Denkovi USB 8 relay board and an 8 relay Hobby-board are on their way today (21 Aug 15).

Photo proof :)
I could even add control of each relay from a your phone (app)

This is brilliant, the app control even brings a bigger dimension into the mix, all in 1 afternoon....superb.

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.

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.

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 “Relay Control”) to the off position. If desired, the relay can be enabled when using the input so that the relay will be automatically energized when the input goes high, without using the 1-Wire controls.

Mick may know for sure.

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
