Picture

Notes #

Pairing #

Pair the sensor to Zigbee2MQTT by pressing the pair button 4 times in a row. The red light on the front side should flash a few times and then turn off. After a few seconds it turns back on and pulsate. When connected, the light turns off.

Binding #

The E1745 can be bound to groups using binding.

Detection cooldown (E1745 version) #

This device will pause detection of presence for approximately 1 min 37 sec after detection. In other words; with continuous detection, every 1:37 a new publish (occupancy: true) will be done. Cooldown of detection is 3 min. In other words; 3 min after last published detection (and trigger no longer present) occupancy will be published as false.

The cooldown detection timeout can be overridden by using the following device config option:

• occupancy_timeout: Timeout (in seconds) after which the occupancy: false message is sent.

Please note that setting occupancy_timeout lower than the device re-trigger time (around 1m30s) means occupancy: true will only be sent again when motion is detected after the re-trigger time. This allows an external automation system to observe the detection cycles (detection -> idle -> detection -> idle) and implement more complex automation flows. For simple automations, setting occupancy_timeout greater than the re-trigger time is probably desired.

OTA updates #

Exposes #

Battery (numeric) #

Remaining battery in %. Value can be found in the published state on the battery property. It’s not possible to read (/get) or write (/set) this value. The minimal value is 0 and the maximum value is 100. The unit of this value is %.

Occupancy (binary) #

Indicates whether the device detected occupancy. Value can be found in the published state on the occupancy property. It’s not possible to read (/get) or write (/set) this value. If value equals true occupancy is ON, if false OFF.

Requested_brightness_level (numeric) #

Value can be found in the published state on the requested_brightness_level property. It’s not possible to read (/get) or write (/set) this value. The minimal value is 76 and the maximum value is 254.

Requested_brightness_percent (numeric) #

Value can be found in the published state on the requested_brightness_percent property. It’s not possible to read (/get) or write (/set) this value. The minimal value is 30 and the maximum value is 100.

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:
