#433mhz

So, the nice thing about this sensor it is garden variety, 433Mhz, which means it can be received and decoded very easily by an SDR card. Since I have many of those, plugged one in, and installed rtl-433 (debian) (sudo apt install rtl-433) Run the app... and already able to read values! You can then log that to a text file, sent it to HA, draw pretty graphs, etc. etc. etc. #rtlsdr #433Mhz #sensors

The Radio Image Framing Protocol (RIFP) 1.0 is an experimental, extensible standard for sending images over low-rate radio links. The default rifp-cpfsk-4800 profile uses binary continuous-phase FSK and can be deployed around 433.92 MHz where local regulation permits it. RIFP itself is not tied to 433 MHz or to FSK and can be used in any frequency bands. I'm still exploring various low-cost options for a device that can receive and display images on an e-ink screen in emergency areas or similar environments.
