This is an API for Honeywell Lyric T6. The idea is based on Remco B's version for the Honeywell Evo.
Using a virtual device with API scene, you can change setpoint and set away, holiday and schedule modes. Because it is a virtual device, you can call these buttons from any other scene. For example I use it while tracking my phones location, this creates options for GeofenceMode in combination with ScheduleMode
You will need a webserver (or access to a webserver) for the initial setup. This is to retrieve some keys from Honeywell. As soon as you have the keys, you do not need the webserver anymore. For further details please follow instruction in the pdf and use at own risk.
release 1.1 added checkCertificate option to bypass https check.
