The integration of Brink Renovent HR with openHAB leverages OpenTherm protocol to communicate with ventilation appliance and MQTT to communicate with openHAB.
Below is my UI (first 4 items are from addtitional sensors):
You can find all details (including programs) of my project at:
• It works as it is designed only for Brink Renovent HR integration! If you have a heating appliance based on OT as well you can use other solutions or you can extend/add heating part as well.
• It allows acess/control of all user/installer adjustable parameters (TSP parameters) if needed
• It uses MQTT (based on my tests is far more stable than base http)
• It is the cheapest way to integrate openHAB with Brink Renovent HR
This integration is not tested with Brink Renovent Excellent, which provides two methods of integration: OpenTherm or eBUS.
I have an old but working Brink Renovent HR Large which I wanted to control from openHAB.
I have bought an OpenTherm Gateway (from nodo-shop) and connected it to Brink Renovent and to openHAB using the existing OpenTherm binding. Unfortunately, after several attempts I was not able to get a stable connection between Opentherm Gateway and my Brink
Hence, I have decided to seek for other solutions and I have found another Opentherm adapter based on which I have elaborated and implemented a successful solution
