This gap has been raised in the forum before:
ZHA - binding to specific endpoints? - Configuration / Zigbee - Home Assistant Community (home-assistant.io)
In my scenario, I have a remote (Somfy Ysia 5 HP Zigbee) which needs to be bound to motorized window coverings (Somfy Sonesse Zigbee motors). This remote has 5 endpoints, one for each channel.
Through ZHA I can bind specific clusters on an endpoint to a Zigbee group, but I can’t bind specific clusters directly to a device:
The underlying websocket API doesn’t support additional parameters on
zha/devices/bind either to support this.
I can set up this binding using zha-toolkit from HACS, but it shouldn’t be necessary to use an extension to set up a simple binding like this.
Sample zha_toolkit command to achieve this binding for anyone who hits the same problem:
action: zha_toolkit.bind_ieee
data:
ieee: 4c:c2:06:19:xx:xx:xx:xx
command_data: 4c:c2:06:ff:xx:xx:xx:xx
endpoint: 1 # [1-5] for the SOMFY Ysia 5 remote's channels
dst_endpoint: 1
cluster: 258 # 0x0102 (258) for window coverings, and 0x0005 (5) for scenes both need to be bound for this scenario
The feature request:
- ZHA should support selecting the cluster/endpoints for direct device binding
- For the existing list for group binding, a column should be added to specify the endpoint (for devices with multiple endpoints with duplicated clusters) so they can be disambiguated
