Wireless M-BUS Fork

[E-Mixer]

Hi everyone!

I'd like to share a native Wireless M-Bus receiver extension for Bruce, developed with Codex assistance.

It adds a Wireless M-Bus entry to the RF menu with:

• Passive T1/C1 reception at 868.95 MHz
• Device IDs, manufacturer information, telegram details, RSSI/LQI and hex data
• Interpretation of supported unencrypted data records
• Device overview export to SD as JSONL

No keys or decryption are involved.

I've tested reception on my LilyGO T-Embed CC1101 Plus, and it works very well. Broader testing across modes, meter types and SD functions would be welcome.

Precompiled firmware for the T-Embed CC1101 Plus:

Thanks to the Bruce developers for providing the foundation! Feedback, testing reports and suggestions for upstream integration are welcome.
