I would like to suggest that the necessary dependencies for using SQL as a recorder will be included in the Docker image. It will make it a lot easier to use SQL.
It appears as though it was added, but I have no idea when. Iām on 0.87.1 and using Hassio. Recorder is connected and using my MSSQL server. When I first tried it, I got an error regarding dependencies, but upon closer inspection it was due to me specifying a database in configuration.yaml that had not yet been created. After manually creating a new MSSQL database for hassio, and restarting everything is working good.
