A house-sized systems experiment.
Solar generation, battery storage, Home Assistant and TightWatt—built because understanding the whole route is more interesting than buying a sealed box.
The screens behind the experiments
These privacy-safe representative views use entirely illustrative data. They show the kind of controls, energy decisions and solar analysis behind the real system without publishing household details.
Other things I have put on the web.
Burdensome was the spark. After seeing their video premiere at the cinema I finally stopped putting off my own site and built TwoWaters properly.

Things I’m building
These are living projects, not polished products. They evolve when something breaks, when I learn something useful, or when there’s another signal, safety layer or edge case worth wiring in.
Solar + battery
Two independently tracked solar strings feed a protected 24 V battery bus, 4 kW and 3.5 kW inverter branches, and a separately controlled 40 A grid charger. Every useful path is measured, charted and argued with.
Follow the wires →Home Systems
Home Assistant joins 91 automations into one control plane; TightWatt ranks Agile slots against demand, solar and battery protection before the charger moves.
Follow the signals →Twowaters Fitness
One supportive view of activity, recovery, training, practical meal planning and a serious climbing journal—built around Apple Health and optional self-hosted data.
Explore the app →A galaxy that unfolds over days, weeks or months.
Create a private universe, share the invite code with friends and compete through mining, research, fleet deployment and persistent battles. Every game is protected by Microsoft sign-in.
Making the system more useful, not just more complicated.
The current workbench spans the live TightWatt 4.0 beta, live data for this site, and a tidier way to share the small automations that have earned a permanent place in the house.

Built for curiosity.
I work in IT, but this site is deliberately about the things I build for myself: hardware that earns its keep, software that solves small problems, and data that makes the whole setup a little easier to understand.
