Due to ongoing debates about the use and misuse of the “German Support” category to the detriment of users who don’t speak German, the creation of new topics on the category has been closed. Thus, this category is now read-only.
I may have finally found the cause of my crazy playing LED. It seems to have been my mqtt broker. For several reasons I installed a new mosquitto on a Proxmox drive. Unfortunately this meant that I had to change all IPs in the config (about 2700 lines). A bad job.
But since I did this mqtt move, the LED problem is gone. I guess there was a “retain” problem in the old broker. But I guess only.
