}Home Assistant
Home Assistant is an open-source home automation platform. I run it on a Raspberry Pi in my home.
Home Assistant controls my lights, and you can control it via the Home Assistant WebSocket API.
I built out the ./data-manager and ./hass-ws-client utils while playing around with Home Assistant a while ago. I thought it would be a fun example for an external tool. However, the Home Assistant code isn't the focus of this repository.
