Smart plug simplicity or whole-home heating control: which wins?
These two products solve very different problems, so the right choice depends on what you actually want to automate. The TP-Link Tapo P115 is a low-cost smart plug with energy monitoring, ideal for controlling a single appliance and measuring its consumption. The Honeywell Home T6R-HW is a wireless smart thermostat with hot water control, aimed at improving heating efficiency across your home. If you’re trying to cut bills in the UK, this is really a choice between saving a few pounds on plug-in devices or taking control of one of the biggest energy costs in the house.

TP-Link Tapo P115 – Mini Wi-Fi Smart Plug with Energy Monitoring, Schedule On/Off, Energy Saving, Compatible with Alexa and Google Home, White

Honeywell Home T6R-HW Wireless Smart Thermostat with Hot Water Control — WiFi App-Enabled to and Improve Efficiency — Compatible with HomeKit, Google Home, Alexa and IFTTT
Our Recommendation
The TP-Link Tapo P115 is the better buy for most people because it is far cheaper, better rated, and immediately useful for energy monitoring and smart scheduling. At £43.99, it costs £69.95 less than the Honeywell, yet still delivers strong app control and voice assistant support. Its 4.7/5 rating from over 5,000 reviews is also a strong signal of reliability and satisfaction. Unless you specifically need thermostat and hot water control, the Tapo offers the best overall value.
Detailed Comparison
Display
There is no meaningful display on the TP-Link Tapo P115 itself, because it is a plug rather than a thermostat or screen-based controller. Its value comes through the app, where you can view energy usage and set schedules. The Honeywell Home T6R-HW has a proper thermostat interface and is designed to give you direct control over heating and hot water, which is far more important for day-to-day home energy management. Winner: Product B, because it provides a dedicated control interface for a much more significant household system.
Performance
The Tapo P115 performs exactly as a smart plug should: it switches appliances on and off reliably, supports schedules, and tracks energy use. For devices like lamps, dehumidifiers, fans, or a kettle setup, it is quick, simple, and effective. The T6R-HW is in a different class of product, controlling central heating and hot water with app access, smart scheduling, and compatibility with Alexa, Google Home, HomeKit, and IFTTT. In the UK, where gas heating often dominates winter bills, the thermostat has a much bigger potential impact on efficiency than a plug ever can. Winner: Product B, because it manages a higher-value energy system and can influence a larger share of household spending.
Build quality and design
The Tapo P115 is a compact mini smart plug in white, with a straightforward design that should fit neatly behind furniture and not block adjacent sockets as badly as larger plugs. It is simple, unobtrusive, and easy to install. The Honeywell T6R-HW is more substantial, as you’d expect from a thermostat system, and the wireless design makes it more flexible for home placement. Honeywell has the stronger reputation for heating controls, and the product feels purpose-built rather than merely convenient. Winner: Product B, for a more robust and specialised design, though Product A is the neater device physically.
Battery life
Battery life is not a meaningful metric for the Tapo P115 because it is mains-powered. The Honeywell T6R-HW wireless thermostat does have a battery-powered component, but the key point is that it is designed for long-term home use rather than frequent charging. In practical terms, neither product is about battery endurance in the portable sense. Winner: tie, because battery life is not a core deciding factor here and the products are powered differently.
Price and value for money
This is where the Tapo P115 dominates. At £43.99, it is £69.95 cheaper than the Honeywell T6R-HW, and it has a much higher rating of 4.7/5 from 5,043 reviews versus 4.4/5 from 2,322 reviews. For a low-cost smart home upgrade, it offers strong value: you get energy monitoring, scheduling, and voice assistant support without a big upfront commitment. The Honeywell costs £113.94, which is reasonable for a heating controller, but it only makes sense if you actually need thermostat and hot water control. Winner: Product A, by a wide margin on affordability and review-backed value.
Game library/features
Neither product has a game library, so the meaningful comparison here is feature depth. The Tapo P115’s features are focused and practical: energy monitoring, schedule on/off, energy saving, and compatibility with Alexa and Google Home. The Honeywell T6R-HW offers broader home-energy control through WiFi app access, hot water control, and compatibility with HomeKit, Google Home, Alexa, and IFTTT. If you want a single device that can influence heating behaviour and potentially reduce gas usage, Honeywell’s feature set is more powerful. Winner: Product B, because its feature set is more impactful and more relevant to whole-home efficiency.
Overall user experience
The Tapo P115 is the easiest product to recommend for most people who want a simple, low-risk smart home upgrade. It is cheap, highly rated, quick to set up, and useful straight away for monitoring the electricity used by plug-in appliances. The Honeywell T6R-HW is better for homeowners who want to optimise heating and hot water, especially in a UK property where winter heating costs can dwarf the savings from a smart plug. If you are renting, testing smart home tech, or only need appliance control, the Tapo is the better experience. If you own your home and want genuine heating efficiency gains, the Honeywell is the more serious solution. Overall summary: Product A wins on price, simplicity, and review confidence; Product B wins on system-level energy control and long-term home efficiency.
Final verdict
If you want the best value and the safest buy, choose the TP-Link Tapo P115. If you want the product with the greatest potential to reduce a major household bill, choose the Honeywell Home T6R-HW. For most shoppers comparing these two directly, the answer is that Product A is the better everyday purchase, while Product B is the better upgrade for a home heating system.
Buy the TP-Link Tapo P115 if...
Buy Product A if you want an affordable first step into smart home energy saving, especially for lamps, heaters, fans, dehumidifiers, or other plug-in appliances. It is also the better choice if you want to monitor how much electricity a single device uses without spending over £100. For renters or anyone not ready to touch the heating system, it is the simpler and safer option.
Buy the Honeywell Home T6R-HW if...
Buy Product B if your goal is to control central heating and hot water, not just a plug-in appliance. It makes more sense for homeowners who want to target a bigger chunk of their energy bill and improve comfort with smarter scheduling. If you use HomeKit or want a more complete heating ecosystem, the Honeywell is the more capable product.
