This ESPHome based doorbell is a modified Wemos Relay Shield for D1 Mini with an integrated buck converter to power the Wemos without the need of an external power source.

The doorbell has 3 connectors to make a “dumb” classic doorbell smart:

  1. Power in: here goes the power from the doorbell transformator (AC/DC 40 volts max)
  2. Doorbell: here goes the doorbell
  3. Switch: here goes the push button placed at the door

    I know absolutely nothing about electricity or doorbells 🙂
    Currently I have a very simple doorbell. It uses a push button (puls schakelaar) and a bell. In between there is just a simple (what I believe to be) converter. Please look at this picture:
    At the moment, the bell will sound for as long as the button is pressed. A lot of the times people press the button for shorter than 1s. I currently use a z-wave door sensor and stuck it to the converter using sticky tape. This works because of the magnetic field but it often doesn’t trigger on short presses.

    Could you tell me if this product will work for me and if the short button presses are an issue? Thanks!

      That looks as the perfect setup! A simple transformer, simple doorbell and simple push button. As long as the voltage is below 40-ish volt, it should work! I’ve programmed my doorbell that every push, wil ring the bell 3 times. You can choose anything you like! You could also choose as-is … push on the button is the bell ringing (same as you have now).

    Works like it should, easy to install! Just a casing would have been nice, as now it’s just dangling there 🙂
    Had to wait a bit for the delivery, but that wasn’t an issue for me, thanks Marcel!

    Will there be an ethernet version of the doorbell available?
    I prefer to use ethernet, as these devices can better be on ethernet and keep wifi free for other devices.

    • Marcel

      I can have a look for that…. Not on short terms… maybe by the end of the year.

    Works as advertised. Easy to install, nice packaging and fast delivery. Thanks Marcel!

      You’re most welcome Nick 🙂

    HI Marcel, just ordered 2 ethernet P1 but would like to have the esp doorbell too… any idea when they will be available ?
    (sorry to place this here but i did not find a direct contact email ..)

    • Marcel

      No problem Philippe, it looks like I can make another 4. Yet I dont see an order from you… is that right?

    I have been searching for this for about a year now. Of course I could try to build it myself, but never had the time. And here it is so neatly designed as a hat with functioning firmware. It couldn’t be better. I look forward to getting a second one as well as a meter reader once they are back in stock! Hope that happens soon.

    • Marcel

      Yeah soon Mahmood, I’m working on a batch which will arrive soon.

    Is it possible to connect a 2-wire camera (with bell button/switch on it) instead of a normal switch at the door?
    I have a camera with a button that just needs to be fed with the power from the bell transformer over these 2 wires.

    Info on wiring as they supply:

    • Marcel

      No, that’s not going to work unfortunately … thats a whole other setup.
