I’m not sure how you guys would feel about this… but I have a SDR connected to my Unraid server and found that a neighbor has one of those Acurite 5-1 weather stations that I can pick up on a 433mhz signal, parse the JSON file and added it to my dashboard. If you have a SDR sitting around you could scan your area and see what you get.
I second using an SDR with 433MHz devices. Incredibly reliable and low power.
Been using a nooelec SDR and one of these sensors:
Geevon TX10 Wireless Remote Outdoor Sensor
Never thought of this approach.
So, what is it transmitting? Text? Or some form of numerical data?
I mean, how do I start? 🙂
Most people run rtl_433 to decode radiofrequency signals.

0’s and 1’s are encoded with increases and decreases of amplitude of the carrier frequency, as in AM radio.
