Possibly size of the house is a key component here, lol. My miniature 60sqm probably not a good barometer.
That is not at all how what thermostats work.Do you not have normal TRVs on your radiators already? Just set them to 3/4, or look up the manual for your TRVs and see what temperature the 1-6 values represent. All smart thermostats do is the same thing but let you control it on your phone, it's a lot of money for that 'convenience'.
Would the cost of replacing your TRVs in all of your rooms really save you that much money?
Example for TRVs:

And the manual:

2 - 12C
3 - 16C
4 - 20C
5 - 23C
6 - 26C
I suppose the benefit the smart ones give is that you could lower the temperature at certain times and increase them at others all automatically, whereas the old TRVs will be constant unless you get off your bum and change them all. Depends on your use case for certain rooms, that you want them to be warmer at certain times of the day or not.
They still don't seem like a 'save you money' piece of technology, rather a 'quality of life' piece of technology.

To say they are the same as normal TRVs asked how little you understand.
Normal TRV controls the temperature when the heating is on by the main thermostat.
Smart TRV is a thermostat and has full control of your boiler.
Mine has paid for itself and continues to save me a lot of money.
Are you talking about rad TRVs or thermostats? TRVs control whether a radiator valve is open or closed based on the temperature in proximity to that radiator. Thermostats usually turn the whole heating system on or off at certain periods of the day that you program, and also override the on/off based on set temperatures in proximity to the thermostat. Even if your smart TRV is capable of turning on/off your whole heating system, whether or not that’s efficient depends on how your CH runs were set up in the first place, and/or whether you have smart TRVs everywhere. Altering your CH runs to zones and/or replacing all your TRVs with smart ones is not cheap!That is not at all how what thermostats work.

For instance the wife is at home all day so we have just the living room heating on.All the going away for holidays/weekends you can solve by just setting your central thermostat down or off completely (or frost protection).
Having a smart thermostat I think can be worthwhile (I have one, although it was an Xmas present), TRVs, I just don’t see it personally. But like I said if you’ve got a very large house, and your CH loops are set up with them in mind (and/or zones) then I can see how they could be effective. But in the vast majority of peoples homes, I doubt they would offer a good ROI, over any sensible period of time.
He's got it in his head that it's not for him but that we're wrong. No point in trying to convince him.For instance the wife is at home all day so we have just the living room heating on.
Then at bedtime the downstairs rooms turn off and the bedrooms are set to around 15c.
The babies room is set to 18c.
At weekend we also heat up the dining room as well as the living room.
You can't have that control with standard TRVs. It's saved me a fortune only heating the rooms I need to. It all makes use of opentherm as well for extra high efficient boiler use as during winter for instance the boiler runs almost constantly never cycling on and off.
The opposite use case is our main one. In winter when the little ones room drops below 17.5 it turns on the heating till it hits 19. No other room heats unless they're below their targets.All the going away for holidays/weekends you can solve by just setting your central thermostat down or off completely (or frost protection).

Yeah I'm getting that feeling.He's got it in his head that it's not for him but that we're wrong. No point in trying to convince him.
I think your missing my point!
I'm not disagreeing with what you say about the cost of these and how long it will take for them to pay for themselves, and at no point have I disputed that.
Smart TRV's will ultimately use less energy than standard TRV's (unless you adjust them manually on a daily basis).
You saying they are nothing more than for convenience, may well be your opinion. But it's factually incorrect.
Some rooms I keep mine on low setting all the time that I don’t go in often.
The bit where you say 'Saved me a fortune heating the rooms I need to' - thats the bit I'm looking to find answers or someone to explain if by having the boiler turn on will save money in the long run.For instance the wife is at home all day so we have just the living room heating on.
Then at bedtime the downstairs rooms turn off and the bedrooms are set to around 15c.
The babies room is set to 18c.

No. It's about losses. If each room is capable of losing an amount of heat and you only pump heat into one of them the losses are reduced. Simple as that.The bit where you say 'Saved me a fortune heating the rooms I need to' - thats the bit I'm looking to find answers or someone to explain if by having the boiler turn on will save money in the long run.
What I want to know, turning on the boiler to heat certain rooms will cost less than turning on the boiler to heat up the whole house?
Is it that those radiators are quicker to get warm to bring certain rooms up to temp ?
