Hi unknown neighbor. Your weather station is my weatherstation thanks to rtl_433. Thank you.

#sdr #rtl_433 #rtl_sdr #radio

me: *pipes rtl_433 output as JSON into a Python script*

Python script: *crashes and exits after an hour due to a network error*

rtl_433: *continues on as if nothing has happened*

Sure, ignoring SIGPIPE is definitely the right course of action here. 🙄

I'm trying to receive a weather station at 868.3 MHz as well as some heat cost allocators and water meters at 868.95 MHz, both via #rtl_433.

Up until now, I did this using

rtl_433 -f 868.3M -f 868.95 -H 15 -s 250k -Y autolevel -Y magest -M noise -M level

i.e. frequency hopping. But shouldn't I be able to capture both frequencies simultaneously with a higher sample rate? But with "-f 868.3M -s 2M" nothing shows up anymore at all.

Edit: Solved! https://chaos.social/@scy/113068997126643230

@quanten Okay, with a sample rate of 1 M (-s 1M) and manually specifying "-Y filter=20" as suggested in the GitHub issue, it appears to be working now! Thanks a lot for pointing me into the right direction <3

So, I figured out how to use rtl_433 to receive the signal from my little weather station on the roof. Then discovered I was also getting the neighbor's weather station as well as occasional pings from elsewhere.

The interesting part is: the explanation for the difference in signal strength for the neighbor's weather station (blue line) from 8:45-11:30 today is that my civic was not parked in the garage on the other side of the wall from the antenna.

Welp! Turns out the wireless temperature sensor won’t report higher than 140°F due to a sanity check in #rtl_433. Fortunately the wired temperature sensor tracked the temperature all the way up to 164°F today. And it wasn’t even sunny all day!

Schöne Sammlung was man so aus dem Netzwerk rupft :D
#ThinkCenter #pihole #iobroker #rtl_433

Und da fliegt der Pi raus. Auf nimmer Wiedersehen, bye :D

Immerhin hat er jetzt glaube gesamt 4 Jahre das Pihole gestellt und nicht eine SD-Karte gefressen.

Im Zuge von der Umstellung von einem Pi auf ein #ThinkCenter Tiny.

Werden neben dem #pihole dann auch der #iobroker umziehen von seinem alten hp tiny pc.
Evtl. auch der letzte aktive Pi der mir dank #rtl_433 die Wetterstationen der Nachbarn ausliest :D

Mal schauen was man noch schönes auf die Möhre werfen kann danach.

Was man nicht alles noch mit einem alten i5-6600T und zukünftig 16Gb ram so alles mit den Dingern machen kann :3

Indoors I also use several Aqara #Zigbee sensors and #Zigbee2MQTT to get the data into #HomeAssistant. Placing one of those (indoor) sensors outside wasn’t all that successful.
Now I have a Lacrosse TX141W weather station outside that transmits on 433MHz and use #OpenMqttGateway running on an #Esp32 #LoRa board to receive those messages. There many sensors that are supported by the #rtl_433 and #rtl_433_ESP libraries that can be used.

I've been running #rtl_433 for a few days now, logging all the data, just to see what else I can read, and besides THREE weather stations, I've also found a couple of "TPMS" devices - Tire-pressure monitoring systems. These sensors have been mandatory in all new cars for almost 10 years now, and as it turns out they use the same 433MHz frequency as all these other systems.

Meaning, I can listen to my car's tires reporting their pressure every ~2 minutes, and when the transmissions stop, the car is no longer home!

If this works reliably will depend on your car, as the reporting times change drasically between brands. Some tires seem to have a standby mode that'll report only very spordically when the car's parked, but it seems I got lucky.
