{ “SetRoomTemperature” : “{{value}}” }

Did you try this example:

MQTT Hub/Gateway

MQTT Devices are now able to handle JSON input & output. Version 3.1.0 MQTT device: grab input value from json messages (jsonPath) MQTT device: format output message payload to json (JSON-T template) [image] I added two optional config parameters per capability: value path: point to a value within the JSON payload of the state messate using JSONPath. output template: format the output using JSON-T. Both string & object output are supported. All values from the device state (capabilities)…

So:
{ “SetRoomTemperature” : {{value}} }

HUB Version 3.1.0+
