Unknown Shelly switch with MQTT

Configuration
,
1

Hi everyone!
I’m trying to connect my Shelly plus 1pm switches to HA using MQTT, I tried to follow any guide found around the web but I always get the same error: the entities are added but the device is unknown, therefore without the possibility of receiving the status or changing it. I followed the classic procedure to install and configure Mosquitto broker (with dedicated user mqtt_user) and enabled MQTT for the switch.

This is my configuration setup:

## configuration.yaml
automation: !include automations.yaml
mqtt:
  switch: !include switches.yaml
  binary_sensor: !include binary_sensors.yaml

## switches.yaml
- name: "Shelly Plus 1PM Switch"
  unique_id: switch.shellyplus1pm-blabla_switch
  payload_on: '{"id":1, "src": "homeassistant/shellies/shellyplus1pm-blabla", "method": "Switch.Set", "params":{"id":0,"on":true}}'
  payload_off: '{"id":1, "src": "homeassistant/shellies/shellyplus1pm-blabla", "method": "Switch.Set", "params":{"id":0,"on":false}}'
  qos: 1
  state_topic: shellies/shellyplus1pm-blabla/status/switch:0
  value_template: "{{ value_json.output }}"
  state_on: true
  state_off: false
  command_topic: shellies/shellyplus1pm-blabla/rpc

## binary_sensors.yaml
- name: "Shelly Plus 1PM Input"
  unique_id: binary_sensor.shellyplus1pm-blabla_input
  value_template: "{{ value_json.state }}"
  payload_on: true
  payload_off: false
  state_topic: shellies/shellyplus1pm-blabla/status/input:0

## automations.yaml
- id: shellies_get_status
  alias: Shellies Get Status
  description: ''
  trigger:
  - platform: homeassistant
    event: start
  - platform: time_pattern
    hours: /1
  condition: []
  action:
  - service: mqtt.publish
    data:
      topic: homeassistant/shellies/shellyplus1pm-blabla
      payload: '{"id":1, "src": "homeassistant/shellies/shellyplus1pm-blabla", "method": "Shelly.GetStatus"}'
  mode: single

As you can see, I’m able to find the entities in the mqtt integration, but they result unknown and not working.

Hey, had this issue myself.
First make sure to enable generic status updates over MQTT on Shelly’s Web Interface.
Then, change your value_template to {{ value_json['output'] }} and make sure to not use quotes around payload_on and payload_off values (you’re not using them in the config you posted so that’s good).
