===== General description =====

Wireless on wall power meter PM1-WN-W is a on wall mounted control unit. It can switch on/off an external power-relay and measure active power and energy consumption. 

This device has to be directly and continuously main powered. For network purposes, it is a Router (Repeater) i.e. it has function of maintaining radio traffic from and to other similar devices and it can also act as a parent device for battery-powered sensors of the same family.
