I have the Simplisafe integration working, and it has discovered all the connected devices apart from the siren outside the house. The native Simplisafe app shows it under the “Bell Box” category.
I used the Simplisafe Python module to query Simplisafe and it is definitely being returned under the sensors, so wonder if this could be included in the HA integration?
This is what the Python module shows:
Name : FrontHouse
Serial : xxxxxxxx
Type : DeviceTypes.OUTDOOR_ALARM_SECURITY_BELL_BOX
Settings : {‘alarmVolume’: 2}
It looks like it should just be a case of adding this type and mapping to the binary_sensor.py file.
