Crash when updating thermostat value

[0ff]

Sometimes (i.e. I can't reproduce it), updating a value crashes Homebridge. Seems like the context (this) is missing, any Ideas?

EDIT: I'm running 2.0.8

Are all other devices working right?

[0ff]

Yes, and in fact the very same action works most of the time (which, I know, is weird). Maybe it has to do with how the change is triggered or something? If you can think of anything, please let me know and I'll try helping you debug it.

Can you look for a "didFinishLaunching" entry in your log? Is there such a log entry before the error log?

[0ff]

Yes, it's there:

This is after the crash. Is there a "didFinishLaunching" before [2018-3-26 09:29:59] ?

[0ff]

You're right, sorry! Here's the one before the crash:

[2018-3-26 09:00:15] [FibaroHC2] didFinishLaunching. 

Also, here's somehting very interesting:

[2018-3-26 09:00:15] [FibaroHC2] Error getting data from Home Center:  null

Maybe it has to do with that?

[ilcato]

Yes, the plugin was not able, for some reason, to retrive the device list from Home Center on startup.

[ilcato]

I added a control and exit Homebridge automatically in this case. Will be available in the next release.
