How to Make a Wireless Door Bell With Home Assistant
Wireless doorbells are a great way of adding bells in homes or offices without using any wires. However, these wireless bells come with limited preconfigured MIDI sounds that play when someone presses the button on the transmitter unit.
Though you can toggle between the MIDI sounds and increase or decrease volume, that’s all you can do with these wireless doorbells. However, today we will build a DIY smart wireless doorbell where you can add custom MP3 sounds, or music files, that will play when someone presses the bell switch. You can also customize the setup and use the bell as a smart speaker.
Things You Will Need
You will need the following to build and set up a custom DIY smart doorbell.
- Home Assistant server running on a Raspberry Pi or any other supported device.
- 2 x Wemos D1 mini or NodeMCU boards.
- 50mm speaker.
- A PAM8403 mini 5V digital amplifier board.
- DuPont or jumper wires. You may also need a soldering iron and tin to solder joints if you want a permanent connection.
- Case to assemble all parts. You can print this 3D case.
