What happens when you press the broadcast button in the MQTT hub settings?
Sorry for the late reply. Been a bit busy.
Just pushing broadcast in the mqtt hub does exactly what is expected, it triggers a broadcast and updates all selected devices. Nothing strange here.
As it seems it only happens when homey is rebooted or when my NAS is rebooted.
Will do some further testing when I have the time to see which exact app and/or docker container causes the strange behavior.
This solved those kind of problems here:
After implementing the above settings (and changing all topics in the dashboard) my problem still exists.
Yesterday is was able to narrow it down to the application giving the error.
After restarting the Mosquitto MQTT docker container, all my lights flicker, thermostat is turned off and alarm is activated.
Creating a debug in Node-red didn’t give any result, because the Mosquitto server is restarting, no topics are received in nodered during the restart.
This conclusion exludes nodered from causing the problem, so i will have to investigate what happens within Homey after a restart of Mosquitto.
Anyone knows if there any way to create a debug log in Homey?
You can install the app by CLI, and then run
homey app run
Then you can see the debug output in the cmd screen.
How to CLI:

You can add a debug node in Node -red to see all messages coming in. That might be helpful narrowing down the problem:
The Homey MQTT Hub has also a log, but I don’t think it could solve your problem:
The Homey MQTT Client has also a log:
(All in the app settings)

@Peter_Kawa @Satoer Thank you Peter and Michel,
Already found the log in the mqtt client.
Will try to narrow down the issue with teh loggings in Homey when i get back from work.
Thanks in advance for the support!

Controlling the color of philips hue lights: It seems like a pain in the ass.
I have no idea if someone already solved it. I searched through the replies but i was unable to find it so i sat down and tried to come up with a solution.
I wanted to control 4 color spots that i have. Meaning, turning them on and off but also changing the color. And i found a solution 
This is what i came up with.
