I'm sure I've tried rtl_433 before, but looking at it again I'm super impressed by the lengthy list of over-the-air data protocols it decodes for weather stations, tire pressure measurement sensors, energy meters, water leak detectors, and so on and so on.

https://github.com/merbanan/rtl_433 or `brew install rtl_433`

Now, to dig out my RTL-SDR tuner stick + suitable antenna to try this out, and compare results with my #FlipperZero .

tnx @vees

I am using the "weather_station" app from the Unleashed firmware, which I think tracks the stock firmware pretty closely.

My only decode success so far is from an "Ambient Weather" station somewhere on my bike route. I have some Lacrosse transmitters but haven't successfully gotten them to read yet, tho it might be the tx is bad.

One thing to do with a #FlipperZero is listen for weather stations broadcasting on 433.92 MHz. Picked up one on my bike ride home, alas I do not have a good time stamp on the reading yet so I do not yet know where it was.

DAPNET pager setup seems to be working, up to a point. I'm seeing messages directed to the "us-mi" gateway (good), and seeing transmissions on my pi-star (good), but the Flipper Zero isn't hearing them (bad).

My best bet is that the pi-star is a little off frequency compared to the Flipper Zero and that I'll need to tweak the calibration. Time to get the SDR out to see what I can see.

If you are on DAPNET please page me at "w8emv" via "us-all" or "us-mi".

wait, my #pistar has #POCSAG tx support!

Ticket open with DAPNET, since it's entirely possible that I could make this all work once I get all of the accounts configured.

The POCSAG pager receiver for the Flipper Zero is from xMasterX and the code is here

https://github.com/xMasterX/flipper-pager

It's tuned by default to the DAPNET Web frequencies, which are in the ham 70cm band, on 439.987500 MHz.

There is a worldwide DAPNET network, but (alas) the closest existing one to me on the map is in Toledo Ohio, unlikely that I'll hear any signals from there.

Installed the "Dark Flippers" version of the Flipper Zero firmware, called "Flipper Zero Unleashed".

https://github.com/DarkFlippers/unleashed-firmware

So far it looks like a pretty good distribution - not a lot of visible UI changes, a bunch of additional applications, including a simple "spectrum analyzer" that expands into the 70cm band and a POCSAG pager receiver.

Now to read a bunch of documentation / mash some buttons to see what they do.
