Hue lamp no updates received

katagia · September 9, 2024, 6:47pm

Hi

I’m using home assistant with ZHA and a sonoff zigbee dongle. The hardware worked fine with iobroker.
I control a hue lamp (LTC021) and several Osram bulbs.
The Osram bulbs are working fine but I have problems with the hue lamp.
When the lamp changes it’s state and the state change was not issued by home assistant, there is no state update.
Sources for state changes besides of home assistant could be a directly connected dimmer switch or the lamp dimming itself with the move command.
When I use the cluster function to read an attribute, e.g. on_off, the correct state is returned. When I manually issue the cluster command, home assistant logs the state change and than it also updates the state. Without running the cluster command, the state is alway the last state which was set by home assistant.

My Osram bulbs behave different. When I use the remote to change the state they send the state change themself. I never had issues like this with iobroker and its zha implementation.

I’m still new to home assistant so I’m a little bit lost. Does anyone has an idea how to fix that?

Thank you very much.

Try re-pairing it. Delete it first, then pair it again.

Follow methods here to restore your Philip Hue bulbs/lights back to their factory default settings first using “Touchlink” via a Hue compatible remote or dimmer switch product before you can finally pairing/joining them to ZHA → https://www.home-assistant.io/integrations/zha#add-philips-hue-bulbs-that-have-previously-been-added-to-another-bridge

After that and another re-pairing they should be be able to complete the ZHA inteerview proess and be discovered properly. The reason for you usually need needing to factory reset each Philip Hue device before you can pair/join it to ZHA properly and the issue there is that Philip Hue device with older firmware deviated from the official Zigbee specifiation and thus could not simply be factory reset by pressing a hardware reset-button or just turn the power off and on to the device in a certain order with correct timing a with many other Zigbee devices, for Philip Hue devices with older firmware you instead need to factory reset it via “Touchlink” as explained in ZHA documentation under troubleshooting here → https://www.home-assistant.io/integrations/zha#add-philips-hue-bulbs-that-have-previously-been-added-to-another-bridge

If anyone here is a a developer and link to contribute to ZHA please see this request to ZHA developers:

Allow factory reset of Philips Hue Zigbee Light Link (ZLL) devices through TouchLink?

Feature request not sure belongs in Zigbee gateway library or [zigpy-cli](https:…//github.com/zigpy/zigpy-cli) as a tool, but think should be added to [ZHA integration](https://www.home-assistant.io/integrations/zha). Anyway, for the sake of making ZHA more user-friendly, please consider adding support for factory resetting older Philips Hue Zigbee Light Link (ZLL) devices through Touchlink (like Zigbee2MQTT and the hue-thief script can do) as that would make it much more user-friendly to pair/join Philips Hue bulbs with older firmware that has previously been added to another Zigbee Gateway (like example the official Philips Hue Bridge) but then not been properly removed and reset. * https://github.com/vanviegen/hue-thief/ hue-thief (with a EZSP-based Zigbee adapter) is a Python script that can also be used factory reset Hue devices through Touchlink: _**Hue Thief will scan all Zigbee channels for ZLL-compatible bulbs that are associated with any Zigbee network. When a bulb is found, it will blink a couple of times, and the application will ask if you want to factory reset this bulb. (If you didn't see any blinking, you may be doing your neighbours a favour by choosing 'N' here. :-)) That's it. Your now factory clean bulbs should be discoverable through whatever means your bridge/software offers.**_ * https://www.zigbee2mqtt.io/guide/usage/touchlink.html#factory-reset-device Demo video showing Zigbee2mqtt factory reset Hue bulb with Touchlink: * https://www.youtube.com/watch?v=kcRj77YGyKk Problem to solve: Philip Hue devices with older firmware can be a real pain to factory reset if you do not have the official Philips Hue Bridge because they deviated from the official Zigbee specification, so older Philip Hue lightbulbs are only capable of being factory reset via Touchlink, and as such it is not possible to factory reset such older Philip Hue devices by just pressing a hardware reset-button or use the more common power-cycle reset method (i.e. simply turn the power off and on to the device in a certain order with correct timing a with most other Zigbee devices. * https://www.zigbee2mqtt.io/guide/usage/touchlink.html As it stands right now ZHA end-users have to jump through some hops before they can properly pair/join a previously used such Philips Hue lightbulb device to ZHA if they do not still have their official Philips Hue Bridge, and the current workarounds is to either use a Hue compatible remote or dimmer switch product or hue-thief reset the bulb/light via Touchlink. Only after a such factory reset can such older Philips Hue bulbs easily join ZHA (or other compatible Zigbee gateway). Those workarounds are covered in ZHA docs under troubleshooting here: * https://www.home-assistant.io/integrations/zha#add-philips-hue-bulbs-that-have-previously-been-added-to-another-bridge Having this feature would especially make it much easier for new users migrate from a Philips Hue Bridge to the ZHA integration: * https://community.home-assistant.io/t/migrating-from-a-philips-hue-bridge-to-the-zha-zigbee-home-automation-integration/620862 PS: Off-topic but you might also want to consider adding support for TouchLink commissioning which can allow users to commission and pair a TouchLink capable Zigbee device by simply putting it in very close physical proximity to the Zigbee Coordinator and selecting "TouchLink commissioning" to start exchanging keys, which is known “Touchlinking" in the Zigbee Light Link (ZLL) specification, (downside to having a such feature is that it is at risk of a security attack during the touchlink commissioning procedure): * https://www.silabs.com/documents/public/user-guides/ug103-09-fundamentals-zll.pdf

Thank you for your support. I did reset and repair of the light several times.
Discovery and pairing works fine every time. The problem that the light won’t send status updates stays.
When I use the remote or a cluster command, the status in home assistant won’t get updated.
The same hardware works fine with iobroker.

Well it should work if you first factory reset them to default setttings before pairing, so if it still not not work then make sure you have also updated Zigbee Coordinator firmware and more importantly already following all these best practice tips so the the root cause is not poor reception or interference → Zigbee networks: how to guide for avoiding interference + optimize using Zigbee Router devces (repeaters/extenders) to get a stable Zigbee network mesh with best possible range and coverage by fully utilizing Zigbee mesh networking

Sorry for my late respond, got no internet for 3weeks.

@Hedda: I tried it several times it’s jsut not working.
Since I switched from ZHA to Zigbee2MQTT, it is working now.
