Hi guys,

I have a fairly new electric garage roller door which has a RD20X2ELL Controller unit. This unit has the following wires inside:

Terminal 1 – Earth Motor WireTerminal 2 – Earth Power WireTerminal 3 – Power Brown Live WireTerminal 4 – Power Blue Neutral WireTerminal 5 – Motor Open WireTerminal 6 – Motor Blue Neutral WireTerminal 7 – Motor Close wire

I was looking for a unit to essentially make the door controllable via wifi and came across the Meross MSG100 although there are only two wires that come from the Meross unit so I’m assuming it wouldn’t work on it’s own (I’d need open/close/com I’m guessing?).

Here is a pic of my controller box:

If this isn’t possible with the Meross, does anybody know the best way to make this “smart” at all? Preferably so I can integrate it with Google Home.

Thanks in advance!

    The Meross doesn’t connect to your existing garage door opener at all. There are no wire between the two units.

    The Meross just pretends to be the remote control. It receives commands via WiFi then pretends like it is the remote control pressing the button.

    So it will only work with your opener if it know the wireless standard used by it. Check out their compatibility list.

    If you opener has a remote release contact on the PCB, you could do the same as the Meross with a smart relay and a door sensor.
