Zoe,
I recently purchased the new Prestige 2.0 IAQ thermostat and I have to say that so far I am really loving it. In the coming weeks I will be purchasing the Redlink gateway for the app support. After watching some basic furnace operation videos on Youtube I found that installation was a breeze and I'm already seeing savings on my heating bills due to the increased accuracy of the thermostat, independent fan control, advanced scheduling, and additional sensors.
I chose it over Nest because of the press release announcing the Comfort Control API. Please add my voice to the growing roar of people asking that this not be a completely cloud based API. I find it discomforting (pun intended) that a device installed at my home and the accompanying data will only be accessible via the cloud. I am also concerned about privacy of this data, that Honeywell will inevitably profit from the gleamed meta-data that is provided by default because of the nature of cloud based computing, and the inherit trust we must place in Honeywell by granting them external control of our equipment in a system that we ourselves have no control over. With this in mind I ask that Honeywell at the very least provide basic local control and data logging capabilities with the OPTION of placing the system on the cloud.
Ignoring all of this, Honeywell is a name I trust and I am confident my concerns and those of others will be addressed when the final API is released. I look forward to seeing what this API can do! Simply based the current capabilities and expansion possibilities of the Prestige I will likely add additional HVAC equipment such as a dehumidifier (I have a fish room), whole house HEPA, and UV sterilization.
A note to UDI, I would gladly purchase a module based on this API.
