I finally got around to setting up my diy kit, with my main boards on the way soon, and one of the things I am most excited about is the relay modules and the other things that can be done with them. The ones on my list are my garage door opener and a sprinkler system (to be determined model/brand).
First and foremost, what is everyone doing with theirs? Anything exciting?
Second, I was a bit curious about how they work. I bought a multi-channel in addition to the single channel ones that came with the boards, but I cannot find much info about setup of how to use them (I suspect more documentation is incoming). Also, does each channel on the module attach to a pin, or can I use the multi-channel on a single pin?
Thanks for the tips and advice.
We are working on some more documentation including a garage door setup. But in the meantime. . .
Here is how to set up the DIY board for a 5V relay which can be used as Momentary Switch to trigger things like older garage doors - https://docs.konnected.io/security-alarm-system/wiring/siren/5v-hi-lo-level-relay-1
And here is the info on how to set it up to trigger a 12V item like a light -
One note: the only high level relay we sell is the single. The rest are low-level triggers and need to be designated so in the 'thing' in SmartThings. The single is the only one that should be used for alarms. Also if you are going to use the high level set it up on Pin R8. It is already set for high level triggers and will cause issues with low-level triggers.
Watch for more documentation oncoming . . .
Look at the specs on the relay. If it is low-level trigger you need to change the default in the Thing (settings gear in upper right corner). This should change this behavior.
You may want to look at this article. It explains a little more about how a relay works. Basically it's just a switch you can control. https://help.konnected.io/support/solutions/articles/32000022827-using-relay-modules-with-konnected
I would look at this article. https://help.konnected.io/support/solutions/articles/32000022827-using-relay-modules-with-konnected
Basically you would take the hot side to the Com on the relay (switch side). You would take a Wire out of the NO side of the relay to the sprinkler valve. Out of the valve you would go back to the Neg side of the supply (to complete the circuit). That's the basics.
However (I don't have hardly any experience with sprinklers). I've heard some value systems need to have 2 different parts energized to open. So it may take some experimentation.
The wiring I described would be from the AC transformer. It's would be independent of Konnected (Konnected is DC - DO NOT mix them).
Konnected would power and switch the power on and off. The current would running on the switched side of the relay. The link describes it in greater detail.
