Netatmo should be a good option although ifttt may prove to be a bit unreliable. In my experience local weather can vary greatly from forecast temperatures. Shame that something like netatmo and ifttt is the only option to allow outside temp influence evohome, this should be part of the product offering.
My netatmo will arrive next week and I've only bought it to add this important functionality to evohome. My boiler can turn the heating off at a predetermined outside temp but this could confuse the evohome system.
