a16 as basis for a security system
#1
I was planning to use my A16 to form a security system, and while door sensors are easy enough, I'm just a touched confused over how to connect alarms, buzzers, and a motion detector...

A four-wire motion detector needs two of it's wires to be connected to a 12v power supply (I think?) and it's two alarm wires can be connected directly to one of the dry digital inputs.

I believe that I'll then need to connect the siren and alarm to the mosfet outputs via two relays, which will then also have to be connected to their own power supplies?

Am I correct in this assumption? I purchased three 12v power supplies with the board, but I'm now worried that I'll need to purchase another one just to hook everything up! Am I correct in assuming that none of them can be powered via the board's 12v power supply? Can any of them be connected to a 12v power supply in sequence. *Especially valid because an alarm shouldn't ever be sounding (drawing power from a supply) at the same time as a buzzer.

And thus far I've connected it to Home Assistant via Esphome, but because my wireless networks have been hacked before I'd rather limit the A16's exposure to potential hacking attempts. Is there any other way to connect the A16 to Home Assistant so that it doesn't need to be constantly connected via ethernet?
