Is there really a need....
…to have more than one smart TRV in any room? One of mine went belly-up today and I immediately thought of replacement and then thought twice! At the moment it's without a 'head' but may well re-fit a manual one if the need arises.

……given the response (!!) it looks as though I am the only idiot who has fitted multiples. Quite looking forward now to fitting a manual head with its considerably finer tuning enabling a better balance across the whole room methinks.

@samd Our upstairs landing has two identical rads with two TRVs and the room temperature is well balanced. Let us know how you get on.

I have two rooms which have two TRVs driven by wireless temperature sensors. Previously I didn't have the latter but working this way has improved temperature consistently . . .

I should have mentioned that the room is controlled by a Wireless temp sensor which, of course will call for heat. My role is to mess about with the manual setting on rad 2 just as we would have done in the old days when buying a new house! Couple of days fun next autumn. You'll have to wait till then for me to come back crying cos I'm not wasting heat in our wonderful British summer!!
I should add that my 'reasoning' has been fuelled by my almost certain knowledge that in all the years of having this set up, I have never witnessed the 2 rads working at different output levels. They both have under-rad mains-powered fans the sound of which changes on output.

What I meant by 2nd para above is that neither of my rads would reduce output were the occasion to arise in which one part of the room (and rad) was equal to/above target temperature. They would carry on at same output until the measuring device declares otherwise on behalf of the whole room. So they are not smart really once under a measuring device.

@SteveIreland Useful thanks.
I had written a very complete response off line explaining my somewhat unique setup only to discover that the belly-up device is now working again. Suffice it to say that I would have needed to turn off the manual control every evening before bed and re-set before use on schedule something an 82 year old retiree could have managed OK. I like playing with kit!

If you do need to replace then better to just buy their basic TRV since you're already using a wireless temp sensor
Without a TRV on the rad, it would keep pumping out heat into the room if other rooms are calling for heat. I think this would mess up the thermostat's learning
