Hi, I want to mount a wired ring doorbell on a gate post which is about 10 meters from the my house. There's two power supplies that run to the gate, one for lighting, one for gate motors. I was hoping to use one of those to power the door bell but I expected the transformer to be part of the bell. It's not, it's a separate unit. Can I mount that transformer outside? If so, what's the best way to do it so it's ventilated etc (which I'm assuming is a requirement)? Thanks!!
