MHCOZY Zigbee Dry Contact Relay for Lights, Garage Opener etc

I’m trying to get mine working with my garage doors.

If I connect them as normally open and set them as momentary then I can use them. But the wall buttons that come with the garage door opener only work off & on.

Did you have that issue? If so, how did you get around it?

Does this device works in home assistance?. The description says needs a tuya router and I guess runs only over tuya software? How did you connect it to home assistance?

Without Tuya hub, just a Zigbee dongle with Zigbee2MQTT or ZHA

I’m not sure what you are getting at… my wall switches are normally open contacts as well. I just connected them in parallel.

I think the relays operating oppositely (new word I just invented) is to be able to drive reversible motors directly.

Yeah I just put the “???” as a placeholder for multiple uses.
