I had three broken rear LED lights on my BMW F25! I found a easy and cheap fix, resolder one resistor on every driver, and they all worked again!
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.
I had connection problems with my Raspberry Pi, it dropped connection over IPv4 periodically.
My solution was to disable IPv6, and the Pi’s network connections (over IPv4) went stable!
I have several Tactix organizers 16″.
They are fantastic assortment boxes! But one problem I encounteres is that the smallest bin (49x49mm) is sometime too big. I found one 3D-model of a 49x49mm with two compartments, I liked the idea but didn’t quite like the design with the wings… So I decided to CAD my own!
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.
