ya i wanted a set of pool controls on the patio (light/pump/etc)...
if i were you (and i'm in the same boat) i might holdoff and see if with the new serial interface firmware and programming tool if elk will accept scene commands (as Vizia defines them - on a per controller/button basis) . Cause if you could assign no devices to a scene/zone button on the 4-button controllers, activate it, and drive that as a lighting change event in the rules, you'd still get what you want (and still have two way comm) - that is in fact what i am hoping to do in conjuction with the relay approach:
button
1: pool pump
2: pool heater
3: pool light
4: back landscpage lights
