The web-based integration service If This Then That, which is trying to tie your physical connected devices to your digital services (and everything to each other), now supports the Nest thermostat. Or rather the Nest thermostat, which is the subject of a new open developer program, now supports IFTTT. So now readers could geo-fence their Nest to their phones, change their temps based on incoming emails (your ex sends an email the temp drops 30 degrees!) or whatever other recipes you’d like. Yes, all this will likely be available via the Nest developer program, but IFTTT is a way to bring in devices that may not yet be supported.
