Me too a newbe too; buy yes the CR234 is a coupler/repeator. Coupler/Repeators are used to increase HA systems reliablity. I am using all 2-way devices so I am trying to build a nice stable system. Some other options are the Lightolier Firewall and Smarthome's plug-in coupler if you have 220 service in your home. These forums have a lot of infomation in them. This thread
The Right Stuff may give you better explaintions.
Here is a link to the c/r I will buy
CR234 But use this for info only, it has a PDF manual you can look at. For buying anything try
automatedoutlet I can't seem to find lower prices than Martin's.
Martin:
Thanks, I should be ordering that c/r in a couple of days. Of course I am gonna try to enter the "secert code" and see if I still get free shipping.
