Relay Switch

Hello, I am looking into powering this module from the mains (as the relays will be used on 230V as well).

It looks like the PCB was designed with this in mind, with an unpopulated "M1" area that looks designed to accept another PCB on top.

I assume that this was made for a readily available AC-DC converter? What would be a pin-compatible reference?

The markings say "ZJW-1" and "M1".

Thanks in advance :)

I am thinking of buying this Garage Door Opener. But I need to know if we will still be able to use the manual control panel on the wall. Do you have instructions that explains how to do this (if possible)?

I like to have a 2 channel relay switch, preferably with Tasmota software.

Athom only has a one channel solution (3 way relay). The curtain module is one of the smallest on the market for integrating behind a wall switch.

As the curtain module has 2 switch inputs and 2 relays (I know about the 10A maximum current, but I only use them to switch 2 lights), it should be possible to use it as a normal 2 channel switch.

I assume I can switch off shutter mode (setoption80 0) and reconfigure Tasmota.

Does anyone have experience with this? Is the product wired to make this impossible, or do you not recommend doing this? Please let me know?

I changed my box and I no longer see the Wi-Fi with the new box. How do I make the Wi-Fi reappear when starting the relay?
