My RF doorbell just broke and I want to build a new one
I don’t have much time though, and I want it as simple as possible. But I want it wired (at least the bell part, maybe also the button) and controlled by Home Assistant.
I’m thinking of using ESPHome or a raspberry pi. I don’t really care, I have the wiring to a central space in the wall.
But I cannot find a simple bell, that I can control from such a device. Maybe I’m overthinking this, but my only constraints are:
it needs to be loud enough to be heard around the house
it needs to be relatively small to fit inside a wall box. I want to print a simple enclosure on my 3d printer.
if possible, it should play a simple melody instead of a single note. But this is optional.
What kind of wiring? Mains power, low voltage wiring? From the exterior to interior?
‘Normal’ doorbell hardware (in the US at least) runs of relatively low AC voltage. You can have an ESPhome detect the button press (any gpio to ground with a standard doorbell switch) and then use a small relay to control if the bell gets activated.
thanks four your response. I know Frenck’s tutorial. Problem here is the size factor. I want to find something smaller.
I have mains as well as a cat7 cable from a central location in my house. I could run low voltages from there.
This is inside. Outside is a little more difficult, I would have to run some extra cables. So I might go with a simple ZigBee button for now and improve that later.
