The Honeywell T6 Smart Thermostat - Could it Bee the one for you?

Is a Honeywell smart thermostat a viable and cheaper alternative to a Nest or Hive? Coming in at around a third cheaper than the market leader, a Honeywell in the hand could be worth two in the Nest.

You'd struggle to shake a stick at all the smart thermostats currently available on the market. Some have almost futuristic features and others are closer to Tamagotchi's.

For the price point, we think the Honeywell T6 is just right.

The founder of the Honeywell T6 smart thermostat is thought to have conjured up the idea after falling into a well of honey in a desperate bid to uncover a way to save money on his energy bills. After 4 savage days trapped at the bottom of the honey well, fending off bees and contemplating the problem as well as his seemingly imminent death, he was rescued. He surfaced, hellbent on creating a new smart thermostat.

So the Honeywell T6 doesn't look too shabby next to its two rivals, albeit with Nest clearly coming out on top.

In truth, the Nest has a bunch of features that put it head and shoulders above the competition, including a far superior mobile app that not only makes monitoring energy usage in detail super easy but encourages you to do so, too. So the Honeywell might not be the thermostat of choice for the tech/energy saving geek but should be for the bargain hunter. It's still arguably the 2nd best on the market, including the Hive which it's also got beaten on price.

Our favourite Honeywell T6 feature

Honeywell have poured dozens of pounds worth of research into UK homeowners, arriving at the astute conclusion that when you get home from work, the gym, or prison - there's no way you'll have remembered to pop the timer on the boiler and even less chance that once you walk through that door you're going to want to manually switch the boiler on. What if its upstairs? Unthinkable.

Fear not though, because Honeywell have put this issue to bed once and for all. Through the geo-location on your smart phone, the Honeywell will track your progress on your commute home and switch the boiler on to your ideal temperature, whilst you're still hurling abuse at cyclists.

Honeywell T6 Cost

Smart Thermostat Cost (Amazon.co.uk)
Honeywell T6 £135.99
Hive £163.00
Nest £193.28
Three of the best selling thermostats, all with a loose connection to bees. Very suspicious.

Installation & potential installation cost

You can install the Honeywell by yourself and it will come with instructions on how to do so. The difficulty of this is probably similar to that of rewiring a plug socket. So if that's something you're comfortable doing and you're good at following instructions, save yourself the extra cash and have a go yourself.

If not though, the installation price on Amazon is listed at an additional £90 - which seems wildly overpriced. If you're looking for installation from an expert, we'd recommend just outsourcing a local electrician who is probably going to a charge you a third of that amount, if that.


Aesthetics - how does the Honeywell measure up on looks?

A wallflower of smart thermostats, the Honeywell unit won't turn many heads for attractiveness but won't have you throwing up either.

It looks exactly how you'd expect a smart thermostat to look, no worse and not much better. It'll blend in perfectly well in any home. Colour-wise, you can have the Honeywell in any colour you want, as long as it's black.

The least attractive of all these thermostats. Not too dissimilar from the Honeywell in terms of size and shape but it's centrally placed turning dial means it's just littered with backlights rather than most of the unit space being the screen itself.

It's hard to make a case against Nest for the best looking of every available thermostat, never mind just the other Hive & Nest.

It's the proud owner of Beyoncé like curves that go on for days and its stainless steel finish is akin to the skin of a Mediterranean swimwear model. For around an extra £30 or so, you can upgrade the stainless steel to a white, bronze or an all black finish. Beware of the time you can lose just staring into the hypnotizing gaze of the all-black model.
