Wireless bidirectional transmission of digital and possibly analog signals over long distances of 10–15 km in free ISM frequencies and API management.

In recent years, the need to transmit signals or commands from and to remote locations without power supply or telecommunications infrastructure has increased significantly. The available commercial solutions are either excessively complex and expensive, or particularly simple with questionable reliability and without truly low cost.

For this reason, a basic, low‑cost hardware and software infrastructure was developed for wireless signal transmission using the LoRa protocol, without requiring a central signal‑collection infrastructure. The solution is currently in a prototype/development stage.

The system forms a network of encrypted messages between similar devices, where each device can communicate directly or through other devices (mesh). Information about signal states is transferred bidirectionally as data and through mapping (the state of the inputs of one unit is transferred as the state of the outputs of another, with confirmation – acknowledge). Access to the data and configuration is performed through a web‑based environment and API, utilizing the WiFi of the devices (Access Point, Station).

The energy consumption of the devices is extremely low, allowing operation for days with a small 80Wh battery and a ten‑watt photovoltaic panel.

A significant advantage is the user‑friendliness, as it provides the ability for immediate monitoring of signal status, transmission, and reception.

Such a solution, in its final form, can be used as a wireless remote I/O, for remote control or for wireless notification from locations without infrastructure to locations with infrastructure, such as electromechanical installations or control centers. Since the infrastructure is part of the device network, the information can be shared with involved parties or other systems, achieving optimal results in signal collection, control, and information distribution.
