Have you tried restoring your backup from 2023.12.x to see if the problem truly is gone in that version and it’s not something else like a chattering device, wifi interference or something else?
Didn’t try this one.
Although I have a backup as per standard upgrade procedure, I have no experience with such rollback process…
I’ve to well prepare myself for this first !
Anythink else to help investigating ? Like activating more tracing…
Restoring is simple, just get a backup of where you are right now and restore that one for a test and then you can restore your current version back. This at least will tell you if it might be an issue in a new release or if it’s something on your end.
Back to share outcome of this issue.
The problem was NOT due to 2024.1.x.
The zigbee network seemed to be put into trouble by the sonoff coordinator or some corruption in the zigbee setup (honestly not 100% sure).
Finally I replaced the Sonoff device by skyconnect : everything now runs very smoothly since more than 1 week.
