There are no additional charges after the initial purchase of the most common Wellntel systems.
A few customers may need longer telemetry distance than our standard gateway can provide, and in that case, cellular charges may apply. And certain larger scale farm systems may require ongoing maintenance for networking/maintenance of external information sources. But these are both special situations that won't effect most customers.
Moreover, Wellntel will not charge a service fee for information services provided to residential or small farm Wellntel owners.
Finally, the only ongoing cost a customer might incur is for replacement batteries to keep the system powered. Our Extreme Weather Battery Pack should last up to 10 months, depending on duty.
