Parts needed
| Part | Price | Comment |
|---|---|---|
| LILYGO TTGO T-Camera ESP32 | 15$ | Get the fisheye option! |
| Illuminated Momentary Button | 1$ | Needs to be 12 mm. Pick the color you like. 12V |
| M3 x 16mm | idk | |
| 4 chord wire | idk | A regular Ethernet cable would do |
| 12V PSU | idk | I'm sure you have something laying around. |
| 3.3V PSU | idk |
Since I ended up having much of what I needed already laying around, I do not have a completely full bill of materials. But 16$ + some idk = approx 20$?
How
- Flash your ESP32. Here is my ESPHome code
- Print the parts.
- Solder the connections
- Assemble
Connections
Follow the connection diagram and solder the wires as follows. One note is that you have to mount the button in the case before you solder everything.
IRL examples
Assemble
- Print the parts and assemble your ESP32 in it.
- Unscrew the fisheye lens before you put the board into the front piece, and screw it back on again.
- Fasten the button.
- Thread the cable though the wall where you want to mount your doorbell and thread the cable through the back piece. I tried to seal things off a bit by filling the gap in the back piece with a glue gun.
- Mount the back piece where you want your doorbell.
- Make the final connections and fasten the front part of the doorbell to the back piece using the M3 screws. As you can see I used dupont wires to make connecting and disconnecting easy
Home Assistant Scripts
When the doorbell gets pressed a number of scripts gets activated.
- TTS gets sent to the Google Homes
- Our phones gets a notification
- A snapshot is taken and saved
- Selected lights flash blue to notify us visually
DISCLAIMER
This project is to be considered as a work in progress.
The 3D-printed parts is not a finalized version, and should be improved. I welcome anyone to remix the designs and make this project better.
This revision of the ESPHome-VideoDoorbell is more of a proof of concept. All the pictures were taken the summer of 2019, and the doorbell has survived the Norwegian winter in Trondheim untill now. I haven't even fastened the front piece to the back piece, but it has still survived.
Alternative cases
Some cool people have been remixing and created alternative versions of my quick and dirty case. Check them out!
Things to improve
- 3D models should be improved. The back piece should have room for threaded inserts.
- The push button should be a 3.3V (or something around that) so that the wire going to the doorbell only needs two chords. Then you would also only need one PSU instead of a seperate 12V just for the button.
- The push button should be a slimmer design. This enables the 3D models to be slimmer and have a lower profile.
- Some sort of sealing around the exposed parts of the ESP
