TRV active when system off (Frost Protection)

edited August 29 in Technical Questions

I’ve recently installed Tado and have TRV’s, two in one bedroom and one in another bedroom. The weather’s warm so everything is switched off (frost protection).

The other night, about 03:30 all three TRV’s performed a couple of rotations which woke us all.

What would cause this?

I thought maybe it was a temporary loss of connectivity but I tried switching off the Internet Bridge and the house Internet but this failed to cause the TRV’s to activate.

Firmware update maybe?

    @Markflow the radiator thermostats will recalibrate themselves after a firmware update. I know they've recently received a new update, mine updated to 90.1 just the other day, so it seems likely that's all it was.

    That being said, I was under the impression that tado forced updates during the day to avoid noise in the night, but can't remember if that was an opinion I read somewhere or if it was direct from a tado employee on this forum...
  • Thanks for your feedback. Maybe Tado should allow users to decide when to apply updates (like Hue)?
