Youtube on Samsung TV messes up my esphome shellys

Ok, I am at a total loss here…
Since this morning whenever I start youtube on my samsung Qled tv lights start turning on. Youtube also takes a long time to load and the longer I wait the more lights turn on (because somehow HA thinks the state of the button connected to the esphome-shelly switched state.
I figured a possible ip conflict, but restarted all my devices.

No idea where to look for. It seems only the shellys are affected as all my esphome lights themselves do not change state…

edit: it seems all my esphome devices become unavailable, coming back online it’s seen as a state change hence the lights go on.

However still no idea what happens so all my esphome devices (40+) behave like this

Is youtube saturating your wifi network so all the other devices can’t connect?

Oh wow… figured it out… after turning off some fuses to work on my electrical circuit somehow my tv kept connecting to my unifi in the electrical cabinet instead of the living room.
Still no clue why it only affected the youtube app and not amazon/netflix/apple tv+ and why it messed up my esphome devices though…
