Aiyo.... You aren't supposed to supply different Voltage....
Ampere slightly higher is okay; device will use and pull according to its need. But different Voltage, ... aiyo.... you better pray that thing isn't fried and can last as design intent.
The board is designed to take in USB 5V, or DC 8-80V. So 12V from battery is within specs.

Just get a 12V to 5v converter, problem solved. If you are in KV I got extra. I used it to convert my 12v solar battery to charged phone & also power up my 5V DC IP camera.
I'm not sure if using 5V would work now... but I'll try with an external 12V supply perhaps.

Autogate box there should have 12v power what, why do you connect it to the battery?
Anyway, I also used a usb to power my relay and connect the relay to the switches in my house instead of having to install it in my autogate box. It only draw very minimal power (<1w). I did so to avoid having it baked in the sun and also for wifi stability.
How do you wire the usb to power the relay and where do you hide the board? Can share some images for ideas?
. Yes the power draw is tiny... not sure why it doesn't power up with the 12V battery.

My ewelink 2 channel autogate switch works with the same logic as yours. I can hook it up via micro usb to a normal power adapter (5V1A) or to a 12V battery via the terminals (which i am using). I think you should look for your seller to get some feedback/trouble shooting . Hope your board is not defective.
Yes, trying to contact the seller back... weird the 12V battery didn't work, but the USB working. I prefer to connect it indoor as I have another switch internal... but problem is don't know where to hide the board.
