Elorn Energy
I live on a Dutch barge, which can go off-the-grid. To support this, there are multiple sources of electricity: shore electricity, solar panels, fuel generator and batteries. This project aims to allow control and monitoring of all this through a Raspberry Pi.
It's written in Lua, supported by Mihini. A significant part of the project will be about supporting Victron Energy devices, as that's what I'm mostly equiped with.
It's all released under the MIT public License. So is Lua, and Mihini is licensed under the equivalent Eclipse Distribution License.
