    Proliphix's Internet-enabled thermostat
    During those odd weather patterns, I've often thought it would be nice to adjust the temperature settings at home, or perhaps increase air circulation, etc. So I bought an OmniPro II home controller system [smarthome.com], which does this--and more (lights, security, etc)--remotely. So, the Proliphix isn't the first of its kind... but it's still a "cool" idea ;)

My goal for the AC was simply to turn it hard ON for half hour before I got home, regardless of temperature.

    I'd say the majority of people with DSL/Cable in the US have user agreements stating no servers. Certainly this is a simple one, but a server nevertheless. Also, I venture a guess that most people have no clue how to set up their firewall to accept incoming sessions.

    As more and more home appliances become Internet accessible, it will be interesting to see how things like this take hold.

    • most DSL/Cable providers don't care if you do host a server, they just don't want you calling tech support because your web server isn't set up right or bitching that you "very important" server is offline due to an outage

      These stupid AUPs are loads of bull. Every TCP-based application is a "server". What makes apache or this thermometer more of a "server" than, say, a usenet client or outbound ssh session?

      This proliferation of "server" to mean "application we don't like" irritates me as much as "router" to mean "NAT box".

  • Hi, I work for a company that does (technical) Facility Management for a lot of huge companies. We have our own system that allows us to attach any kind of analog signal (incl thermostat) to an internet enabled network. Or proprietary system is about 7 years old, but we also use of the shelf systems from:
    - Siemens (http://www.sgm.siemens.de/)
    - ABB (http://www.abb.de)
    and many big names more

    but the newest thing, I personaly like is this device from ICONAG: http://www.iconag.com/

    This is from their "Multi-tenant [proliphix.com]" page:
    To further save unnecessary expense, facility managers can remotely lockout each tenant by disabling the thermostat buttons from tenant interaction to safeguard against inefficient temperature overrides.
    • I'd prefer a "soft" lockout, with sauna-and-artic like temperatures restricted.

      Or could it have enough smarts to do something like :
      Calculate the average energy use in the building in a one week window.
      Set each tenants available thermostat range depending on where they fall with regards to the rest of the tenants -

      If they are above the average, restrict their available range of deviation from ambient outside, depending upon how much above the average they are.

      Likewise, expand their available range if the

    Those guys had a link on their website where you could adjust their thermostat and turn their lights on and off in real time via the web way back in the year 2000.

  • It looks like it controls the HVAC using 24V AC switching. Is that still used in the USA?

    Over here (Netherlands) any modern heating system uses a digital serial link between the equipment and the thermostat. The thermostat not only switches the heater on and off, but can also set the level (modulation), read back and display status information, set parameters like hot water operation mode etc.

    As it does not use straight on/off switching, such a system operates much more smoothly. Rather than cycling th

  • See also Residential Controls' RS232 serial thermostat [hometech.com].

    These guys put the control box down by the furnace itself, so instead of having to run wire to the display, you only have to run wire from your PC to the furnace. They fully document the text-based protocol too, so its easy to program for.

    I have one of these and it works fine. Also, no web server means fewer security worries.

  • Is this a real product? I can't find a price or anyone purporting to sell it. The "installer manual" on their web page is nothing but a bunch of marketing drivel, the supposed web interface looks like something done in Corel Draw, and if you click on their "Press" link, its EMPTY.

    Also, there is no mention of an SNMP interface. I can see why someone might skip telnet, but why on God's green earth would someone build a web-enabled thermostat and not include SNMP? Can I get a "duh"?

    Everything which can be controlled locally should be controllable centrally/remotely, so they should all have IP addresses.

    Everything:

    Car breaks down on a road trip, it'll be a week before you're home again. Stop wasting energy: "Thermostat, decrease temperature 15 degrees"

    Ensure that your kids ate dinner as instructed while you work late: "Microwave, when were you last used?"

    The refrigerator should monitor everything that goes in/out (RFID or whatever) and can alert you when you're out. Wouldn't it be nice to be able to check the fridge from work so you know to pick up some orange juice on the way home?

    Everything.

    BUT! (there's always a but!)

    I'm not saying they should all have *PUBLIC* IP addresses. One device should, one fairly secure only-answers-to-the-right-port-knock-sequence device, which interfaces with all the other devices. There should be a way for the devices of your home to communicate with you (and you with them) in order to improve the day to day quality of life, but that communication needs to be secure. In order to facilitate this security, a firewalled "doorman" device would authenticate you before allowing you to see how many eggs are in the fridge.
