I’m trying to see if I can repurpose a couple of 345 MHz 2GIG devices (sensor and keypad) I found lying around, and read that a RTL SDR dongle could potentially receive both those ranges of radio frequencies (not sure how to set it up though). The other 928 MHz is for smart meters as I believe my water and electricity meters are on that.
Just wondering if something simple like this dongle could plug and play into HAOS and start to pickup those devices on MQTT or some other add on?
