I'm looking for a simple device that would have a couple of DI's and hopefully an AI or two. This is simply for alarm monitoring. I've done this many times in the past with various methods including SCADA system or alarm dialer call outs and cell modem texting.
This case is a little different as the owner already has internet connection. We don't need the full fledged router or cell modem options. Simply monitor the single DI (to start with) and when it goes high or low, send an email.
Typically I'd do this kind of thing with a PLC but usually it's a bit more involved than this. Looking for canned solutions, I've found a lot of options, but they're all still overkill for the application. I'm looking for a pretty simple solution here. Any ideas?
