I find that mostly my real outside temperature measured by my own sensor is within a degree of “internet” obtained temperatures. Currently my outside temperature is 4C. Dark Sky says it is 6C and Evohome says it is 5C. It should be an easy job to use a wireless outdoor sensor which talks to the Evohome Control Panel. After all that is what my outside sensor is doing - it sends readings into HomeKit and the Hue app, which reminds me, it is high time, very high time, that the Evohome app worked with HomeKit.

So if you have cold weather boost set to a 10C differential and enabled on a zone with a 21C set point and the outside temperature goes below 11C it will become active for that zone and apply the configured boost offset.
Since it's based on a differential between zone set points and outside temperature and not absolute outside temperature cold weather boost can be applying to some zones and not others if they have different set points.

Today, Sunday 20th at 11pm, the outside temperature is reported by my external thermometer as a stable 8 deg. Alexa reports 6 deg, Evotouch reports 6 deg, Evohome App reports 8 deg and iPhone says 8 deg. Weather is clear and sunny with little wind. In my location it appears that you would have to assume that the internet data can regularly be 2 deg from actual. I don’t know how relevant that would be for the operation of temperature compensation.
My external thermometer is away from any sunshine and completely sheltered from the wind on a North facing garage wall that does not get any heat from the house.

The impact of 2 deg on FULL load scaling is pretty minimal, so I wouldn't be overly concerned there - really it's if the temperatures were out by closer to 10 deg you'd start to see a negative impact.
Do you know how the Evo reported temperature compares to Accuweather's temperature for the same time?

Outside thermometer 10 deg C
Evotouch 6 deg C
EvoHome App 7 deg C
Amazon Alexa 6 deg C
IPhone 8 deg C (Weather.com?)
Accuweather 6 deg C
BBC weather 8 deg C
Don’t know if any of that helps.
