Basically creates a virtual thermostat driver that makes IFTTT calls to perform actions on your thermostat. Since there is no baked-in support for Honeywell, this seems to be the most reliable option since you have to use the cloud either way. If you have questions/comments let me know. It's really lame you have to create 7 webhooks per thermostat, but I see it as a win for being able to do more robust things in RM.
If you want native thermostat support, give this a try; keep in mind since Honeywell doesn't support this method, it may not work forever. Also, set poll times to be 30 min or greater.
