MQTT depreciation notice with latest releases

Third party integrations
1

For the last couple of release I’ve been getting warnings:

2021-04-18 16:02:26 WARNING (MainThread) [homeassistant.components.mqtt.cover] Using ‘value_template’ for ‘position_topic’ is deprecated and will be removed from Home Assistant in version 2021.6, please replace it with ‘position_template’

Sadly, I do not have the backgound to understand any of that. ( EE backgound)

It may be one of these, but I don’t know how to determine that or how to fix it.

sensor weewx:
  - platform: mqtt
    state_topic: 'weather/barometer_inHg'
    name: 'Barometer'
    unit_of_measurement: 'inHG'
    value_template: '{{ value|round(1) }}'

or

switch china:
  - platform: mqtt
    name: "china light"
    command_topic: "home/OpenMQTTGateway315/commands/MQTTto315"
    payload_on: "11083267"
    payload_off: "11083266"
    retain: true

sensor back_garage:
  platform: mqtt
  state_topic: 'home/rtl_433/back'
  name: 'Back Garage Temperature'
  unit_of_measurement: '°C'

thank you

It is none of those.

The warning message says that it is a position_template in an mqtt cover entity configuration.

[homeassistant.components.mqtt.cover]
                          ^^^^^^^^^^

Either you manually defined an MQTT Cover or it was automatically discovered. Either way, Home Assistant appears to believe you have one.

Go to Developer Tools > States and type this:
cover.
in the Entity column.

If you have one, it will be shown.

Turns out the mqtt integration had automatically discovered a “cover” for a Wyze cam I used shortly last year. It broke but was not removed from the integrations. That is why I could not find it; it was not in my configuration.yaml.

thank you all !
