I might grab a couple of the metal fancy ones, since I think that the problems I had in the past were overheating related causing the tuner to die.
In anycase, tuning them to 315000000 also gets the little keychain remotes I got for some other purpose appearing in there as well, which is great.
Has anyone found any details of getting this running on a pi or something and sending the data to something useful? If I could get cheap 315MHz aliexpress motion sensors being recieved it would be a good alternative to the ugly bulky wemo ones I have at the moment.
Here's a simple tutorial which covers installing the drivers and sending the raw data over tcp (to a pc running sdrsharp). Running the rtl_433 tool wouldn't be that much more complex, as I believe it's based on the same tools. And that was just the first google result I clicked.
Someone a few posts above suggested some software that graphs and stuff (WeeWX). I think that can be installed on the pi, and used to upload it's output to a server over wifi. Though that's not motion sensor related.
If you want two sdr receivers in the same pi, then there's a model shaped to suit that. I'm not sure, might be one of the nooelec models. I can't remember.
