sure. well i am cheap. my neighbours arent. they have fancy stations like Bresser Weather. so why not share data like a proper pirate? i bought several rtl sticks by now. one i use in a pi/nuc/etc to just run https://github.com/merbanan/rtl_433 which has the excellent possibility to send the captured data over mqtt. so one line in terminal gives me weather data.

you could also grab flightpositions with the stick…if you share those you get even more data: https://www.rtl-sdr.com/rtl433-plugin-for-sdrsharp-updated/

still too boring? gnuradio could helpp find interesting frequencies and you might wanna google what they are for. you can also grab an send sensordata from busstationdisplay, temperaturecontrol of houses, tire pressure of passing cars etc. you could use that data in homeassistant/nodered or whatever to trigger alerts…like that police car is close by, shutdown shutdown… and so on. new cars are so chatty.
