This is my second RFLink hardware build. If you missed part 1, check it out here: How to make a $4 RFLink for 433MHz home automation!
The goal with this project was to build a small and neat RFLink dedicated to only be used as a gateway for 433MHz radios. But with full functionality, which supports the entire firmware.
This is how I made an poor man’s RFLink. It cost me only about $4, this is when I count in basic parts I already had, Arduino Uno, bradboard and some pin headers (but who doesn’t have this stuff in their hobby shelf?😉)..
This is my first LUA-script for Domoticz. I have a TV-bench where I have all my media devices, media-computer, av-receiver and game consoles…
The bench is rather small, which led to it become very hot in it. My solution was to mount PC-fans to ventilate out the hot air.
To control my fans I used a 433Mhz switch. I also added a temperature sensor and wrote a small thermostat script for Domoticz.
