Hi All,

I am wondering if such a device exists that can email me when it senses that it's input is either open or closed.

I want to use a comparator to monitor battery voltage and then trigger a latching relay when it's voltage hits 11V then get an email regarding it.

Not looking to build the network side of this hopefully there is something out on the market that can do this.

If you have a network/broadband at the site then a RaspberryPi might be an option. If you don't have a network connection look at GSM Modems - they can send SMS and/or access a website and so send an email, assuming there is a signal at the site.
