I’m seeing a consistent crash in the zigbee adaptor after a new version was downloaded during the night. At work, so can’t investigate.

I’m on it. 
I’ll get an update out in the morning.
Should be fixed in v0.12.1.
The fix seems good, thanks for the quick turn around!
It is not crashing 
, but the scene and battery properties on the Tradfri buttons disappeared 
. I’ll look into this as soon as I get some time.
@mrstegeman Please consider reverting this PR until the author(s) are ready to provide some additional revision and support.
In addition to the the issue that I reported regarding the scenes, two properties (On/Off, Level) are renamed to include the endpoint index in brackets. This renaming broke 36 rules in my setup.
For backward compatibility, the names on the first endpoint must not be renamed - I can understand that if there are multiple endpoints with an on/off property on each, then there needs to be a consistent way to separately identify them.
Please give v0.12.2 a try.
Thank-you @mrstegeman the property names have reverted to be without a suffix 
I’m still missing the scene property on the Ikea Remote Control - I’ll see what I can find. I’ll get a few hours here and there this week and should have more time next week.
Version 0.12.3 of the Zigbee addon just released (thank-you @mrstegeman) has fixes for the scene property of the Tradfri remote control.
Other changes include support for EQUALS in rules for scene properties, newly paired Zigbee devices will have better default names, containing the function (such as light) at the end instead of undefined, and a number of other cleanups.
