    This is a really impressive thread - lots here that I want to do and I was looking at plugging a few DS18B20's into a custom Arduino based box in our plant room to measure boiler/solar/store/fresh-water temperatures. Having read this, I've ordered an OWServer box to play with.

    How have you wired these up with the OWServer box? Do you use some sort of junction box or have you created your own?

    I use the EDS OWServer for my temperature monitoring.
    What do you use to get the data from the OWServer box into HomeSeer?

    Many thanks again for the really useful information.

      Each OWServer has 3 RJ11 connectors. I built some RJ11 pigtails to go to screw terminal barrier strips under the server or RJ11 connectors on the ends of CAT6 runs. While there are only 3 wires required, I use a pair for power and a pair for data with common grounds to keep noise to a minimum.

      I use Ultra Jones' Ultra1Wire3 plug-in for the servers.

Your best results will be to schedule high usage devices like water heater, hot tub, etc. Those devices can be turned off during the higher cost periods. The clothes dryer is a little more problematic because all you can do is suggest that loads be run after 9. If you try to control it, you may be in for some domestic disturbance
        Do you happen to know a dryer model with low energy usage? or tips on figuring it out. Its not easy finding info like that.

            I am working on going 100% solar.

              You can use Al's suggestion or the EnergyStar ratings on dryers. The problem with (electric) dryers is that they all have a 4-5 KW heating element and basically heat air and tumble the clothes until they are dry. Their energy usage is fairly similar from one model to the next. Our new LG has an energy saver mode that cycles the heating element off and on, using a longer total cycle time. It is supposed to cut about 10% from the total energy usage. After a month of usage, it uses about 95% of the energy the 20 year old Maytag used. The savings are nominal - at $0.12 per KWH an average load consumes just over 3 KWH or about $0.36, making our savings a whopping $0.02 per load.

              A gas dryer costs less than an electric.

                I know this thread is WAY old, but I was curious what weatherproof box you used for the GreenEye?

                Thanks,
