will send an alert when the voltage exceeds the level specified in your configuration. The Analog

The positive wires are the sensing wires or wires that detect the voltage changes and the negative
wires are for common ground. The positive wires are most commonly connected to solenoid wires
that drive ignition, horn, air conditioning, gas cap, door open/closed status, etc.
When the inputs are enabled, they will send an alert when the specified condition is met, and all
have the same electrical characteristics and behavioural options.
