Just thermostat with mqtt

[Arden]

hi there

interesting project

i already have openhab running at home with a mysensors

So what I really would like is to just use the thermostat side and mqtt to and from my existing openhab

is this possible ?

[Arden]

just thought would it just be as easy as pointing the second server at the master for its mqtt requests

Welcome to the club
I have definitely done this with the previous version of openHAB with no problem.
In 2.4 (image and code to be released in the next 1-2 weeks) MQTT server is defined in the default.things file in this line:

Bridge mqtt:broker:mosquitto "Mosquitto MQTT Broker" [ host="localhost", secure=false, port=1883, clientID="mosquitto", retainMessages=true]

simply changing “localhost” to your other machine’s IP (and maybe credentials) should be enough. A little googling around shows it is a trivial configuration change.
