Region and Property data is read directly from ecobee and cannot be changed. The System data is not directly available from ecobee, so it is guessed based on other values; it can be changed.

Data

In one way or another, all values are derived from the data provided from the ecobee API. Because much of this data is inconsistent, unreliable, or incomplete, some liberties are taken to normalize it.

System

There is no "system type" value in the ecobee API, so these values are determined by looking at a collection of related values.

Heat

Geothermal, compressor, and boiler heat systems are relatively straightforward to detect. Outside of that, gas heat is assumed if your latitude is greater than 30°, otherwise electric heat is assumed.

Auxiliary Heat

For gas, boiler, oil, and electric, it is assumed that there is no auxiliary heat. Compressors are assumed to have electric aux heat in warmer climates, and gas aux heat in cooler climates.

Cool

Cooling is the most straightforward of these and should have a high degree of accuracy between geothermal and compressor.

Region

Your region is determined from the address you have provided to ecobee. Every address is run through the Address Validation service to ensure accuracy and consistency.

Property

These values are mostly lifted directly from your ecobee. The structure type (detached, apartment, etc) are cleaned up as there is some bad data, but in general what you set up on your thermostat is what appears here.
