I think I may have found a boiler controller that could work for me - has anyone tried using this? https://www.amazon.co.uk/Secure-SSR302-Z-Wave-Channel-Actuator/dp/B00HZR6U7S
Looks like the search I was looking for was Z-Wave Boiler Actuator

Your right a lot of people have expressed concerns over the reliance on temperature sensors built-in to the smart TRVs. In particular vertical mounting ones are regarded as more likely to give erroneous figures than horizontal ones. I personal was always worried over ones combined with radiator covers.
Tado themselves claim the fact it has two sensors helps alleviate this, they also as standard have the ability to link one of their smart TRVs to one of their smart Thermostats and then the smart TRV uses that as an ‘external’ temperature sensor. Obviously this can add quite a bit of cost and some people have suggested to Tado that they offer a simple external temperature sensor.
It should be possible to use a generic temperature sensor and define a rule that says if temp above X then set smart TRV to off or a low value which would effectively result in off. However it would be impossible to do this as part of the Tado eco system, only by overriding its settings and schedules.
Remember the schedules when triggered will reset the temperature of the smart TRV back to what it was.
If you use Smartthings to directly turn the boiler off when a single TRV or room sensor reports the desired temperature then you ignore the highly likely possibility other rooms will not be at the desired temperature. You also probably negate the possibility of benefiting from ‘modulating control’ of the boiler since you are forcing it to be on/off. Modulated control of a boiler is supposed to generate energy savings of around 5% on top of savings from geo control and more efficient scheduling. It is also supposed to make rooms more comfortable as temperatures will be more even.
I cannot see Smartthings or similar being clever enough to define a rule which is going to need to be equivalent to a whole bunch of ANDs i.e. IF room 1 AND room 2 AND room 3 are warm enough THEN turn off boiler.
If you only have temperature sensors in each room and a means to turn the boiler on/off then some rooms will end up too warm and some too cold. This is what smart TRVs solve.
It will likely not end up being much different to Tado but have you looked at Drayton Wiser? This is their smart system and there is an app to integrate to Smartthings discussed in these forums.
I have Evohome with 11 zones. I have recently integrated it with Smartthings so that the system switches to Eco mode for X hours when everyone has left the house on weekday mornings; and getting notifications & emails on mode changes (Eco/Auto/Off).
I will be setting up door and window sensors to trigger “windows open mode” for some zones.
How on earth did you connect it to smartthings?? There is no official hadler…
Hello, Black-Paladin:
I am somewhat late to this party but I too have a Genius Hub System, which I’ve had since 2015. I have (right now) a hub, an electric switch (to turn on/off the radiator pump), 2 smart plugs, 4 TRVs, 2 thermostats, and 2 room sensors. I also have (still in the box) 4 more TRVs which I am awaiting a plumber to install the correct valves on four more of my radiators - after the pandemic.
I haven’t been terribly happy with the system, in fact the heat came on this afternoon with everything turned off! It took the company about an hour to fix it and the house is relatively cool again!
Here’s why I’m writing: I am told that my z-wave signal is weak (I guess the smart plugs aren’t smart enough) and the only signal extender is intended for use in hotels - they are permanently wired in. I wanted to know if anyone with this system has tried any of the extenders on the market that simply plug in to a power point and, I guess, work just like a wi-fi extender?
I would be most appreciative of any relevant information anyone has.
Thank you in advance.

Hi @TheArtfulDodger.
First off, apologies for very belated response, I dropped off the forum for many months for to pressure of work but am now catching up.
I have to say, my Heat Genius system has been working flawlessly. I have 5 of their smart switches though so if you are still having problems (I hope you are all sorted by now) then maybe it is a z-wave network strength issue.
I use a couple of z-wave extenders for my SmartThings z-wave network (which is a different network to the Heat Genius network in case you didn’t know) but only use the Heat Genius Smart Plugs on that network. Did you try one or two more of those? Good placement matters too of course.
