Hi, do not know if is the right place to put this issue.
The idea is to enable a service based on pre-payment systel like Paypal.
In its essentials I'm thinking to enable a device such as Shelly1 PM upon
receiving a Paypal confirmation of payment, issued on qrcode scan and
pre-pay amount of money.
Just an example of this : Imagine a B&B site where a washing machine is
activated following a Qrcode scan and payment approval from Paypal.
As soon as the Paypal notification is arrived this info is taken into account
and passed to the device which turns on and remain active to complete
the washing cycle (2-3 hrs).
Same concept can be apply to Heating or Air Conditioners, Dishwashing
and other stuff.
Think would be useful for hosts & guests helping to reduce price for
basic service and have a pay-per-use for specific service.
Thanks
