Does the Wiser Radiator Thermostat measure temperature the same way as a Wiser Room Thermostat? Follow
No. The Wiser Radiator Thermostat due to its location (next to a heat source) and design (when used without a room stat) is using its temperature sensor, but then applies an algorithm to estimate what the centre of the room temperature is, based on the above factors. This is the temperature you will see being reported in the app for whichever room the radiator thermostat is assigned to.
The main difference is that the Wiser Room Thermostat measures the actual temperature of a room, whereas the Wiser Radiator Thermostat gives an approximate temperature. If you find that a rWiser Radiator Thermostat is consistently too warm or cool compared to expectations, then the best resolution is to adjust the set-point (down if too warm or up if too cool).

Is it possible to "teach"or calibrate the radiator valves by putting the room thermostat in the same room for a number of days? This would be a nice function as equipping every room with a thermostat seems overkill, but the radiator sensed temperature does not seem accurate.
We are experiencing poor temperature accuracy in all the rooms that do not have the room thermostat when the outside temperature and wind changes. Knowing the limitations of the compensation algorithm it would be nice to have a simpler and less expensive room thermostat, a little box with no display and buttons that just reports the room temperature to the controller. I believe that this can be done quite easily using the electronics inside a radiator thermostat and put it in a room thermostat box like. Just remove the motor driver part and have a firmware with no predictive algorithm. This will improve the temperature control with an accessible cost for most households.
Given the room temperature can depend on a load of factors (Heating of room, height of ceilings, etc), is it possible ot add a "delta" mesurement. Ie we can say whatever temp the trv reads add 2C to it for the real value.
Currently I am finding the trvs in certain rooms are around 1.5-2C higher than the real temperature, this would enable us a little more control and keep the UI consistent with the real world.
As a workaround Im setting the trv temperature to 2C + which is fine but then the UI is also 2C out and the insights is a bit squewy
thanks, Wiser is the best!
Agree with the above comments.
We simply need a simple offset we can configure in the zone that the device(s) reside, that offsets the recorded temperature, e.g. +1.5c zone increase means if thermostats reads 20.5c, you see 22c in the app. If you set 22c in your zone schedule, it uses 20.5c when checking if demand is met.
Therefore, it doesn't matter if the zone contains smart radiator thermostat(s), room thermostats or combination of both, you offset the zone temperature rather than each device. This compensates for any factory tolerances and deviations between multiple thermostats in a zone. This should be simple to implement and not sure why it's not there already. Just about every other smart thermostat on the market has a temperature offset feature.
This is a real issue for us, customers. Overall, it's a good system, but we need to be able to tune that algorithm. As someone else mention before, a cheaper room thermostat would also work nicely. The one currently available a way too expensive for what it is.
