Home Assistant is open source home automation that puts local control and privacy first. Powered by a worldwide community of tinkerers and DIY enthusiasts. Perfect to run on a Raspberry Pi or a local server. Available for free at home-assistant.io
That's going to be a LOT of reading breaking changes.
That’s all I could think of. So many changes and things to repair
Honestly probably better to start from scratch. Backup yaml automations and scripts outside of Home Assistant and start over.
