I needed a display for my outdoor temperature sensor which is connected to Home Assistant.
So I built one with a ESP8266, Lolin D1 mini with official OLED shield.
It features a WIFI connected OLED-display, with capabilities to display almost anything from Home Assistant.
I bought a couple of Sonoff S26 Wifi-plugs. These are built with an ESP8266 wifi chip and can be programmed with custom firmware.
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.
