Ok so here's the poll...
We need a standalone device that can send an email or SMS message on an external contact closure. It will connect to the internet via hard-wired ethernet. (Wifi may be considered as an alternative). It should be powered by 24VDC or 120VAC.
I repeat a 'stand-alone' device. No other PCs, PLCs or SCADA systems are on the premises.
I am looking for the lowest cost (time considered as well) device to do this. I have several ideas and several more expensive options at my fingertips, but I'd like to hear your input on a basic low-cost device to do this. Or maybe that's just wishful thinking
