HA control of your Air Con unit

["Ian Bird" <I.Bird@xxxxxxx>]

Having read the previous post about automating the Homebase A/C units I was
just wondering..

I have HomeVision but am currently using most of the relay output ports for
my watering valves. I know Port C can be configured for output but can only
drive ttl, cmos, leds or similar. I don't see any reason why this could not
drive a transistor and that in turn either simulate the switch or a relay
to
simulate the switch (depending on the requirements). That would give HV
control over the unit with manual override available (but no feedback).

This is something I might look into soon(ish) as it would be dead useful.
The lack of feedback would not bother me particularly as I could always
reset the unit using an appliance module e.g. prior to turning it on.

If you don't have HV then back t  the drawing board. If this and another
interface could be designed into the same unit then let me know and we'll
think about it.

Phil - have you taken off the panel or whatever yet (defeated the anti
tamper screws)?

Ian
