Rated 4 out of 5 by from Could be better The smart valves are quite good. The app is very basic compared to others on the market, other apps have an overview of temperatures, with the TCP app you have a list of rooms with no information, you have to go into each room to see the temperatures which is very annoying. Another annoying problem is when you change the temperature with the app sometimes it will change and sometimes it wont, and your spending more time than necessary double checking not good. I installed these throughout the house and it is saving me about 15 units a week of gas which is brilliant and that's down from 37 units a week, these will save you money by just keeping the rooms you use the most warm.

Rated 5 out of 5 by from Love these TRV’s I now have 7 of these installed and love them. No more guesswork as to what the temperature in each room is. Looking forward to a smaller gas bill too

Do you need to use the TCP hub in order to control with Alexa?

Asked by: WhyShouldINeedANickname
I'm investigating these devices and have found a manual by Googling "TCP-Smart-Instructions-Quick-Start-Home-Living-Radiator-Valve.pdf". It seems from this that you MUST have a TCP Smart hub for this device to work with Alexa or anything else. You only need one TCP Smart Hub per household which will support many valves. The valve has to be in range of a WiFi access point, and the WIFi has to operate on 2.4GHz band - this shouldn't be a problem.

Temperature Range and Sensitivity?

Specification shows temperature range 5 to 15 C - too low for most applications. Picture shows 25 C! What is the range? What is the sensitivity - 0.5 C, 1 C - some are plus or minus 2 C - a 4 degree range. What is the tolerance on this TRV?

I'm investigating these devices and have found a manual by Googling "TCP-Smart-Instructions-Quick-Start-Home-Living-Radiator-Valve.pdf". It seems from this that the range is 5 deg to 35 deg. The range 5 to 15 degrees is Eco mode which is to stop freezing when you are out of the house for long periods.

What adaptor does this come with?

I need to replace an old Drayton TRV head with a 28mm thread (not current TRV4 head) Will this fit it? Thanks

Hello Screwfix, are you able to answer any of these questions?

Asked by: benbb

Do you need to have the hub to use the thermostat valve or does it work on its own ?
