Nokeval flex sky radio (97956) wireless transmitter 433.05-434.79MHz

The Sky devices use the Semtech LoRa modulation technique that allows unforeseen wireless range in a battery powered transmitter. The protocol used is defined by Nokeval, called NLORA1, which means that the Sky devices are not compatible with the LoRaWAN infrastructure. By equipping any of the Flex measurement module with an Flex-Sky-Radio module, it can be used with the other Sky devices, e.g. the Flex-Sky-Link-RS485 receiver. The measurement module must have a firmware 2.1 or newer.Before using the 433 MHz radio, make sure it is legal in your country.
