Hi,

digging into MQTT and a switch.

switch:
  - platform: mqtt
    name: "Venus GX Relay 0"
    state_topic: "N/xxx/system/0/Relay/0/State"
    value_template: "{{ value_json.value == 1 }}"
    command_topic: "W/xxx/system/0/Relay/0/State"
    payload_on: '{"value": 1}'
    payload_off: '{"value": 0}'

The MQTT state is a json object. See Payload on/off.

I cant get the state extracted with the value template. Any help appreatiated.

Regards
Ralf
