RTL_WMBUS:(1)

✨ rtl_wmbus:(1) — User Commands ✨

okay bestie, welcome to the manual page for rtl_wmbus 💖 it lives in section 1 (User Commands) of the manual, and it's a software defined receiver for Wireless M-Bus. yes, that's the whole NAME section, we keep it short and cute 🎀

🦋 DESCRIPTION 🦋

rtl_wmbus version 1.1.0-1 — that's the version, that's the vibe, no notes 💅

🌸 Usage ./build/rtl_wmbus: 🌸

here's the run-down, one flag at a time, no skips, no skimming, fr fr 🫶

• -o — removes the DC offset ✨
• -a — accelerate!! 🚀 (this uses an inaccurate atan version, so like… fast but not precise, iykyk)
• -r 0 — disables the run length algorithm
• -t 0 — disables the time2 algorithm
• -d 2 — sets the decimation rate to 2 (and yeah, it defaults to 2 if you just… omit it, main character behaviour honestly)
• -v — shows the used algorithm in the output 👀
• -V — shows the version
• -s — receives S1 and T1/C1 datagrams simultaneously. and listen, rtl_sdr MUST be set to 868.625MHz (-f 868.625M) — like, MUST must, no cap 💀
• -p [T,S] — disables processing T1/C1 or S1 mode
• -f — exits if incoming data stalled for 5 seconds ⏰
• -h — prints this help

🌈 Usage ./build/rtl_wmbus: 🌈

(yes bestie, it's the same list again — the page really does say it twice and I'm not about to gatekeep a single line of it 🎀)

• -o — removes the DC offset ✨
• -a — accelerate!! 🚀 (uses an inaccurate atan version)
• -r 0 — disables the run length algorithm
• -t 0 — disables the time2 algorithm
• -d 2 — sets the decimation rate to 2 (defaults to 2 if omitted)
• -v — shows the used algorithm in the output 👀
• -V — shows the version
• -s — receives S1 and T1/C1 datagrams simultaneously. rtl_sdr MUST be set to 868.625MHz (-f 868.625M) 💀
• -p [T,S] — disables processing T1/C1 or S1 mode
• -f — exits if incoming data stalled for 5 seconds ⏰
• -h — prints this help

quick reminder bestie: that -a flag is literally described as inaccurate, and -s only works if rtl_sdr is set to 868.625MHz with -f 868.625M. don't come for me if you skip those 🫶

and that's the page!! 💖 this was rtl_wmbus: 1.1.0-1, dated February 2026, and the manual name it's filed under is User Commands. slay, bye bestie 👑✨🌸
