The previously announced deprecation and removal of the Raspberry Pi GPIO integration is concluding in Home Assistant Core 2022.6, which is only a couple of days away. This integration allowed users to configure binary sensors, covers, and switches hooked up directly to a Raspberry Pi running Home Assistant OS, without the need for any additional hardware. However, due to limited usage of this integration, and the work needed to maintain it, the developers of Home Assistant announced its deprecation earlier this year.
As was the case with other deprecated integration, the larger Home Assistant community picked up what was left behind and created a Raspberry Pi GPIO custom integration. If you are still actively using the official integration, now is the time to make the switch. The custom integration is available on HACS for easy installation, and the migration should be a straight-forward process.
