I just finished the first version of a small software for managing the balcony solar plant of some family members. It works completely without any cloud or any other people's computers or even an internet connection.

There's three panels and an inverter with a battery. Any power initially is used in the household, then if anything is left it's put into the battery for later use, or if the battery is full, fed it into the public grid (to get a small financial compensation). Or if you want to, you can override that and just charge the battery, or even charge it from the grid.

Of course the inverter originally needs a cloud connection and comes with an app that needs a cloud connection and obviously is described as AI-powered very smart whatever. But there is a documented API for getting and setting some values! Interoperability! Without the cloud, there's hardly any logic built in. So I had to create it myself.

It's just a few HTTP requests, json, a SQLite database, and some very basic HTML.

My car is set to charge from 1.30pm to 5pm via Octopus Intelligent Go. I normally do a force discharge of my home batteries between 4pm and 7pm. This means it will overlap by an hour. Can I export and the car charge at the same time?

My home battery cannot see the car charger and the car will not charge from the home battery.

☀️ Our best April yet! We're thrilled to share our solar generation report. Record April production (610 kWh!) covered 91% of our house usage and resulted in huge savings compared to the new price cap. The West/North facing panels are now coming more and more into play.

I finally got our daily electricity cost graph working in Home Assistant! 📈 Plotly can be a steep learning curve, but a little Claude help made this visualisation happen. The biggest issue I had was calculating the export savings.

The solar production for March was 342.10 kWh which was surprisingly good. It is our second best March ever as you can see here.

It was going to be a tough compare to last years remarkable, 407.30 kWh
