Re: HA without fallback-CBUS

Hi  Rob

lights on"
> button

One evening while playing with xPL Determinators i programmed an all lights
on Determinator...
I was outside in my computer room and the wife was inside and wondered why
the alarm keypad was beeping....I got up to go inside and set the alarm
went
off ;-)) ...i had forgotten that one of the relay outputs on the cbus
turned
on the alarm ..needless to say that Determinator is disabled...;-)

One command i would like in cbus that the upb kit has is a blink command
for
when the alarm goes off you can flash lites without sending contineous on /
off commands....
