Shipped to me as a replacement for a Solar Analytics KR-63 Device after they turned off the 3G capability of the device. I believe they are a direct plug in replacement for the device. The instructions are with it.
I have never used the device and I would assume it works. However I can offer no guarantees and you are buying this item AS-IS and UNTESTED.
I am not sure if it is still being supported by SA or wattwatchers so it is up to you to do your own research to find out if this product is suitable for you.
As always, these items need to be installed by a licensed electrician.
