I would like to have my Fytur blinds controllable via Home Assistant but also via the Tradfri open/close remotes I have. I need for the remote controls to work if Home Assistant is offline. Do they support “direct binding” (not sure if that’s the correct term) - in other words, can the remote communicate with the blinds directly? Or can it only be controlled through a coordinator?
The blinds are firmware “0x24040013” (24.4.13) and the remotes are firmware “0x24040006” 24.4.6. I’ve read that with the remote firmware they no longer support group bindings and only support direct binding, though I’m not really clear on what the implications of that are. I have used ZHA to set up the device binds (and used zha_toolkit.binds_get to confirm) and can control the blinds but only when Home Assistant is online. If I shut down Home Assistant the remotes no longer control the blinds.
Am I missing something or does the desired functionality not exist? If I was to downgrade the remote firmware to the older version that allowed group binding would that enable the desired functionality?
well I decided to give Zigbee2MQTT a try, so I removed all my zigbee devices in the ZHA intergration, removed the ZHA intergration, then installed the Zigbee2MQTT Add-On. I first added an ikea signal repeater, then the blinds, then the open/close remote. Then on the open/close remote’s page within the Z2M add-on web UI, on the bindings tab, I set a new binding with source = 1, destination = my blinds, and clusters = Closures. Hit the bind button and could now control the blinds with the remote. Shut down Home Assistant VM and could still control the blinds. So I guess it was really that simple…and ZHA sucks lol…can’t believe I wasted a whole day troubleshooting in ZHA when I got it working as intended in 15minutes with Z2M
Ensure both the blind and the open/close button are on your zigbee network and in home assistant
Remove previous attempts to bind the button and blind by using the unbind feature in ZHA (remember to keep the button awake by pressing it)
Ensure there is no residual binding by running zha_toolkit.binds_get against both the switch and the blind. (The only bindings at the bottom of the response should show the co-ordinators IEEE)
You will have to wake the switch whilst performing the command by repeatedly pressing it
Use ZHA toolkit’s zha_toolkit.bind_ieee. Press perform action whilst repeatedly pressing either open or close. When the blind springs into action the bind has completed successfully.
