Hello 
After using HA for many many months. I installed many integrations.
Somes of them, are unsed and i want to detect and remove them ( in order to clean my ha configuration ).
Is possible to detect unsed integration ( no automatisation, no integration that rely on ) ?
Thanks !
Not really as far as HA is concerned installed is ‘in use’ so you really need to be able to look at an integration and ask yourself why would I need that.
If you can’t answer immediately it’s probably a good candidate to be removed. Disable it and see what happens (disable will keep devices and entities in place - if it blows up after restart just re-enable it)
Take a backup before you remove something and if you pull it and something breaks… You have the backup for worst case restore.
