Fun, fun, fun! Woke in the night to the bedroom light dimming and brightening on its own. Interestingly, it's not wired to a dimmer switch, just an old-fashioned on/off toggle. And, although it's a dimmable LED bulb, it was switched off at the wall…
A little later, everything went off. It seems house lighting circuit is tripping RCD for everything in the house.
I've disconn'd every light at the switch - no change. Msg left for electrician…
