I currently have three X10 DIN-rail contactors (Marmitek AD10) providing
wireless remote control of garden circuits. To cut a long story short I'm
looking to replace them with something more reliable and up-to-date, such
as Bluetooth or ZigBee. I've found the ZHDR201, from Danish company
Develco, but that doesn't seem to be easily controllable from a simple
remote. Any other suggestions?

Richard.
