About

An ESPHome firmware that connects a Comelit Simplebus 2 intercom to Home Assistant. The board is powered from the 2-wire bus itself and taps it directly, so no extra wiring is needed.

Boards are shipped pre-flashed with this firmware. You only need the button below if you are flashing a blank board yourself.

Installation

You can use the button below to install the pre-built firmware directly to your device via USB from the browser.

After installing

Connect to the comelit-default Wi-Fi network the device creates, enter your Wi-Fi credentials in the captive portal, and Home Assistant will discover the device automatically. Firmware updates then arrive on their own as an update entity. Change the the intercom address entity to match the address of your intercom, and the binary sensor will go on when someone call your intercom
