JEV WiFi Analyzer
A 2.4 GHz WiFi site-survey instrument built on a ZimaBoard 2 and an Alfa USB adapter: Python and Scapy turn captured 802.11 frames into structured RF telemetry, and Jev reads each measurement window through OpenRouter to return coverage, congestion and optimization decisions.

Highlights
- Passively monitors 2.4 GHz WiFi on a ZimaBoard 2 with an Alfa AWUS036H adapter, Python, Scapy and Jev, with a terminal dashboard.
- Each measurement window sends structured RF telemetry (channel metrics, access points, RSSI statistics) to Jev through the OpenRouter Decisions API.
- Jev returns three decisions in one request: coverageQuality, congestionLevel from low to critical, and optimizationAction from none to hardwareAddition.
- The dashboard tracks Jev's coverage score, congestion level, optimization action and accumulated Jev cost; every window exports JSON to surveyExports/.
- Python does capture, count, calculate and aggregate; Jev does score, classify and choose.
Quickstart
bash
sudo -E python3 scan.py -c 1,2,3,4,5,6,7,8,9,10,11,12,13 -t 1 -w 30Watch out
README reviewed 2026-10-17; the device hops channels sequentially so they are not monitored simultaneously, RSSI is what the adapter sees at the sensor location, it is not a general spectrum analyzer, and it needs the specific ZimaBoard 2 and Alfa AWUS036H hardware.
Questions about this entry
Short answers drawn from the linked project or page.
A compact 2.4 GHz WiFi site-survey instrument: a ZimaBoard 2 with an Alfa AWUS036H adapter passively captures 802.11 frames, Scapy and Python turn them into structured RF telemetry, and Jev interprets each measurement window.
Each window's state (channels scanned, channel metrics, detected access points and window length) goes to Jev through OpenRouter; Jev answers three typed questions at once, coverageQuality as a score and congestionLevel and optimizationAction as choices.
A ZimaBoard 2, an Alfa AWUS036H USB adapter, a 16 GB USB flash drive, an HDMI monitor, a USB keyboard and an Ethernet cable, plus Ubuntu installed on the board; the analyzer switches the adapter to monitor mode automatically.
Install python3-pip and python3-scapy with apt and requests with pip, put an OpenRouter API key in scan.py, then run sudo -E python3 scan.py with channel, dwell and window options; press Q to quit.
At the end of each measurement window it saves a JSON file to surveyExports/ with the timestamp, window length, channels scanned, per-channel metrics, access points and Jev's evaluations, so repeated surveys can be compared for change detection.
It is not a general-purpose spectrum analyzer: channels are hopped sequentially rather than monitored simultaneously, and RSSI reflects the signal where the adapter sits, not the whole site.
Roni Bandini (ronibandini) built it under the GPL, and it is not affiliated with TypeSafe; Jev is reached through the OpenRouter Decisions API using ~typesafe/jev-latest.
