Hi Radio Gurus,


I am new this topic and recently purchased RTL-SDR, excited to use it. I am from Software background.

I have a new water meter which using Radio network to emit pulse details I want to read it to create a dashboard to watch on usage :) via it's FCC id I came to know which range it uses but not sure how to use it to identify which range it is out of given ranges and how to read the data it emits?

Thanks!!

I had a look around, but sensus water meters appear to be encrypted, so decoding them probably won't ever be possible.

See this discussion:

Thank you for your quick reply, that means it is impossible to read?

Curious to know if we have range of RF we can atleast tap in to encrypted data to see if that can be decrypted?

If it's encrypted you won't be able to read it. The range is probably a few hundred meters.

Encryption is possible, but I believe that it is a standard ASCII files by default. Should be something like meter ID and current gallons.
