I own a Rika Filo pellet stove, which I like, but it is on the expensive side of the market and the Wi-Fi module to remote control it was a no-go. This article describes the way I reverse-engineered the radio protocol.
As it is my sole heating system and winter is coming, I wanted a non invasive approach to avoid breaking anything, so I hooked up a logic analyzer to record the commands sent by the micro-controller to the radio chip, which helped me to learn the RF parameters + actual payload.

Kongduino kindly sent me a WisDuo RAK3272s few weeks ago, it is a a breakout board for RAK nice module (RAK3172) around the STM32WL5 system on chip from ST. Let’s see how to use STM32 CubeMX to generate the initialization files and the LoRaWAN stack, then setup Visual Studio code debugger.

I recently bought a Sonoff Zigbee 3.0 USB Dongle Plus from iTead to use it with Home Assistant.
While it worked out of the box, the update itself was not complicated but you have to find the right tools…

I went down the hole of installing Linux on my phone (Samsung Galaxy S7). The easiest path is compiling and installing UBports, some people have heavily started the process but it is still a work in progress.

This is the first part: step by step description to build and boot the system, with helpers scripts to setup the system once flashed.

Small hacky script to set regular temperature changes in 3D printer gcode, to easily use “Temperature towers”.
