The Honeywell can be controlled over Wi-Fi using the free Honeywell Total Connect Comfort iPhone/iPad app, which according to reviews in iTunes works quite well to control thermostat.

According to those who have installed this thermostat it does require a “C” wire to run this unit. Anyone own one of these Honeywell Wi-Fi thermostats? Let us know how it goes if you pick one up!

    No I have the Nest which works extremely well. Would be nice to have a similar unit that controls lights i.e. lampshades etc.

    why are most thermostats out there look so ugly? Nest excluded 🙂

    Nothing beats the NEST Thermostat

    Dammit, this thermostat was unavailable in Canada as of just a month or two back, and now that I went another route for a web-controlled thermostat (the Ontario Peaksaver program), suddenly it pops up on this side of the border.

  • Hate it when that happens, eh!

  • The lack of design means it’s a lot cheaper

  • Dk

    I don’t like the “learning” nature of the NEST – our house is so unpredictable (2 teens and 2 busy adults) that it would never be able to truly learn our habits – half the time the house would be heated/cooled when we’re not here, and there’d be times when we ARE unexpectedly here and it would have to play catch up when it realizes we are home unexpectedly.

  • Mark Morissette

    I may get the Peaksaver thermostat removed now and go this route. The Peaksaver was free and it DID allow me to get web controllability, but it’s very limited (only a 1-way interface, so commands can be sent to the thermostat but you receive no data/feedback in return), and the web interface is clunky at best – no mobile app, either.

    You don’t need to use the learn mode at all.
    You can set the programming for the most predictable routine, then turn on “Auto-Away”. Nest would turn down the heat/AC when it detects that you are away.
    And you can also control it from you iPhone, and turn up the heat/AC BEFORE you return “unexpectedly”.

    What the heck is a “C” wire?

  • Fox

    Some digital thermostats are able to power themselves off of batteries (blah) or to utilize the wires which run the heating/cooling circuits, but most modern digital thermostats need a dedicated power return common or ‘C’ wire (along with the standard 24V wire) to power up. Think of it like the neutral wire in 120V circuits.
