openhab-addons: [CoolMasterNet] devices don't update - errors in log when binding restarts

There was a previous issue (solved) with the binding stopping updating devices, and errors when the binding restarted.

There now seems to be another similar error. Same symptoms - binding will communicate outbound commands to the coolmasternet but stops updating state changes to openhab. Different log errors - see below.

Many thanks!

still working!

thank you! Your next trick should be to write a binding from scratch for a device you don’t own and have never seen.

Dan1001 on Jul 12, 2018

Thanks! That has started without error, and provided a few updates. I’ll see how it does over the next 24 hours and report back.

Still pretty impressed you can debug this without actually having the device. If the problem persists I could temporarily give you remote access to the device and see if that helps (if you promise not to set all the thermostats to 40C and turn the heat on…)
