Ideally the outside temp used would be a 'feels like' temperature, as that includes wind chill (which chills houses as much as it chills people). Much better than just using a normal 'weather station' type value.

No, that's discussion about whether per-zone enabling of optimal start will ever come back.Quote:

A little disapointing but not unexpected, but it can be worked around with additional set points. (Assuming you have any free set point slots in a zone)
Actually, this was exactly what I was thinking. Last night EvoHome increased me zone temps as it was colder outside, but..it was completely still and didn't feel cold. I tend to find that my house gets cold when it's wet with wind outside. Again, in the dead of winter with snow outside and no wind, the house feels fine.Quote:

Do the zones in question have remote sensors or just rely on the HR92's sensor ?Quote:

Have to say the Cold Weather boost here too isn't working well, finding the 10oc outside set point is too high for the Cold Weather Boost to kick in and is boosting zone unnecessarily. Needs to probably be more like 5oc for me....
Panel is reporting 10oc, local weather is saying 11 and my own sensor saying 12 outside too which isn't helping.
How low the outside temperature needs to be before a boost is appropriate is going to depend on many factors including insulation in the house - the threshold temperature differential probably needs to be adjustable in the settings to make it useful..Quote:

I agree the -10'C below setpoint may not be good for all, depending on individual room thermal insulation. I think this needs to be variable and variable by the room. Also some saying it should take in windchill(feel like temperature), I agree with that.
For my living room where I am sat now, its boosting 0.5'C, that is ok with me. 19C SP outside temp 9C so actual setpoint is boosting to 19.5'C
Other rooms in my house which have better thermal properties or worse, I would like to lower or raise the differential for boosting.
Its a improvement.
You're quite correct, I had misread/misunderstood that point. That's why i'm finding it behaving oddly - I have my set points quite high, 21,22,23 in different areas. Knowing that now, yes ideally the -10oc difference needs to be variable, maybe not by room but at least as a system whole.Quote:

I have seen random changes to 30 degrees on the old firmware on my system, although not recently. I even documented it on a thread here.Quote:
