Automatic phone pickup machine

thingiverse

We live in an apartment building with two entry gates. To be let in you need to push a button on each gate, which calls our in-apartment telephone. We pick it up and push a button to let someone in. We have to do this twice, for both gates. This has now been automated, thanks to Home Assistant and ESPHome. I have created a 3D-printed wall attachment, which holds two servos and a microphone. It’s all connected to an ESP32 and it works like this: The phone rings when someone pushes the button outside. The microphone detects this ringtone The pick-up-servo lifts the receiver. The other servo pushes the “open door”- button It then lets go of the button and hangs up the receiver - and moves out of the way so you can also pick up the phone manually if you want to. I have an input boolean I can activate, which turns automatic answering on or off. Normally I have set it to just send an actionable notification to my phone when the phone rings, with an option to open the gate from there. Video here: https://www.youtube.com/watch?v=eGmKvuyp2_s 3
