Me, I like all the fancy lights and gizmos. I guess I just fit in that class of over complicating things.
JKB,
Check this out. It's from the Koiphen website of Koi pond enthusiasts. Think he has enough invested in equipment and check out those live feed monitors!
I bought a lot of stuff on ebay over the past for just such applications. Panel mount meters of every flavor. Sold a bunch of them already, and will probably boot the rest out eventually.
Right now, I have my eye out for a Red Lion G3 Series HMI. A G315C230 would be cool, but probably wont happen, so I'll probably just buy a G306A000 for starters. I put these on projects for customers quite often. Pretty easy to program, and they eliminate the need for all the other meters. I kept the sensors I have, and these will connect. These things talk to just about everything, has a Web Server, can call me up and I can remotely log into/control it from any place in the world that I can get an internet connection.
