| 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$?
- Flash your ESP32. Here is my ESPHome code
- Print the parts. Thingiverse
- Solder the connections
- Assemble
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
- 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
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
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.
- 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
