My wife and I are both Deaf. We had a wireless doorbell system when button is pressed, it send a signal to several of my flasher receiver in the house to alert us that someone is at the door. We recently purchased a doorbell camera and hook it up to a hub so when doorbell is pressed, an event is t…

Shelly1 does have a dry contact output between O(Output) and I(Input) Only Shelly1 does this though, the others have a voltage output on O I use Shelly1s this way, running on 12V with esphome (as well as using the SW connection for a binary sensor)

It may work for me then. All I need to do it power it with a 12v adapter then connect I/O to replace the button on the wireless doorbell transmitter? When an event occur, it’ll make a close contact acting like pressing a button on doorbell?

Yep I just checked… I was fiddling with mine as a doorbell replacement… so I had an old power supply wired up already… don’t laugh at how old it is … [image]

Yep, just set it up like that in epshome or use tasmota or standard firmaware and mqtt

I have that power supply boxed up somewhere! LOL … you had to buy plug separately for it! I am a Radio Shack fanboy when they used to sell those red boxed 2 dollars experiment kits. I was always asking for a new radio shack kits for my birthday when I was a young boy :slight_smile:

Also… I had to grind down a pair of tweezers to move the jumper… you may want to buy a pair of tiny ones…

Yeah that the kind that has interchangeable ends for different size plugs… :slight_smile: my dad had about 6 of them I kept

Easier to just pop the lid off (be careful of the attached antenna though)

Na, fingernail between the top and bottom and it pops right off. I broke the antenna cable on my first one so be aware of that, its quite short
