Renovent HR Medium/Large - Brink Climate Systems
I wanted to have my Renovent HR Large from Brink Climate Systems automated.
Unfortunately Brink offered a € 300 solution to do this wireless within the house
I thought.. Well it must be possible to use one of the Mysensors sketches to do so.
By default this system comes with a 3 way switch that is connected to an rj11 plug on the Renovent.
The RJ11 has 3 cables
After figuring out how the 3 way switched worked it was an easy task with one of the example sketches.
- Yellow + Black = Switch_2
- Red + Black = Switch_3
- By default nothing is connected = Switch_1.
If you would like to measure voltage you will measure aroun 13,88v on
The sketch can be found here:
You will need 2 Relais if you want to switch Switch_2 and Switch_3.
Please see attached the prototype... available for around €10 .
And then within Domoticz I can control it.
If the humidity in the bathroom is over 58% kick on the fan
Oh btw. don't forget to connect the ground of the Relais to the Ground of the Arduino, otherwise it will not work.
Happy Mysensors day.
