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 tester,
I have
homeseer and volunteer to write a plugin if you
like

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.
