I may have been over-eager to help test this one 
may I ask for a point in the right direction? I’m sure I missed something…
I started by upgrading my OH instance to 3.4.0-SNAPSHOT (Windows, installed as a service), and removed all Nanoleaf Things (and the binding) for reinstall. The controller is okay to be added as a Thing, but all panels give me this error:
(Message is:
HANDLER_INITIALIZING_ERROR
class java.math.BigDecimal cannot be cast to class java.lang.Integer (java.math.BigDecimal and java.lang.Integer are in module java.base of loader ‘bootstrap’)
Any ideas would be most appreciated, I will keep trying to find a solution or if that doesn’t work I can always go back to 3.3.0. In case it’s something with Java, I’m using Zulu 11.0.17 but can change it if needed
