Brian,
I have ordered the relay unit and usb interface, I’ve no problem sending them to you to use for your testing, I will also include return shipping, would this be ok, if so pm me your address and I’ll send it when I get it.
Ian
Great, as soon as I get it, I’ll test it and send it on.
Cheers
Ian
Denkovi USB 8 relay board and an 8 relay Hobby-board are on their way today (21 Aug 15).
Cheers
Ian
thanks !
Hi
It arrived today
and I got it working , all in 1 afternoon 
This is brilliant, the app control even brings a bigger dimension into the mix, all in 1 afternoon…superb.
Ian
the latest update of WD has a new version of HB1 wirereader
with support for the 8 channel 1 wire relay
where you can set which channel is turned on or off via a schedule or triggers (temperature and windspeed…I could add rain too)
I could add iphone/android app control over your local LAN (WIFI) easy enough (e.g like how the WDliveapp works)
but to do control over the internet to your phone is harder…will need to think about the best way to do that
Hi Brian,
Your addition of the 8 channel relay open so many possibilities for home automation or links into other projects based around external conditions, on my wish list would be:
Rain detected/Rain stopped
Day/Night -
Lightning detected - maybe linked to Thunderstorm limit with so many strikes per second as recorded on WD, so relay operates irrespective of type of system used to detect the lightning,
A future enhancement could be adding AND - OR to the triggers/relays, so for example if rain was detected and lightning detected a relay would trigger giving a sort of confirmed result.
The use of a remote means of operating a relay would add a great deal of value to me.
As an aside - do the inputs on the 8 channel relay board do anything?
Thanks for all your hard work on this.
Ian
my understanding is that you have 8 inputs and 8 outputs
I am opening the outputs (LED light glows)
and I would presume then that then closes the circuit (from the input)
Ah OK, when I had a play with the board nothing much happened so I assumed it needed to have some level of processing via a working connection to a PC.
i might be mistaken

trying to work it out…maybe Niko can help
The saying always read the manual is so true here!!.
Its all in there
As I read it, if you leave the the “Relay Control” switch for a channel “on”, and you apply an appropriate voltage (or link to the +5) on the corresponding input, then the relay for that channel will switch. But the manual isn’t very clear, and I’ve no idea how the software knows if a channel is being used for an input or an output :dontknow:
[quote]The 8-Channel I/O supports eight channels of input or output. By default all eight output relays are enabled. If a channel is used for input the output relay can be disabled by sliding the appropriately numbered relay control DIP switch (marked
I can get the relay LED to light up and you can hear a click
so the relay (output) is being energised
but using my Digital voltmeter and set to make a sound when there is a circuit, I can not find any circuit! (tried all pin combinations)
That’s odd, have you tried putting a piece of wire in the relay terminals and tightening them down, and then trying the meter on continuity, maybe their is a coating on the pcb stopping a good connection.
I am touching on the top of the screw
but I will try in the actual terminal where you put the wire
thats works
whew
for C to NO (common to normally open on the output relay)
Great, I’ve been caught out with touching the screw and no connection before.
