EquipHours vs. Generac Mobile Link
Generac Mobile Link monitors connected units remotely and reports faults from the controller. It does not replace a maintenance log — it will not tell you when you last changed oil, which spark plugs went in, or whether Schedule B happened on time if you did the work yourself.
EquipHours works with any brand (Generac, Kohler, Cummins, Briggs) and does not require a cellular module. Log exercise cycles, Schedule A, dealer visits, battery replacements, and photos in one place. Free for two machines.
