Grouped lights turn back on after a few seconds

Hello,

recently I’ve noticed that when I turn off a switch that communicates to a group of lights, the latter turn back ON after a few seconds.

Does anyone have a clue what could be the culprit here?

Here is what I have:
-3 zigbee lights grouped as one in a yaml file. The zigbee bridge is a Nortek stick.
-1 switch (shelly) that operates said group of lights through an automation

happy to provide more info if needed. Thanks

Anyone?

Even after the update to 2022.4.1 and removing the group description from yaml and using one of those new helpers, the problem persists.

Thanks to who would try to help
