What is wmbuster?

wmbuster turns your Flipper Zero into a passive wireless M-Bus listener, sniffing EU utility meters (heat, water, gas, electricity, heat-cost allocators) on the 868 MHz band with the built-in CC1101 radio. It captures RX-only frames in T1/C1/T+C/S1 modes, auto-decrypts AES-128 mode 5 payloads using keys from a CSV on SD, and shows live meter lists with RSSI bars, readings, and manufacturer details. Built in C for Flipper's ufbt toolchain, it's receive-only to stay legal for your own meters.

Why is it gaining traction?

Unlike desktop SDR tools like rtl_433, wmbuster delivers pocketable passive wireless recon—plug-and-play on Flipper with custom UI for scanning, sorting by signal/recent/packets, and per-meter details. Broad manufacturer support (Techem, Kamstrup, Diehl) plus SD logging and hardware AES make it practical for passive wireless site surveys without PC setup. Solid README with build instructions and compatibility reports hooks hardware tinkerers fast.

Who should use this?

Flipper Zero owners auditing their own passive wireless temp sensors or heat-cost allocators. Hardware hackers running passive wireless surveys in apartments or doing passive reconnaissance github-style on M-Bus traffic. EU utility pros needing portable passive wireless sensing over bulky SDRs.

Verdict

Grab it if you own a Flipper and relevant meters—RX-only design and AES-128 support nail the niche, with strong docs and tests despite 15 stars and 1.0% credibility score. Still early (limited field validation), so test your hardware first and file compatibility issues to grow it. (198 words)
