M-Bus to wM-Bus Parser
This parser is utilized to parse messages from our M-Bus to wM-Bus solution. The solution is as follows: L-M-D (M-Bus to LoRaWAN) gathers the individual meter data a forwards them via NI-W-D2 (wireless M-Bus to NB-IoT) directly to the user.
This is especially usefull, if you want to gather wM-Bus devices along with M-Bus devices. M-Bus devices are encapsulated by a LoRaWAN M-Bus converter and collected by wM-Bus converter – which also collects all the data from native wM-Bus devices in the area.
Note that the M-Bus frames are encapsulated and encrypted in wM-Bus frame, but other than that, they are not modified or converted in any way.
For further details, please refer to this article on the M-Bus to wM-Bus encapsulation.
How to Use the Parser
The message arrives in a wM-Bus frame, which is a prepended and encrypted M-Bus frame.
- Enter the payload of the meter.
- Enter the key of the M-Bus converter, so the message can be decrypted.
- Confirm, you may now also parse the decrypted raw M-Bus frame in any other M-Bus parser.
Parser uses the tmbus library to parse M-Bus messages.
Usage
To use the M-Bus to wM-Bus Parser, enter a message and key in the following formats:
FF FF FF FF FF FF FF FF
FF, FF, FF, FF, FF, FF, FF, FF
0xFF 0xFF 0xFF 0xFF 0xFF 0xFF 0xFF 0xFF
0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF
