Skip it if
- You want humidity sensing: the control-feature list does not include it.
- Your heating and cooling equipment is unusual: ENERGY STAR does not list system compatibility (n/c), so use the maker’s compatibility checker.
How it ranks in the ENERGY STAR list
- network standby power (W): 0.34 — rank 26 of 115 certified smart thermostat models (lower is better).
- static temperature accuracy (smaller deviation): 0.81 — rank 77 of 115 certified smart thermostat models (lower is better).
Ranks compare this model with every smart thermostat in the ENERGY STAR dataset (2026-11-06), not with products on sale today.
Reading these specs
- Static temperature accuracy
- The accuracy figure ENERGY STAR lists for the thermostat’s temperature reading. A smaller number is a smaller listed deviation.
- Network standby
- Average power in watts while the thermostat is in network standby.
- Control features
- The heating and cooling control features the maker reported to ENERGY STAR, such as geofencing, occupancy sensing or humidity sensing.
- Connectivity
- Communication methods the listing reports. HVAC system compatibility is not part of the dataset (n/c).
Noise level is not part of the ENERGY STAR dataset, so it shows as n/c. Check the maker’s own specification sheet for decibels.
