Proprietary BS

If you’re going to force users to use only your products, you had better offer application and thermostat updates over the air and automatically!! This is by far the worst HVAC platform.

The scheduling app on this is atrocious! Get rid of the 2 and 4 events period!! This is the dumbest idea ever. Just let me make a schedule without events! Have none of your developers ever used any other thermostat!

Example weekends set temp 72 @ 4pm, then 75 @ 11pm, the 72 @ 6:30am and 75 @ 10am.

Then weekdays set temp to 72 @ 4:30pm and 75 @ 9:30pm….

Now for the stats!! Where are they?! I want to see my systems stats and not just the installer only or give me the installer access so I can get them and do what I want with the stats! There is no need for this app to have two different version! The installer has their own device!!

Fan has two options CONT or INTMT

After 2 months of using I still want negative stars!!!!

Missing important features

This homeowner app only shows some of the information available from the symphony system. I would like to see loop and output temperatures, flow rates, and heat of extraction. These features are turned on in the contractor version. Please turn the important features on in the homeowner version. I want read access to all of the information. The lack of information makes this application useless.

Also it would be nice to be able to set a cost per KWH. It would also be nice to be able to program the wattage of the backup heat.
