Works great with z-Wave devices on a raspberry pi. I've got a few 433mhz sensors as well, integrated with all rtl-sdr. Also other raspberry pi devices taking to it via mqtt. Fun stuff.
- function_seven 5y agoI bought an RTL-SDR dongle years ago thinking I was going to do all sorts of awesome things with it. After my initial screwing around with it, it landed in a drawer for a few years. Well a couple of months ago I found this[1] and hacked together my own daemon to read my power meter and publish the result via MQTT. I then wrote a couple of sensors in Home Assistant to estimate my upcoming electric bill and the instantaneous power draw of my house. It's been rock solid so far. I've been surprised how much energy I use while sleeping in the middle of the night (something like 350W) [1] https://hackaday.com/2017/12/21/read-home-power-meters-with-rtl-sdr/ https://hackaday.com/2017/12/21/read-home-power-meters-with-...
- ThatPlayer 5y agoHow does rtl-sdr compare to say esphome and those cheap 433mhz receivers/transmitters? I remember playing around with those a long time ago, with arduinos and without esphome, with some outlets before wifi outlets became really common.
