      With so much reliance on external temperature, I am still surprised that Evohome dropped support for a locally mounted external sensor. I used it and saw the benefit of being able to mount it where the temperature reading was the most "feels like". Also I now wonder what happens to all the weather compensation when the local weather feed breaks? Does everything just revert to set values, even if it was previously operating at a weather compensated mode?

        Yes, 3C is far too much, so I never use it. 0.5 - 3C in 0.5 steps would be pretty cool, both minus and plus, selectable at the time the quick action is activated.

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

          Massively so. I think it's the single best enhancement that has been suggested (and by many many people).

          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.

            If there is no feed yes it just reverts to normal control. The room temperature sp is always respected, it wont shut the system down if we are not within the temperature control tolerance. If you have an opentherm boiler with an outside temperature sensor input Evo will use that in preference to the weather data - just make sure it is positioned correctly - not always an easy thing with OTC

                That’s great that the boiler’s outdoor temperature sensor reading will be used! I’d assumed that control was just based on the Internet read temperature.

                  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

                      It would be good to confirm this, I still think the displayed temperature is read from the internet as I saw some earlier discrepancy.

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

                        I see Warm Weather Saver in action. I have one zone demanding 4% and the other 8% but with outdoor temperature of 10C the boiler pump is not running.

                        Previously it would be in overrun.

                          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

                              is there an easy way to spot its operating? I've switched off eco mode and immediately the rooms show as needing heat according to the main panel. Is the only way to spot its operational is to monitor the installer menu>boiler demand screen? Im a programmer and data architect and I am not a fan of "hidden features" as users always wonder if the "feature" is really working or not
