Tuya Smart 4CH - garage door control, channel division and momentary button setting

Hi. I have this oh-so-controller on WIFI Link TUYA 4CH DC 5-32V 4 channels Wifi+RF voltage free I plan to use it for the garage door. Only a momentary contact is required for the garage door. My question is if I connect this under the Tuya smart app will I be able to split these 4 channels? I plan to connect this under smartthings to be able to control 3 gates. I don't think there will be a problem with this. And is it possible to set a momentary button in the settings? In the sense that after clicking on it in the app, the module closes the circuit for a second and that's it.

I have such a module, and in the app you can only select the operating mode of the external button connected to the module (this is how I have the version with 5 pins for connecting an external switch). The control via the app is the same all the time, i.e. manual on and off. You can, however, make the automation so that after switching the switch on, the relay waits for e.g. 2 seconds and then switches back off.


Automation done in such a way will switch off the relay a second after it is switched on by the application or by the built-in button.

I understand. Can you still check how the tuya smart is hooked up to the smartthings with this relay? Are there split channels or what? Or under google home. I intend to automate everything under e.g. google home or smartthings so that I don't have to carry my phone or anything else. Just the watch. And the watch also has limitations, only smartthings and google home are available. I was thinking of trying to create an app for the watch, but nowhere have I found any wizard or programmer who could do this. In principle, it is enough to send a request to the relay.

As far as I can see, Smart Things only detects the first relay in the module on both the 2 channel and 4 channel versions, the 1 channel version did not, or it was me who did something wrong. On Google Home, everything works flawlessly. I personally integrate everything using Home Assistant installed on the home server.

How did you add the relays to the google home? And I wrote with the seller and he wrote that you just need to set the mode to monostable where do you set such a thing?

I added relays to Google Home by linking Tuya and Google accounts, switching in the app to monostable mode only changes the mode of the external switch, not the one in the app. After adding the automation that switches off the relay after one second, even through Google Home everything works without a problem. The switch mode changes in the Tuya Smart app, about here: .
