Hello,

I am testing MQTT Hub MQTT Device with a Garage Door and Lock capability.

Current behavior:

State topic:  
garagedoor/state

Received values:  
true  
false

These are received correctly and update the Homey device state.

Command topic:  
garagedoor/set

However, when I trigger Open/Close or Lock/Unlock from Homey, the MQTT Hub publishes:

value

instead of a capability-specific payload.

Example log:

OnMessage called  
SendMessageToTopic called  
received ‘value’ on ‘garagedoor/set’

Problem:

Regardless of what payload is expected, Homey always appears to send the literal string:

value

As a result, my external device cannot distinguish between:

open  
close  
lock  
unlock

because the payload is always “value”.

Questions:

1. Is this expected behavior?
2. Am I missing a payload mapping setting?
3. How should Open/Close or Lock/Unlock payloads be configured?

Thanks.
