- Raspberry Pi with operating system (tested with Model 1B and headless Raspbian)
- Python 3 (tested with 3.10)
- Some python packages

List of all parts I used:

- Contactor to switch the three phases AC
- 5x1.5mm2 copper stranded cable
- Ferrules (for stranded wires)
- Raspberry Pi 1B + sd card

- Network switch & Ethernet cable
- Fronius PV inverter
- Fronius PV Battery (optional - Boilr will work just fine without a battery)

Unfortunately, the lid cannot be closed when there's something plugged into the power outlet on the hut rail. Thats why there is a second power outlet inside the distribution box.
Warning
If dealing with the electrical aspect isn't within your comfort zone, it's advisable to seek assistance from an electrician, as mishandling it can pose serious risks.
