yes, weather compensation is the same as ODR. All new condensing boilers come with it or the thermister is an option.
They do not, as a rule, measure the indoor temps but it is an option to do it. I have a Viessmann boiler with ODR control and no internal t-stat. The wife hates it but it always maintains the desired temp in the house. Mine has setback schedules as well but I don't use them with high mass radiant.
The first company on this side of the pond to really do anything with them is Tekmar and they still the leader in resi aftermarket controls.
My control on the boiler is set to raise up 0.8C for every 1C drop in outdoor temp (typical starting at 20c but I start it at 16C outdoor temp.)
I've been putting them in for 20+ years.
