Freespace 2 comes to mind. The whole game engine was open source not just the game itself. Looks like there is still a community building on it too. https://scp.indiegames.us/

I always thought it hinted that it was the Song of Growing that the Da’shain Aiel used to sing with the Ogier and the Nym during the AOL.

I would love to hear more about your setup and build. How are you using the heat, and what did you have to build to make use of it?

The private space sounds interesting. I wonder how it works in practice. Can any app be stored there?

exactly, i use https://iotawatt.com/ to monitor at the breaker box. Integration works well with HA

I have the circuits for all my “dumb” appliances monitored by my homeassistant. Then HA sends notifications to my phone. And it doesn’t need to send 3.6GB to the internet to do it.
