Pros & Cons
- •Best-in-class multi-room temperature averaging — supports up to 20 Honeywell Smart Room Sensors at a 200 ft range, with motion detection that prioritizes whichever room is actually occupied rather than averaging the empty den into the bedroom temperature.
- •PCMag's Best for Remote Room Monitoring 2026 (4.0/5 Excellent) — the sensor algorithm specifically targets the 4,000+ sq ft multi-zone use case that the ecobee Premium's single included SmartSensor struggles to cover at scale.
- •Geofencing auto-Home / auto-Away via the Honeywell Home app — mobile phones cross the geofence boundary and the thermostat switches modes automatically, which scales to multiple household members on different schedules.
- •Multi-stage HVAC and heat-pump compatible — handles the more complex US HVAC setups (multi-stage gas, multi-stage cooling, dual-fuel heat pumps) that simpler thermostats struggle with.
- •Resideo Honeywell Home app is rough — r/homeautomation has multiple 'Unable to connect to Resideo app' threads, and the app is consistently called out as 'the worst app in the field' across community sentiment in spring 2026.
- •No HomeKit support — Apple Home households get nothing native from the T9; the Sensi Touch 2 is the right Apple Home cross-shop with comparable hardware quality and a real HomeKit pairing.
- •C-wire required and Honeywell does not include a power adapter — older US homes built before 2000 will need a separately-purchased Power Extender Kit or third-party adapter, which adds install friction the ecobee Premium and Essential don't have.
- •Stock churn on the T9 SKU as of 2026-05-11 — Amazon listing flagged limited stock; CNET's 2026 update points to the newer Honeywell Home X8S as the successor, which is not yet at our review-volume threshold for this guide.
