 ====== NetHomeServer Nexa Connection ======
-Nexa is a radio based system for remote control of switches and dimmers. It also includes PIR-detectors, magnet switches for windows and other detectors which work as remotes and can control the switches.
+Nexa is a radio based system for remote control of switches and dimmers. Nexa is really just one of the names this system is sold under. The actual devices are made by ArcTec, but branded by resellers in Europe and US. It is also sold under the product names: Chacon, Elro AB600 and Proove. The system also includes PIR-detectors, magnet switches for windows and other detectors which work as remotes and can control the switches.
-Nexa has two addressing systems, one old where devices are explicitly given a house code and device code and one newer "self learning" system where transmitters have unique addresses and the receivers "learn" the code of the sender which is controlling it. NetHomeServer supports both variants, which in reality are two entirely different protocols.
+Nexa has two addressing systems, one old where devices are explicitly given a house code and device code with code wheels and one newer "self learning" system where transmitters have unique addresses and the receivers "learn" the code of the sender which is controlling it. NetHomeServer supports both variants, which in reality are two entirely different protocols.
 The Nexa system have no native computer interface. It does however use the standard 433MHz radio band (in Europe), which makes it possible to use the generic 433MHz receiver and sender of the NetHomeServer to send and receive commands to and from Nexa devices.
