I believe Standard 600EFs had variations of that capability via the serial connection optional cabling. I am not sure if their latest product still does though. A database IT wizard could very possibly poll hopper levels & provide a level warning remotely on a remotely controlled
app.
It seems like at minimum ... if a hopper runs out of
coins ... any
changer out of service could be hooked up to an alarm system. Some alarm systems nowadays can then call &/or text from their internal sim card setup. Too bad the USA cell companies tend to all have a monthly minimum vs just based on the few 15 second activations from an alarm system.
