The system learns the pre-heat time for each zone. Do you not find that your zones with oversized rads start heating later, and the others earlier? I find it works really well.Originally Posted by SteveP
For me I have a few rads that are oversized and only need to start up to produce a comfortable warmth and so i don't want optimisation, and then have a few rooms that take longer to heat (Mainly bathrooms with towel rads) and so benefit from optimisation. When I had the non-wifi version with individual optimisation that supported the scenario. Now with the "upgraded" wifi version I effectively have to mentally alter the oversized rads schedule to compensate for the optimisation I need for the undersized !! I would love individual optimisation to be brought back
The optimisation does adjust but as they are bedrooms they wake us up due to the noise in the pipes and the heat - find it better to just turnon the rads just before getting up say 15 mins. With optimisation they can start up to an hour earlier because the undersized rads need an hour optimisation maximum window.
@DBMandrake, I have purged a good pile, can you try again please

Just curious but with the weather now all over the place in terms of evohome recorded outside temperature vs the "feel" temperature and the variability day by day and during the day, how are people using these new features? I've ended up turning them off and reverting to the suggested "custom / summer" setting leaving out the bathroom zones to keep those towels toastyseems to be working a treat at this moment. Today the outside temp is showing as 7c and yet it feels sooo pleasant outside and no heating required. I am not saying these new features are not potentially beneficial but wonder if they just solve a problem that we didn't know we had or a problem that is so personal, no automated solution can 100% satisfy everyone? I do though worry as DBMandrake commented that there are new features that are so deeply embedded and result in curious system behaviour that a user may believe is the system at fault. Whilst I like the system to "help me" if I want heat then I WANT HEAT! I don't want the system saying "well you don't really need heat so I will override the user" - lol. Not knocking the enhancements but as a software designer/developer am wondering if the changes are a "step too far"?

I guess many people on this forum have a technical bent and many have considerable experience in system design and implementation. I’m essentially just an observer in this process as I have the non-wifi model that satisfies my requirements very well. Optimisation works brilliantly in my experience and I appreciate being able to tie into IFTTT for geofencing.
I’m not fully conversant with the differences between my version of the controller and the current version but I haven’t seen anything in this thread that would make me want to upgrade. In particular, I’d have misgivings with a system that used an Internet temperature source as a component in its operation, living, as I do, in a village that encompasses a flat plateau and a deep valley.
It seems to me that Honeywell have a problem with this product in that they can’t decide whether to market it to end users (as many of their current competitors do), or to the trade.
With the changes being incorporated, quite apart from the perceived system faults that DBMandrake and SteveP have mentioned, this will add to the marketing challenges as any likely adoptee is going to want to know in some detail how it works.
And it's just got a lot more complicated.
Although I am not using the beta version I could not support the statement “optimisation works brilliantly in my experience” for my experience after many years use has always been that it never seemed to learn a room, always came on far too early, so I abandoned it and used a schedule setting which in my case is more efficient, economical and effective.
And hence why if a per zone Optimisation was still possible, then its usefulness would have been so much better. Even if was not perfect, I wouldn't mind the heating coming on a bit earlier in certain rooms. I would absolutely not want it coming on earlier in the entire house. This for me is the single biggest backward step from moving up from the non WiFi to the WiFi models. Believe it or not, even today, I recommend the non WiFi panel to people because so far there is absolutely nothing that the WiFi model does that is genuinely better.
I come back to the point. Evohome is a zoning product. So features should allow zones to be treated as such.
I have to agree with peterf and bruce_miranda. If I had not found this forum, I would have been pestering my installer with a lot of questions at the beginning. As it was, I was able to give him some tips found here, even though mine was the 5th system he had installed, including his own. My system was installed soon after the switch to the wifi controller, I am beginning to envy those with the previous version. I am not in the trial as I do not want, or need, many of the existing “smart” features and the current system already confuses the rest of the family because they do not want to spend hours researching it’s foibles. I do not have any experience of other smart systems, but could only recommend EvoHome for the tech savvy who need completely independent zone control. A rather limited customer base.
Maybe it would work better if I lived to a very structured organised schedule and only used one heat source, then I could have got the installer to set it up and just left it alone? Although even the I would have to pay for a regular visit to get the controller batteries to charge properly etc.
I am contemplating disconnecting it from wifi to avoid this so called upgrade, but then I would be forced to use the horrible unresponsive touch screen rather than the app and could not turn the system on remotely when on my way home after being out on a cold day. In the end I will probably have to operate the HW manually to minimise interference with the heating.
Yesterday morning EvoHome was reporting a temperature 3 degrees below the actual outside temperature and 1 degree below that reported by my Alexa. At lunch time today they all agree. I do not see how this can be the basis of an acurate control system.
Hey, what goes on here, I spent 20 minutes yesterday replying to this and explaining the operation.
But it's late and it's been a very long day, so for now... no we dont base temperature control on this weather data. I will explain more when I'm less fed up.
