Error with Yeelights

[kiwikern]

I've added a couple of different Yeelight devices (color bulb, white bulb, desk lamp).
With all of them, I experience the same behavior: Triggering an action results in at least five 'DONE' toast messages, but turning the lamps on/off works. When changing either color or brightness, the controls wildly change (turning on/off several times etc.) until this error message appears:

error [pimatic]: An uncaught exception occurred: TypeError: Cannot read property 'location' of undefined

 This is most probably a bug in pimatic or in a module, please report it!

Switching to the v0.9.x branch using these instructions and creating the devices (for the yeelights) manually via the config resolved the issue. (sorry!)

Unfortunately, the error still occurs after the update.
