Remote actuation of machines or machine systems is realized by a system for coupling a radiobeacon to a smart device and in turn to a broader network. The smart device is configured as a proximity-actuated “community nodal device” by an application that operates as part of the system.

Conventional smart devices generally discard data not addressed to the owner of the smart device.
