@marzipan71 Ah yes.....I see you've given this a lot of thought.  10 year olds leave lights on too, or mine did.

Ah - you just hit on a problem - the boy has a switch in his bathroom for the recirc pump - on is no problem, but turning it off is another matter entirely. Motion sensors in the shower cubicle!

That will probably help but does of course mean that the water which was piping hot at the top is returned to the top slightly cooler, as a result of being circulated.

It did cross my mind but I'm trying to ignore that so please don't remind me 🤣  Hopefully the loss will be very small.  I will try it once the house if finished, but that is a long way off.

My ramblings about the shower valve being wifi connected - you made me think @johnnyb that it might be possible to install a switch either in a spare slot in my wall switch or a wireless switch that could tell a digital timer (rather than the mechancial timer I currently have) to swtich on or off. Would need one in my son's bathroom also. I'm not in any way electrical so not sure if that exists but my experience is that if you can imagine something wifi or smart, it probably exists.

That is what I was wondering about as well. My son's are old enough to think about switching the pump on if I make it simple for them and the water runs hotter.  Reading the first page I see that @ubert767 included a link to a switch at toolstation that does what we want, and if I understand it correctly there can be several switches connected to one receiver, so one in each bathroom shouldn't be a problem
