Another Unique Automation Project - Aquarium Automation

would those help?

This is one of the standalone automation devices that are out there, and pretty cool but I think I can do more with the ELK...

I might be back on track...let me throw this out there...

Here is a device that will control pH devices based on high/low ranges...it won't actually communicate pH values to the ELK but what if I used the AC outputs to communicate to the ELK that a high pH or low pH condition exists???? I could then easily write a rule to alert me or trigger a pump to start/stop. Is there a device out there that I could use to connect between an AC outlet and the ELK to report that one of these AC outlets is hot, i.e. an AC sensor? or perhaps I could build something with an isolation relay...

If you use sensors that, on their own, give a simple on/off indication based on a set threshold level, and so provide a switch-type open/close signal to the M1 zone, then you are good.

Just as you said Dave...this controller approach may be the 'good to go' method. Thx

It's common to use a wall wart driving a relay, or a PLC signaller, as a solution.

Got it...Thx.
