Notes #

Configuring Inputs #

In case the input(s) need to be reconfigured (e.g. to use stationary switches instead of momentary ones or vice versa) this can be done in the same way as it is being done for the ubisys C4.

(Re-)Binding and/or Decoupling #

Also see the ubisys C4 documentation, example use cases:

• Use the second input to control a different Zigbee device (S1-R only, S1 only has one input)
• Completely decouple the input(s) from the local load

When decoupled, ‘action’ will be published when pressing the attached switch button.

Device type specific configuration #

How to use device type specific configuration

• simulated_brightness: Set to true to simulate a brightness value (default: false). If this device provides a brightness_move_up or brightness_move_down action it is possible to specify the update interval and delta. This can be done by instead of specifying true:

simulated_brightness:
  delta: 20 # delta per interval, default = 20
  interval: 200 # interval in milliseconds, default = 200

OTA updates #

This device supports OTA updates, for more information see OTA updates.

Exposes #

Switch (l1 endpoint) #

The current state of this switch is in the published state under the state_l1 property (value is ON or OFF). To control this switch publish a message to topic zigbee2mqtt/FRIENDLY_NAME/set with payload {"state_l1": "ON"}, {"state_l1": "OFF"} or {"state_l1": "TOGGLE"}. To read the current state of this switch publish a message to topic zigbee2mqtt/FRIENDLY_NAME/get with payload {"state_l1": ""}.

Switch (l2 endpoint) #

The current state of this switch is in the published state under the state_l2 property (value is ON or OFF). To control this switch publish a message to topic zigbee2mqtt/FRIENDLY_NAME/set with payload {"state_l2": "ON"}, {"state_l2": "OFF"} or {"state_l2": "TOGGLE"}. To read the current state of this switch publish a message to topic zigbee2mqtt/FRIENDLY_NAME/get with payload {"state_l2": ""}.

Power (numeric, meter endpoint) #

Instantaneous measured power. Value can be found in the published state on the power property. To read (/get) the value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/get with payload {"power": ""}. It’s not possible to write (/set) this value. The unit of this value is W.

Action (enum) #

Triggered action (e.g. a button click). Value can be found in the published state on the action property. It’s not possible to read (/get) or write (/set) this value. The possible values are: toggle_s1, toggle_s2, on_s1, on_s2, off_s1, off_s2, recall_*_s1, recal_*_s2, brightness_move_up_s1, brightness_move_up_s2, brightness_move_down_s1, brightness_move_down_s2, brightness_stop_s1, brightness_stop_s2.

Linkquality (numeric) #

Link quality (signal strength). Value can be found in the published state on the linkquality property. It’s not possible to read (/get) or write (/set) this value. The minimal value is 0 and the maximum value is 255. The unit of this value is lqi.

Manual Home Assistant configuration #

Although Home Assistant integration through MQTT discovery is preferred, manual integration is possible with the following configuration:
