Hello everyone,
I want to control a garage door with HA, controled already with switch up-down. I have Sonoff switch (MiniR4 10A). do you think can I make it works with this simple switch or should I take Ratdgo e.g ?
Thank you
You need a dry contact relay. I don’t think the minir4 has a dry contact option.
ratgdo is really only needed for lm/Chamberlain Security+ doors. There are other, more complete kits for other doors and ratgdo doesn’t really offer more for non-Security+ doors.

You can use relays for this. I use the MIMOlite for my garage door where my input sensor is a floor based reed switch letting me know if the door is open or closed and then the output sensors wired to the same terminals on the garage door opener that the button wires into to mimic pressing the button.
You don’t need a fancy pre-made device for this, it’s a pretty easy mostly plug-and-play solution with a relay (in my case the MIMO because it is Z-Wave and I use a lot of Z-Wave) but there are also wifi and Zigbee relays that do the same thing.

Hello Jerrm,
Thank you, minir4 has a dry contact, I’ll try it soon.
Don’t confuse “dry contact sensor” with a dry relay. I didn’t see any wiring diagram for a dry relay.
