Honeywell Home T9

The Honeywell Home T9 is a solid option if you're in the market for a smart thermostat. With a score of 85 out of 100, it sits comfortably among the best smart thermostats of 2026. Priced at £199.99, it’s not the cheapest on the block, but it offers some decent features that could justify the cost for many.

One of the standout aspects is the room sensor capability, which allows you to monitor and adjust temperatures in multiple rooms. This is particularly handy for larger homes where heating can be a bit uneven. The touchscreen display is colourful and user-friendly, making it easy to navigate through settings. Plus, it integrates well with smart home systems, which is always a bonus if you're looking to control everything from one app or with voice commands.

However, it’s worth noting that the T9 doesn’t have learning capabilities, which might be a deal-breaker for some folks. Other smart thermostats can learn your schedule and adjust accordingly, but this one relies more on manual input, which can feel a bit old school. If you’re someone who loves tech that adapts to you, the T9 might feel a bit limiting.

In terms of value for money, it’s pretty reasonable for what you get, especially with the added room sensors. Energy-saving features are a nice touch, helping you keep those bills down. But if you’re on a tighter budget or don’t need the room sensors, there are cheaper alternatives out there that do the job just fine.

Overall, the Honeywell Home T9 is a reliable smart thermostat with useful features, but it might not be the best fit for everyone. If you place a high value on multi-room control and smart home integration, it’s worth considering, but if you want something that learns your habits, you may want to look elsewhere.
