LuCI Remaining Traffic Monitor

简体中文

A web-based SMS utility for QWRT / OpenWrt with QModem. It uses native uhttpd CGI, does not depend on the LuCI dispatcher or sms_tool_q, and performs all SMS I/O strictly through tom_modem:

• Sending: Calls tom_modem -D -d <tty> -o s -p <PDU> using the AT port resolved from the selected QModem UCI section.
• Reading: Calls tom_modem -d <tty> -o r using the same AT port.
• Latest SMS: First saves the complete modem response to /tmp/sms_temp.json. It then starts from the highest index, collects consecutive fragments with the same reference, sorts them by part, and writes the result to /tmp/sms.json. The temporary file is removed after a successful operation.
• Parsing: Uses jq to parse /tmp/sms.json, and shows the latest SMS, remaining traffic, a traffic overview, and minute-based scheduled sending in the LuCI page.

Preset configuration

Set the actual PDU after installation:

uci set luci-sms-dataflow.preset1.pdu='YOUR_PDU'
uci set luci-sms-dataflow.preset1.name='Standard SMS 1'
uci commit luci-sms-dataflow

The four built-in presets are:

• China Telecom: 00010005810100F100000431182E07
• China Mobile: 0001000581100806F0000004633C9B0D
• China Unicom: 0001000581100100F0000004633C9B0D
• China Broadcasting: 0001000581100809F0000004633C9B0D

PDUs may contain hexadecimal characters only.

Set the interval in minutes on the page and enable the timer to enable the service automatically. Enabling it replaces the previous minute-based timer. Runtime logs are available through logread under the luci-sms-dataflow tag.

Build

SDK-free fallback package build

This project has no native binaries or kernel modules, so an architecture independent all IPK can be built directly on Linux or WSL:

chmod +x build-ipk.sh
./build-ipk.sh

The generated package is dist/luci-app-luci-sms-dataflow_1.0.11-1_all.ipk. Each manual or scheduled check sends the selected PDU, waits 15 seconds, then reads SMS messages and updates /tmp/sms.json. The traffic overview shows the file's last update time. Open it in LuCI under Services → Real-time Remaining Traffic Monitor, or visit http://<router-ip>/sms-dataflow/ directly.
