Linux servers since I was a teenager β ISPs, hosting, infrastructure. Programming from Pascal and assembler to working with AI agents.
I love electricity in every form β from home heating and dynamic energy prices to passive houses, which I'm passionate about. I also work with subtle energies as a lightworker: Reiki, Kundalini and other multidimensional energies.
Away from the keyboard I build things with my hands: custom furniture (wardrobes, fitted kitchens), tiling and general construction work. As a teenager I spent most of my time on a bike.
Since COVID started I go winter swimming in ice-cold water. Colds and sinus infections were with me for 40 years β now they are gone. The human body can heal itself!
TymOS β my main project: a super-fast, lightweight smart home on a Raspberry Pi, running my house every day.
Smaller tools from it:
| zehnder-comfoair-q-esp32 Control a Zehnder ComfoAir Q ventilation unit with an ESP32 and CAN bus (ESPHome) β permanent fan speeds, PHP control over REST, no extra Zehnder modules. | weather-widget Tiny 48-hour weather chart in one PHP file β temperature, rain (median of 5 models), snow, clouds and wind, readable from a distance. ![]() |
| pstryk-api Hourly dynamic electricity prices, usage and costs from the Pstryk API into MySQL / MariaDB or CSV β today + tomorrow, cheap hours, PV. | tge-rdn Polish Power Exchange (TGE) day-ahead prices into MySQL / MariaDB or CSV β Fixing I and II, continuous trading, tomorrow's prices. |
| energa-mojlicznik Hourly electricity usage from Energa "MΓ³j Licznik" into MySQL / MariaDB or CSV β import, PV export, full history. | blebox-energy-meter Local (no cloud) reader for the BleBox 3-phase energy meter, e.g. Pstryk β power, voltage and current per phase every few seconds. |
| technics-hifi-widget Technics SC-C70MK2 widget in one PHP file β previous / pause (mute) / next / stop, volume, what is playing, over the unit's undocumented local API. |
All code written by Claude AI β I bring the ideas and the direction.
