ZHA: identify device - only when it's on?

[ChristophCaina]

The problem

OK, I'm Not Sure If this is really an issue or maybe a Feature / Change request... Or If it is even possible at all...

We have some Christmas Decoration, which is Equipt with a zigbee light bulb.

The zha Integration provides a Button "identify" - euch will Trigger a flashing / blinking of the lightbulb.

But: This is only working, when the light bulb is switched on. I think, it would make Sense, If the Button would Trigger the effect Always, Independent of the state...

This is only working, when the light bulb is switched on.

The implementation of the identify command is likely incorrect on your bulb then. I doubt this can be fixed properly. Please upload the device diagnostics file though. It can be found on the device page, three dots, download diagnostics.

[ChristophCaina]

Thanks. You are right, it is only thus specific bulb... Others are working as expected.

Here are the device information & diagnostics... zha-c4b8635ee52ce7e7eebcdac6d44af482-LEDVANCE P40S TW-25be6d7667fbe50e9673d5a10df74b7e.json

Hmm, LEDVANCE/Osram is definitely not known for a great implementation of everything Zigbee. The best we could do is add a quirk to intercept the identify command, then send an on() command, send the identify command, and finally send off() with a delay.

Otherwise, you could have a look if LEDVANCE provides a firmware update for your bulb here. OTA updates for LEDVANCE can be enabled in your configuration.yaml. More info is available in the HA docs and in the community wiki.

So... I guess, there's no new firmware available?

Not 100% sure, if MAYBE an earlier update attempt was successfull...

But even if: there's no change on the device... maybe, a quirk would be an idea?
