Renovent HR Medium/Large - Brink Climate Systems


  • MySensors Evangelist

    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

    • Yellow
    • Red
    • Black

    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

    • yellow-black
    • red-black.

    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.
