Some time ago I posted asking for opinions on sprinkler controllers that could be manipulated from a remote location over the Internet, there were many suggestions and I decided that I would purchase the Rain8 product. One of the folks that offered advice on the original post asked if I would reply later with my opinion of the product, this is that post. The Rain8 controllers are small devices that utilize a X-10 signal from a PC, a special cable is purchased that connects to the comm port on the PC and then to the Rain8 controller, sprinkler control valves are then wired directly to the Rain8 device. Attached is a picture of how I installed my system, please excuse the fact that this is a basement installation, I needed to have the PC in the basement verses the garage and I now have the ability to cycle valves with a laptop outside or with my Palm cell phone, I know how you guys hate basement controllers. In addition to the Rain8 controllers you also must purchase software to install on the computer that you will be using to send the X-10 signal to the Rain8 controller. I chose MCSSprinklers although I believe that there are several others as well. I purchased the more expensive Pro version as I was mostly interested in the ability to control the system remotely as I travel a great deal. The MCSSprinkler software is very feature rich and I believe can do everything that you could possibly want to do with a sprinkler controller, I won't waste your time listing all of the features as the list is very long, but with a feature rich program complexity also becomes an issue. I am probably not the most computer/network savvy person in the world, but I do use a computer on a daily basis, I found this software to be fairly challenging and not something that you could load in an evening and be up and running the next day, I believe that there are still options that I have yet to figure out and may never be able to utilize them. I was forced to contact customer service twice concerning issues and both times they responded by the next day, I thought that was pretty good. One of the features that the software offers is the ability to calculate evapotranspiration based on local environmental reports taken automatically from the Internet, it seems like a nice feature but I have yet to fully utilize it. In a nut shell this option offers lots of possibilities but with those possibilities comes a fair amount to complexity, I was able to purchase the entire package for less than $350 and used a old Pentium 3 PC that I had at home and was planning to throw out.
