There is a device in my house that is broadcasting in the 450MHz - 2.4GHz range. I do not know the exact frequency that the device is broadcasting on. I am looking to use my raspberry pi to receive and decode the signal. Is there a module that would work for this radio signal range. I see there was a question asked about receiving the FM frequency range, but I am looking to receive a higher frequency range. Receive FM Radio on Raspberry Pi

I could try the RTL-SDR solution if there is no other solution, but the range doesn't quite reach 2.4GHz

  • what is the transmitter device? ... is there no label on the device? – jsotola Dec 12 '20 at 23:31
  • I found the frequency information for two of the devices Water: https://sandeen.net/wordpress/energy/neptune-rf-water-meter-frequency-hopping-pattern/ Electric: http://ewwwsv2.elster.com/downloads/Type_AB_data_sheet.pdf – jdeyrup Dec 12 '20 at 23:46
  • I can't find as much information the two gas meters: http://www.aplisac.com/pdf/AMERICAN%20METER-Catalogo_General.pdf Possible frequency for other gas meter might be same as their frequency for water meter https://www.reddit.com/r/RTLSDR/comments/b18jht/anyone_get_readings_from_their_sensus_water_meter/eiklsyi/ so maybe I can use the RTL_SDR dongle – jdeyrup Dec 13 '20 at 00:03
  • i think that those devices use encrypted communication ... where are you seeing the 2.4 GHz rating? – jsotola Dec 13 '20 at 01:22
  • That is frequency range that I found when googling for the frequency range of AMR devices https://lakecountry.civicweb.net/document/36903 The devices might be encrypted, but it seems like other people have been able to decode the data; so I am assuming that it is not encrypted for all devices – jdeyrup Dec 13 '20 at 02:02
