The State of IP (Web-Based) Enabled Thermostats.

Lux Products' Model TX900TS Touch Screen Thermostat

[This post was updated on 4/10/12. It now includes revised and expanded information. Please let me know if anything is missing!]

I’ve been looking into IP-based thermostats, that is, thermostats which can be managed remotely via the web. I’ve collected a number of vendors below. The idea is coming into its own and a number of companies have picked up on it and it is a great idea – as it could significantly lower electrical costs for homes and businesses. Before I move on to the actual reviews here are a few questions I have I’d love to hear your thoughts on:

  • Do you know of any other companies that manufacture and/or sell IP enabled thermostats?
  • Do you know of any companies that offer discounts to non-profits?
  • Do you know of any companies which support LAN-based thermostat management but not internet-based? I’d like to add them to the list…as they can be managed remotely via programs such as LogMeIn.

ecobee

  • Are sold through a local contractor, not directly from the manufacturer.
  • On eBay the units appear to be selling for $300-$500.
  • The website is very nice and the device appears very nice, but you are going to pay a premium.
  • They have a new device with an apparently lower price this month (April 2012).

Radio Thermostat

  • Sold directly from the manufacturer.
  • Price ranges from $140 to $250.
  • Also rebranded by Filtrete and sold through Home Depot at a cheaper price ($100).
  • Requires either a “C” or “common” wire or an external transformer for power.
  • Site and thermostat both look aesthetically pleasing.
  • Sometimes distributed as Homewerks (e.g. on Amazon).

Proliphix

  • Has mobile websites created to support major mobile phone providers.

  • Pricing is around $220/ea. for thermostats.

Net/X

  • Cost for thermostats themselves is $300+.

  • Cost is $200 per unit for the basic level.
  • Includes wireless built in.

Do you have a preference for any of the mentioned t-stats? Where are the reviews?

Been doing my own searching into available products and came across your article. There is one more to add to your list: x300 by ControlByWeb found here: http://www.controlbyweb.com/x300/

A couple of features I like about it are:
1. Does not force you to use the manufacturer’s web portal to access the device (e.g. BayControls, ecobee, proliphix, schlage)
2. Can be wired in parallel with existing thermostats, so you can have both local and remote control

I cannot believe that none of these have a simple home LAN interface. Am I just missing something?

I really don’t believe in 3rd party websites, nor their monitoring and intrusion into my private home network.

If anyone knows of a LAN based solution, please post! I’ve now returned 2 because they said you could control them with your “home network” which is very misleading.

Dave,

You may be interested in knowing that Home Depot is now carrying a line of network enabled (wireless) thermostats. I saw them last week when walking through the store. Home Depot’s website has them listed as well. Depending on the features needed (in relations to the HVAC unit itself)ranges in price from $100 to $200 or so. It is not clear if the wireless module is included or required option (addl $80). The brand is called Lockstate.

The slickest thermostat seems to now be the NEST.

Very helpful. I did this research about 2 years ago and there weren’t nearly as many choices. Out of all these, I like the Nest the best, although I don’t know yet if I can make it work with my system. When I designed the wiring I *assumed* IP thermostats would be easy, and just ran CAT6 cable to each thermostat location. But they are all designed for standard HVAC wiring, even the most modern ones like the Nest. I think their market is retrofitting. Also, if you have multi-zones HVAC like I do, you need to spend some time looking at the zone controllers which are even more archaic than the thermostats. Still, thanks — I’m ready to do something now and you saved me a ton of time.

Great list. I didn’t like the idea of the Nest or other “connected” thermostats, but I’m warming up to them. One of the better selling points was the ability to control the unit from an app. I could see that coming in handy, if I wanted to have the house cool or hot when I arrived.
