Thanks for taking your time to help!
I´ve played around with changing on / off and dim values countless times when troubleshooting. Sometimes this works, ie device state and / or dim value gets updated on the broker, sometimes it doesn´t. I have failed to detect any kind of pattern. It could be “any device” at “any time” that doesn´t get updated. Basically the only thing all have in common is that none gets updated when broadcasting. On app version 2.0.2 I never had this problem.
One thing that puzzles me is that I occasionally get different kinds of [getaddrinfo ENOTFOUND localhost localhost 80] warnings when broadcasting or viewing log tab in hub app. Usually this causes Homey app to crash, thus requiring a full Homey restart from developer site or pull the plug. An example below:
Also nordic letters never seemed to be a problem on 2.0.2. I would ofcourse consider changing name on my devices to only english characters if that helps. But since that would reduce the family friendliness of the home automation, it´s more of a last resort.
