I have an Evohome that has pretty much behaved until now. I have firmware version and wanted to set the Warm Weather Saver but it was missing from the menu. So was Cold Weather Boost. I remember form the Beta that these options appear/disappear if the location was not known and it showed until sometime this week. I have only the network in the top left. I have disconnected and reconnected the wifi on the controlled, rebooted my router and deleted and added my location on the Evohome website. Still no outdoor temperature and so no warm/cold weather options. My address has not changed and the postcode is still on the account.
