Features
:
Off
r1
On
R2
Turn R1 in 2Min
for
1hour
Flash R1
(interval)
Group Relays
together
like 1,2,3 so they can be
toggled.
Eg When issued with
the
command “turn On R3” and then “turn On R2” - R3 would turn off before R2
Came on
All this can be
software controlled from the plugin.
All I would need
is
the simple on/off instructions to send to the serial
port.
What you think ?

Sounds
good to me. Can you start putting together a wish list of features. I will
be
using a PIC micro controller and a serial interface at up to 19200. I might
even make the baud rate selectable. Think about things like the commands
you
want to send e.g. R1 on, R1 off etc. You might want an acknowledgement as
well. Lots of fun.
I am
trying to keep it simple initially so commands like R1 on for 1 hour then
xyz
will not be in the first release.

I would love to be a beta

I have homeseer and volunteer to write

I
have ordered the PCB's so assuming no mistakes on my part boards will be
available from about the 9th September. I am away on hols for a little
before that ;-))
Details and
pictures are on my site at www.mollyology.com then projects and
relay board. At the moment it is aimed at HV and Comfort users but I will
be putting together a small simple serial interface for it. This latter
bit will make it very similar to the unit you have. You can be my beta
tester if you like ;-))
The
relay board is opto isolated as well so none of that nasty AC stuff going
anywhere near your precious PC.

When I was
designing my relay board I initially used reed relays which had some
problems with things like capacitive loads, AC etc. The relays on the
SOM1 look very similar so you may be experiencing similar problems.
Check the relays are actually switching off somehow with the speakers
connected and showing the problems. Alternatively use one of my boards
<grin> which are rated up to 120v AC and everything else you can
think of.

Loudspeakers use an AC signal, not DC.
There is no concept of a
common ground, so you can't switch it
that way.
