2026 verdict
Same wall footprint, same radar and same Matter: the Honeywell Home X8S Smart Thermostat is the more complete smart thermostat of the pair, with a 5 inch screen, a speaker and a wireless room sensor in the box.
The Honeywell Home X7S Smart Thermostat matches it on dual-band Wi-Fi, occupancy sensing, Matter and platform support, including Apple Home, Alexa, Google Home, SmartThings and Home Assistant, on a 4.3 inch color screen. It is the lower priced of the two, which is its case, and it adds a temperature alert the X8S does not confirm. The X8S also streams a compatible doorbell to its screen. Choose the Honeywell Home X8S Smart Thermostat for a multi-room home that wants the extras, and the Honeywell Home X7S Smart Thermostat for the same core smarts at a lower price.

What the differences mean
Screen size
The Honeywell Home X8S Smart Thermostat has a 5 inch touchscreen and the Honeywell Home X7S Smart Thermostat a 4.3 inch one. Both are color and both wake as you approach, but the larger panel is easier to read from across a hallway.
Speaker
Only the X8S has a speaker, which is what supports its doorbell intercom. The X7S has none, so it is a thermostat and nothing more at the wall.
Room sensor in the box
The X8S ships with a wireless room sensor, ready to prioritise a bedroom or office. The X7S supports external sensors too but lists none included, so they are an extra purchase.
Doorbell viewing
The X8S can show live video from a compatible First Alert or Ring doorbell and talk back through its speaker. The X7S does not offer this, and either way the doorbell itself is sold separately.
What is identical
Dimensions, weight, dual-band Wi-Fi, occupancy and humidity sensing, Matter and the platform list are the same on both. Both need a C wire, and both carry a 2 year warranty.
Which one to buy if
- you want a room sensor from day one
The Honeywell Home X8S Smart Thermostat includes one, while the X7S lists no sensor in the box.
- you want to see and talk to the front door from the hallway
With a compatible First Alert or Ring doorbell, its screen and speaker act as an intercom.
- you want radar presence sensing and Matter but not the extras
The Honeywell Home X7S Smart Thermostat has the same occupancy sensing, Matter and platform list for less.
- a screen you read from a distance is not important
The 4.3 inch color touchscreen of the X7S does the same job as the X8S's 5 inch panel at arm's length.
