Laggy outdoor temperature strikes again tonight.
For the last few days I've been using cold weather boost to boost the living room and dining room 0.5C with low outside temperatures and it has been working quite nicely actually, boosting the temperature slightly just at the right time as the night starts to set in and reducing it slightly during the day to avoid the rooms getting too hot with direct sunlight.
However tonight we noticed the living room feels a bit cold and on checking the cold weather boost hasn't kicked in, even as of 9:30pm.
Actual outdoor temperature according to my weather station is 8.3C, Weather Pro (Meteogroup) on my iPhone reports 7C, the iPhone's built in weather app reports 8C, weather.com reports 8C, even the weather report in the Honeywell TCC app reports 8C, however the reported outdoor temperature on the Evotouch still says 12C, which is too high for cold weather boost to kick in.
According to my temperature graphs the temperature dropped below 12C about 5 hours ago, so the reading on the Evotouch is either stuck or about 5 hours behind. Is there any particular reason why the outdoor temperature is lagging so much today ? It's a shame because the cold weather boost function is actually useful, but only if the outdoor temperature reading doesn't lag too far behind actual conditions.
I wonder if the controller polls directly from the weather service or pulls the data indirectly via Honeywell servers ? My guess is the latter.
Edit: naturally, as I wrote this post the outdoor reading on the Evotouch dropped to 10C and cold weather boost kicked in. However it is still 2 degrees out from actual and 3 degrees out from all the other weather services I checked against. If it's lag, it's still lagging by about 3 hours even after updating.
