This integration has now been retired, this release just reminds you to remove to the official integration.
With the 2024.9 release of Home Assistant the official Mastodon integration has been enhanced to include statistics, meeting feature parity with this custom integration. Therefore I will be retiring this integration and am now a code owner for the official one and will continue improving/maintaining things there.
How do you remove the custom integration and move to core?
Within Settings, Devices & Services, Integrations, open Mastodon Profile Stats.
Use the 3 dots to choose Delete
Then within HACS find Mastodon Profile Stats, and choose Delete to remove the custom integration.
Restart HA
Go to Settings, Devices & Services, Integrations and click Add Integration
Search for Mastodon and follow the integration steps.
Thanks to everyone who supported this integration.
