Hi,
This is not a very big problem, it is expected especially for battery devices.
If you don’t like this, you could try unpairing the device and pairing it again. The flag remains set if the device does not reply to some query. Not all of them behave well, whence the ‘config pending’. Especially the battery devices can go to sleep before having a chance to query/config them entirely.
There should be some channels exposed that allow changing values, but it’s probably not straightforward. It probably exposes the same functionality as other Philips Hue light bulbs so I’ll simply make a file for ‘1b’ as well. In a couple of days it should be available in nightly. Please let me know if it works.
Sincerely,
Adrian Roman
