2026 verdict
For a household that mixes Alexa, Google and Apple devices, the Honeywell Home T5 Smart Thermostat is the better buy of the two: it supports all three, plus SmartThings and Home Assistant, on a 4.95" touchscreen.
It adds geofenced Auto Home and Away, a 7-day schedule, monthly energy reports and a system health monitor. The Amazon Smart Thermostat is the more basic, Alexa-only thermostat, with a monochrome LED display, no alerts and no touch, but it ships with a C-wire adapter and a trim plate. The Honeywell Home T5 Smart Thermostat needs a C wire or a power adapter of its own. Choose the Honeywell Home T5 Smart Thermostat for platform choice and features, and the Amazon Smart Thermostat for a simple, self-contained Alexa install.

What the differences mean
Smart home platforms
The Honeywell Home T5 Smart Thermostat works with Google Home, Alexa, Apple Home, SmartThings and Home Assistant. The Amazon Smart Thermostat works with Alexa only, so a Google or Apple household has nothing to connect it to.
Display
The Honeywell Home T5 Smart Thermostat has a 4.95" touchscreen LCD that shows time and temperature. The Amazon Smart Thermostat has a monochrome LED display with no touch, and it shows the temperature only.
Scheduling and savings
Both schedule manually and automatically. The Honeywell Home T5 Smart Thermostat adds geofencing, ENERGY STAR certification, monthly energy reports with tips and a system health monitor, none of which the Amazon Smart Thermostat lists.
Alerts
The Honeywell Home T5 Smart Thermostat sends temperature alerts. The Amazon Smart Thermostat has no alerts of any kind.
What is in the box
The Amazon Smart Thermostat includes a C-wire adapter and a trim plate that covers marks from an older thermostat. The Honeywell Home T5 Smart Thermostat includes its UWP mounting system but no cover plate, and needs a C wire or a power adapter.
Which one to buy if
- your home runs on Apple Home or Google Home
The Honeywell Home T5 Smart Thermostat supports both, while the Amazon Smart Thermostat supports neither.
- your walls have no C wire and you don't want to buy an adapter
The Amazon Smart Thermostat includes a C-wire adapter in the box.
- you want the thermostat to switch to Away when everyone leaves
The Honeywell Home T5 Smart Thermostat uses your phone's location for Auto Home and Away.
- you want a touchscreen you can read across the room
The Honeywell Home T5 Smart Thermostat has a 4.95" touchscreen, and the Amazon Smart Thermostat has a small non-touch LED display.

What owners say
Honeywell Home T5 Smart Thermostat owners call it the sensible budget smart thermostat. They single out the flexible schedule and the geofenced Home and Away switching that do the actual saving, the large touchscreen that reads across a room, and an install so quick that people replacing an older Honeywell often just pop the old unit off and the new one on. Their complaints are the lack of remote room sensors and humidity sensing, an app that a minority find unreliable, and a few units that would not work with their system or responded slowly.
