Payload descriptions
A Tyness fitted with an M-BUS board transmits its data in raw format on the different LoRaWAN networks. The section below shows you how to decode the frames (Payload) sent by the Tyness. The following table describes the encoding of the data in
Settings
The board is configured with the Tyness Configurator software. Always use the latest version of the Tyness Configurator and check that your Tyness has the latest version of the firmware. If necessary, carry out an update. Step 1 ● Click on “Config” of the
Implementation
Above all, the Tyness and the board must be disconnected. The board must be installed carefully and with precision of the connectors on the locations EXT.1 and/or EXT.2 of the Tyness. The M-Bus bus cable of the type standard telephone cable – jYStY
