EB-STATE3LT-02Black 3 year limited warranty.

Smart Thermostats

Integrated HomeKit/Siri, Alexa, Google Assistant, and SmartThings connectivity for multi‑platform voice and app control.

✓Included SmartSensor provides room‑specific temperature and occupancy data for improved comfort and energy savings.

✓5‑year warranty on professional installation adds long‑term peace of mind.

Cons

✗Requires a C‑wire or Power Extender Kit; cannot operate on battery power alone, limiting installation in some homes.
✗Smaller 3.5‑inch display with lower resolution compared to premium models may limit detailed view of settings and graphs.
✗Limited Wi‑Fi bandwidth usage (~15‑20 MB/month) could be a concern for users with data‑capped internet plans.
✗No built‑in speaker or microphone, so voice commands rely on external assistants rather than native voice processing.
✗Advanced wiring options like ACC+/- are not supported out‑of‑the‑box, restricting some high‑end HVAC configurations.
