Random lighting level

In my Homey Pro setup, my entire lighting in the house i consolidated in a Philips Hue bridge, managed by the Homey.

At random times, sometimes a few times during a day, other times days inbetween, lights are loweredd to minimum level (appr. 10%) - all over the house at the same time.

Lights can then be reset to preset value by double-tap on the corresponding switch or in the app.

This is an old issue by now, and I have asked about it before with no resolution, so fingers crossed.

Hi, can you add a link to the previous post?
So we can skip the questions already asked.

First I’d like to advice for you to install Audit app.
This app logs every move Homey makes.

Thank You for the input.

I have now installed the Audit app.

What am I looking for - a message or detail, and at what level?

It kind of works around the problem, but doesn’t really fix it, but thnak you for the input.

I actually had the same problem a while back. In my case it was a Hue Motion sensor thar caused the problem. Whenever the Hue Motion Sensor was activated/deactivated it took approx 4 minutes and all my Hue lights dimmed down to 0%. It started with 2 Hue-lights, but in the end all Hue-lights where affected. This is not a Homey-problem, but a Hue Bridge problem. I resolved it by removing the Hue Motion sensor from the Hue Bridge (and Homey) and exchanged it into a Z-Wave sensor directly to Homey.

Yeah when you know at what time strange things happen, you can check the log file entries and look for the lines with matching timestamps, in order to find possible explanations for the ghost events.

In the app settings / app configuration, you can temporary select “Debug” level. This records the most events possible, but generates biiiiiigg files as well. Select “Info” or “Notice” when there’s nothing to troubleshoot.


It creates a log file each day. This file can be downloaded by longpressing / clicking the file name of today, or yesterday or earlier dates.
What’s in there? Something like:
