1757 1757  The decoder for RS485-LN needs to be written by yourself. Because the sensor to which the user is connected is custom, the read device data bytes also need custom parsing, so there is no universal decoder. We can only provide [[templates>>https://github.com/dragino/dragino-end-node-decoder/tree/main/RS485-LN]] for decoders (no intermediate data parsing part involved)
