Honeywell Home X8S Smart Thermostat vs Sensi Touch 2 smart thermostat

Full Smart Thermostats comparison in 2026

Updated October 2026
Data from Amazon and official Honeywell Home and Sensi sites.
2026 verdict
For a large home that wants the thermostat to be a control centre, the Honeywell Home X8S Smart Thermostat is the more advanced of these two.
It pairs a 5-inch customisable touchscreen with an onboard radar sensor for occupancy, humidity and ventilation control, room prioritisation through an included wireless sensor, Matter and Apple Home support and the option to stream a compatible First Alert or Ring doorbell on the wall. The Sensi Touch 2 smart thermostat costs less and keeps a clean 4.3-inch glass screen, a guided DIY install and support for external sensors, but it skips occupancy sensing, air-quality alerts and the system health monitor, and it works with Google Home, Alexa and SmartThings rather than Apple Home. Choose the Honeywell Home X8S Smart Thermostat for the widest sensor set and the deepest smart-home integration, and the Sensi Touch 2 smart thermostat for a good-looking touchscreen at a lower price.

What the differences mean

Sensors on the device

The Honeywell Home X8S Smart Thermostat has an onboard radar sensor for occupancy and presence detection plus a proximity sensor. The Sensi Touch 2 smart thermostat has neither, so it reacts only to the schedule you set and any external sensors you add.

Display and idle screen

The Honeywell Home X8S Smart Thermostat has a 5-inch touchscreen that can show a five-day forecast, indoor air quality and even live video from a compatible doorbell when idle. The Sensi Touch 2 smart thermostat has a 4.3-inch glass touchscreen that mainly shows the temperature and controls.

Room sensor in the box

The Honeywell Home X8S Smart Thermostat ships with a wireless room sensor and prioritises the room it sits in. The Sensi Touch 2 smart thermostat includes none, though it supports add-on external sensors for multi-room balancing.

Platforms and Matter

The Honeywell Home X8S Smart Thermostat is Matter certified and works with Apple Home, Google Home, Alexa and SmartThings. The Sensi Touch 2 smart thermostat covers Google Home, Alexa, SmartThings and Home Assistant, with no Apple Home and no Matter.

Doorbell viewing and system health

The Honeywell Home X8S Smart Thermostat can stream a compatible First Alert or Ring doorbell and monitors system health. The Sensi Touch 2 smart thermostat offers neither, and some of the air-quality control on the Honeywell also depends on extra HVAC equipment.

What owners say

Sensi Touch 2 smart thermostat owners focus on the install and the look: they describe the app's step-by-step walkthrough as clear enough to self-install without an electrician, and they like the 4.3-inch glass touchscreen next to an older thermostat. Buyers who add external sensors mention balancing temperatures room by room rather than trusting the single reading at the device. Their complaints are that it has no Apple HomeKit support, no occupancy sensing, no air-quality alerts and no system health monitor, and a minority report Wi-Fi dropping after a few months or trouble pairing a remote sensor.
