Smart Thermostats Hysteresis

I have just installed a Hive smart thermostat, and I have noticed there is next to no hysteresis in the system. For example, if I set it at 20 degrees, it will heat to 20.1, then as soon as it hits 19.9 it will fire up the boiler again. 

It is keeping the temperature I want, but the hysteresis on it is far too tight. For context, I have an older Victorian house, and it loses that heat in no time. This results in short cycling of my boiler, particularly at night when it is colder (set to around 15.5 as I have a small child). I have spoken to Hive, and there is no way to adjust this, I should probably have worked this out before I bought it, but honestly I thought it would be similar to my previous thermostat in terms of hysteresis.

My previous Boss Therm thermostat would heat to 0.5 above target temp and switch on again at 1 degree below, which worked well. I wanted something that replicates this that I could set a schedule and switch on/off when I was out of the house. 

Does anyone recommend a smart thermostat where the hysteresis can be adjusted? I have found Netatmo which seems to allow this, does anyone have any experience with this?

Nest is reported to be 1 degree but again isn't user controllable, some say its too much others not enough. 

Echobee does allow you to set it but they are US centric and designed for central air systems not radiators etc

I think this is a flaw with the Hive controllers, there is no means to prevent short cycling.

I've got Wiser, and that also basically has no hysteresis either, although it does only fire up several times an hour unless there is large demand so usually prevents short cycles, still annoying there is no setting for it

My nest is 1c. It was 0.5c on my old danfoss which I felt was about right. Maybe the OP has a boiler setting to prevent short cycles cycling.

Several times an hour seems like a lot to me. I'd rather the boiler ran for longer and was off for longer so that it was more efficient.
