Lux Products' Model TX900TS Touch Screen Therm...

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).

  • Sold directly from the manufacturer.
  • Price ranges from $140 to $250.
