Phone Modem

The modem_callerid integration uses an available modem for collecting caller ID information. It requires a Hayes AT compatible modem that supports caller ID detection (via AT+VCID=1). Usually any modem that uses a CX93001 will support this.

When the sensor detects a new call, its state changes to ‘ring’ for each ring and ‘callerid’ when caller id information is received. It returns to ‘idle’ once ringing stops. The state event includes an attribute payload that includes the time of the call, name, and number.

This integration also offers a button to pick up and then hang up the call to properly reject it (via ATA and ATH).

Configuration

Adding Phone Modem to your Home Assistant instance can be done via the user interface, by using this My button:
