SKU: Doorbell-v2.0 Category:


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

    Excellent little device to make my dumb doorbell a smart doorbell. I made an order on Thursday afternoon and got the package in my mailbox the next day, so I was lucky it was in stock. It’s easy to hook up and for me it is a big advantage to be able to flash new firmware or my own firmware, because I like to tinker with DIY home automation gadgets. The fact that you can power it using the existing power transformer made me buy it almost instantly.

    Will the previous design still fit in the 3d-printed case? Or do you have a case available for us running on the previous design?
