UPDATE: We will be shutting down https://farmos.app at 2022-02-22T04:59:00Z, in preparation for Field Kit v2. Users who are currently using https://farmos.app to connect to a v1 farmOS server must migrate to https://v1.farmos.app before then, or will lose any data that has not been synced with that server.
See the instructions at the top of this post for more details on how to migrate.
