Since the last update the nanoleaf binding causes exceptions on every update:

Setting values still works, thing is displayed as online

Version openHAB 2.5.0~S1762-1 (Build #1762)

[olafWal]

Additional Note: Disabling the "Panels" Things make the error go away.

I can confirm this bug with Nanoleaf-Firmware 3.2.0 and openHAB 2.5.0 Release Build

[9037568]

Looks like this should be improved in the latest binding release. Can @olafWal retry?

[olafWal]

I checked the logs, it seems to be OK now
