Demand responseHoneywell Home connected thermostat family is enabled to respond to Demand Response (DR) events that utilities call to mitigate certain risks to the grid. These programs ultimately save consumers money while preventing adverse effects on their service. Honeywell Home thermostats are utilized by a variety of optimization/DR firms that access our thermostats through APIs. Set points can be continuously optimized for a number of factors including real time weather and a homes thermodynamic properties, resulting in additional energy savings. Similarly, our thermostats can be controlled by multiple Demand Response Management Systems (DRMS) systems shedding load at peak periods. Features include pre-cooling and various shed strategies (cycling, temperature off-set, etc.). Our UI and apps allow for consumers to be alerted of events and offer the ability to opt out should the need occur. Feedback on an events opt-outs, overrides and load shed performance are available through API to the Load Managing Entity.

Skip it if

  • You want geofencing: the control-feature list does not include it.
  • 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): 1.65 — rank 93 of 115 certified smart thermostat models (lower is better).
  • static temperature accuracy (smaller deviation): 0.35 — rank 23 of 115 certified smart thermostat models (lower is better).

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.
