Honeywell evohome smart thermostat system launched

The Honeywell evohome smart thermostat has been launched, offering intuitive smart zone technology.

Available to purchase through the Honeywell Installer Network now, the evohome system uses special sensors for individual rooms to offer greater control.

“In the same way you don’t only have one light switch for your entire house, we believe you shouldn’t control your heating with one single switch”, said Jeremy Peterson, Honeywell EMEA Home Comfort and Energy System division GM. “With the right heating controls in place, you really can make your home your perfect comfort zone by setting different temperatures for different rooms, at different times.”

Evohome allows up to 12 zones to be created in your home by placing individual wireless nodes on your radiator valves.

These modules communicate with the main controller paired with your boiler to let you create zones that can be managed separately.

“We’re done extensive testing proving the energy saving benefits of smart zoning and having an accurate, real-time insight into home heating. With uncertainty surrounding energy bills and wintery conditions across the UK, we believe it can help households make real savings on energy bills.”

The nodes are pretty smart too, as it’ll recognise when a particular zone in the house changes temperature and adjust the heating accordingly. Imagine if you left a window open in a particular room, evohome could turn off the radiator in that zone to make sure you’re not wasting energy.

Evohome also learns how quickly your house can be cooled or warmed throughout the year.

Honeywell claims that upgrading from a basic timer and thermostat controls to the evohome Smart Zoning system could offer 40 per cent saving on your heating.

The Honeywell smart thermostat system can be controlled via Android and iOS apps that can be programmed with particular heating schedules even if you’re not at home. It also features quick actions like “day off”, “economy” and “away” for when you’re going on holiday.

Pricing for Honeywell evohome starts at £249 (without the radiator nodes) and are available now.

Wow, 40% of your heating bill is going to save some serious cash! Looks like a nice piece of kit too, but very similar to the Heat Genius system that was launched last year? That one is the same price and also controls individual radiators, but with the additional option to add motion sensors - then it will learn when you use each room and schedule the radiator to come on automatically. That seems kinda funky!

Nice idea, but I've just been through the evaluation page, and it said it would be £1.6k without installation costs. At 40%, if that were true, it's going to take 4 years just to pay off the purchase cost according to their own site, and I imagine the installation costs would add another year or two to that, and so at a probably more realistic 20% saving, it's going to be more than 10 years to pay for itself. Not that great.

Most homes will have thermostats on their rads anyway that control the heat for that room. What I want is a simple timer clock with wifi so I can turn on the heat from my phone when i am on my way home. This would be a direct replacement for most peoples timer clocks.
Honeywell sell them in the US for about £120 but for some reason they will not sell them in Europe: http://yourhome.honeywell.com/...

Whats your current Gas bill? Mines around 4k for a large detached 4 bedroom house, some with double rads. This will save me money within the year especially as house only has 3 people in it.

I have Honeyell evohome
in use since 4 years.

1 Level (/Floor) with
6 floor heating controllers(valves) and 6 HR80 radiator valves over 3 levels
+boiler relay. Of course in max 8 zones (with new Evo surprisingly only 12).

Evohome (and its newer brother) is good for installing and forgetting but frighteningly proprietary and therefore quickly outdated.

When you are only interested in rudimentary heating, Evohome is sufficient but slightly
overpriced since 3 years.

Of course, if you have one room (nest) and only use it occassionally for sleeping then Nest is really a cheaper alternative.

If you

1. have more than 25 square meters living space,

2. have cyclical&non cyclical varying behavior patterns (like overnight visitors, guests for 3 weeks, party mode),

3. compensate for children not using their rooms for 12 hours in a day (in school season but more during vacation – but only when @ home);

4. have four seasons (in contrast to “energy saving” or “off”), or

5. or would maybe like to see zone graphs of energy usage in the far future,

you'll be very disappointed with this model (or its newer brother).

In retrospect, I would rather suggest buying Homematic (which I also have in use, since 3 years, but for other types of home automation (lightning, security, presence etc.)

It is expandable (no zone limits),
-secure,
-also supports heating features like window open, self-maintenance during summer time, avoids frost, ...
-knows about daylight savings,
-supports open standards (RS485, "+internet/apps
-(+can coexist with other brands) (-ie can be controlled
via php scripts/ electronic/mechanical switches,contacts , (if you ever want to go that far).
-allows simple and complex (via script) customization, to own needs
-you can also control the boiler via actuators (relays
etc.),
and is therefore extremely flexible.

Maybe the only difference is that the setup time with Evohome it is 3 hours (including wall mounting sync'ing etc) and the Homematic is 4 hours. Once you're stuck with Evohome you can't evolve. Adding a 9th/13th zone means buying a full new controller !? I felt very locked-in after 2 years... good product but locked-in. The Evohome had 1 simple update (not mentionable feature) over 4 years. This upgrade could be done only by an accredited Honeywell technician or a rocket scientist. The Homematic had ca. 4/5 updates in the same period, adding several useful features.

If you're
*a DIY average Joe,
*willing to invest a bit of time,
*and prefer to have flexible and adjustable control and evolving needs over the next 10 years
*but not a zigbee evangelist or arduino programming type to start reinventing heating systems from scratch,

then go with Homematic.
