there definitely is a list.

I find the easiest way to get HA attributes is via the Developer Tools in HA.

Good shout, definitely a good reference to have going forward.

Thanks for helping with this!
