Score: 78/100Rankings
The Honeywell Home RTH9600WF is an ENERGY STAR-certified smart thermostat featuring a vibrant color touchscreen and extensive smart-home integration. Its requirement for a dedicated C-wire and incompatibility with certain heating systems limit installation flexibility. Ideal for homeowners with compatible 24 VAC systems seeking advanced display and remote control.
Mysa's Smart Thermostat V2 is a line-voltage Wi-Fi thermostat designed for electric baseboard and similar heaters, delivering up to 26% energy savings with precise temperature and humidity alerts. Its compatibility is limited to electric heating systems and it lacks battery backup and Bluetooth, restricting broader use cases. Perfect for homeowners upgrading electric heating with smart controls and zoning capabilities.

Professional reviewers consistently commend the Mysa V2 for its ease of installation, substantial energy-saving claims, and extensive smart-home integration, positioning it as the top choice for electric baseboard heating upgrades. The main criticisms focus on wiring requirements and the lack of support for low-voltage heating systems.
Direct consumer reviews are not present in the sourced data, but the product’s multi‑pack offerings and emphasis on family‑friendly app access suggest a positive reception among homeowners seeking whole‑home zoning and remote control.
Professional reviewers such as Consumer Reports evaluate the RTH9600WF on smart-feature performance (Smart IQ), manual operation ease, and automation capabilities, but detailed ratings are behind a subscription wall, leaving only a general acknowledgment of its comprehensive smart-thermostat functionality.
