A housewide offset both negative and positive which still follows the schedule would be extremely useful.

I do understand that a simple 'economy mode' might appeal to non-techie users, but they'd probably never go into the settings to tweak the parameter so it shouldn't affect usability.

Does everything just revert to set values, even if it was previously operating at a weather compensated mode?Resideo employee. Comments are personal, and likely to get a hard stare from Rameses

This proves that the Evohome controller can be programmed to add more OT command support and the OTG simply responds and relays them through. Previously I had seen no evidence that the External temperature was either requested or relayed between the boiler and the Evohome Controller via the OTG. So clearly this has been added in. In which case it should be quite easy to implement the boiler max command too, that is currently not set and causes the Viesmann to head for the stars.

re-enabled cold weather cold weather boost and Advanced Load Scaling yesterday (still have warm weather saver enable). Glorious sunshine today and house is like an oven this morning - how come as warm weather saver should have kicked in? Outside temp in the shade as read by my weather station is 14.2C Evohome showing temp as 9C !! This will be the downside as ideally evohome should support a remote temp sensor so it gets the local true temp not a remote generalised internet temp Nice idea though but once again have had to manually enable eco mode

Looks okay just now though: displays 10C, OpenTherm read value 10.74C and my Netatmo weather station 10.4C.

Anyone with an OTGW should be able to confirm this pretty easily. Just check for any OT commands referring to the Outside temperature being passed between the OTB and the boiler. Then just switch the home wifi off and see what the controller does before a Cold Boost zone switches on. Is it able to boost or ignores the boost.

Cold Weather Boost Suggestion
This cold weather boost needs some work.
I have sketched suggestion how I think it should work which would work good if possible, and allow user to calibrate to there house and there individual room if possible.
I definitely need a different SP differential, this morning I was boost and house was warm, very sunny outside but 9'C on evo touch screen. - 12 would be good to start boost at 0.5'C then we should have 2nd differential, lets say -18, then I would want to boost 2'C. The boost should be proportionally scaled between these to set points.
There should be 2 differential's and 2 boost SP's
The Differential SP's should be variable.
The boost SP's should be proportional to differential.
This would be awesome if possible and if could be done by individual room

Previously it would be in overrun.
