Almost three years I published an article detailing how to remotely buzz yourself into an apartment building. In the time since, new technologies have made it even easier to interact with your home remotely. Below, I detail an updated remote door buzzer that works with mobile phones and even Apple Watches.

- On your smartphone or Apple Watch, send a Yo to a custom-created recipient
- Your door buzzer will be activated
To achieve this, we’ll be using a custom-made circuit that electronically switches the door buzzer. To control the circuit remotely, we’ll be using a Raspberry Pi home server that will receive casually authenticated signals over the internet sent via the Yo app (https://dashboard.justyo.co/).
The following items will be used to create your phone-controlled door buzzer:
