I'm intrigued as to the improvement this yields - surely it's altering the 'charge time', based purely on the room temperature at the time it's charging (i.e the middle of the night)? This is what my XLS24N does (albeit using a mechanical thermostat, positioned in a stupid place).
But what you really need, is to be able to set the 'charge time', based on a temperature at some other point in time. Ideally, this 'point' would be sometime tomorrow(!), but maybe the previous minimum, or average of the previous cycle would be better than nothing. Also, if the heater is only going to be on for (say) 3 hours, you'd want those to be the last 3 hours of the economy 7 period, rather than the first 3.
I've rather given up on improving the XLS24N - it has two shortcomings. 1) is the inability to keep the heat in, until I want to release it (the insulation is not good enough) and 2) the inability to get the heat out fast enough, when I demand it (no fan). (I do have a piece of bent metal, that can be inserted to lift the internal flap, when the heater doesn't otherwise want to cooperate )
Wrt to wireless thermostats in general though, I agree they're like hen's teeth. I couldn't find any (at reasonable prices) to control my wall-mounted convectors - so I used Picaxe 14M2's, talking to commercial (Energenie) RF sockets. Every house should have a heating system controlled by 10 Picaxes
