trackerjacker VS urh

Well, instead of a teensy, the esp32 is sure a good bet.

But since you've got the Pi, the next logical step is to get an rtc upgrade and run chrony/openntpd and a backup dns cache. Why not? I mean its right there on the desk. Could add a quick binary clock for practicality.

Since you might now be dependent on the thing, its easy to add snmp for monitoring, hack in some rrdtool or whatever to graph your sit/stand time, maybe a serial connection to monitor your UPS power situation, and you get a free Pi-hole by now! Probably a little overkill to run wireguard on the thing, though.

Why stop there? Have it control some functional LED lighting[0] (Zack uses an ESP32 instead of the pi--must not care about clock drift. The biometric sensor is also a little expensive and uncomfortable looking.) with suntime[1] for a perfectly and coherently illuminated environment. For the extremely paranoid, yet lazy and obsessive (who does that not describe?) you can grab an extra wifi dongle with raw monitoring mode to have some fun with trackerjacker[2]. Use an innovative static base station running map mode, so when an influx of unknown devices with increasing strength and/or known vehicle SSIDs or PAN beacons are detected, just go full Red Alert (using those very practical leds) and score a quick win by raising the desk and commanding your IoT lighting for a deft escape. Maybe you can use this for the girlfriend too, you've already got rrdtool or cacti or whatever graphing the desk height, so you could also use that capability to gain insight as to when it should reach out and trigger your coffee maker's ESP32, certainly while raising the desk.

>> or somewhat expensive and complex SDR

I don’t think that’s as accurate today as it used to be.

On the hardware side there are tons of options very cheaply available - iirc the flipper uses the c1100 (or a number like that) it’s a popular cheap chip and it’s well documented and interfaces easily with arduino.

More accessibly, lime mini SDRs are cheap but there’s quite a few alternatives too.

On the software side GNU Radio is free with decent tutorials - we’re not talking anything like blender levels of difficulty to adopt even if it is a complex domain.

Although on the more accessible side, urh is incredibly powerful given how easy to use it is https://github.com/jopohl/urh

I used the latter to tap into a 2 channel wireless bbq thermometer via a $10 rtl sdr and that was a breeze, an absolute walk in the park compared to when I reverse engineered the flysky telemetry system.

Universal Radio Hacker on Github

you should check out Universal Radio Hacker

Check out URH.

URH can read flipperzero sub files and can export from wav to sub... https://github.com/jopohl/urh

Throw the recording at UniversalRadioHacker and see what it does with it!

I dont have much knowledge on decoding a signal from scratch but try URH - universal radio hacker here. It might be able to do what you need.

It's useful for transmitting digital RF signals to control household stuff, eg. ceiling fans or whatever. You'd want to also look into rtl-sdr and Universal Radio Hacker.

Tried tool https://github.com/jopohl/urh and it does not get too much information. I am expecting to find something similar to wireshark - it can detect protocols in traffic and highligh different kind of fields in packet headers.
