Elmax
elmax
The Elmax integration enables Home Assistant integration with ELMAX control panels. Elmax panels are domotic systems focused on intrusion detection and home surveillance.
In Apple Home through HomeKit Bridge
What HomeKit Bridge makes of each kind of entity this integration creates, read from its source code. A device only gets the ones that apply to it.
| Entity | Shows up as | Note |
|---|---|---|
switch | Switch or outlet | |
cover | Blind, garage door, window or door | |
alarm_control_panel | Security system | |
binary_sensor | Sensor (contact) |
What people report
Elmax panels gained a local API in 2023, but the VENUS alarm panel only works through the cloud and users report timeouts and unavailable entities.
