Lightify come on and stay on after internet disconnection blip

For some reason, not sure if its the internet or the power line adapters that my ST hub connects to my Apple Time capsule, to my router, but I get notification saying ST hub s disconnected from internet, then maybe few mins later, its connected. I suspect power line adapters tbh.

So when this happens my Lightfy bulbs stay on, even though I have setup if no motion after 10mins to go off, but they dont. I have to manually switch off in the ST app and then they work again.

Anything in ST I can do, routine, etc, or do I have to sort the power line adapters if those?
