Give user the ability to downgrade individual addons

[mwav3 (Tim)]

There have been several instances where updates to an addon broke something. The developers of the addon may add a new and very useful feature, or patch a security issue, but unintentionally create a bug. Or, there is no bug but a breaking change broke something on one’s setup and they need time to sort it out. Currently, there is no way to downgrade an individual add on other then restoring an old snapshot. If you didn’t do a snapshot, or made other changes since the snapshot, you’ll be stuck or lose those, and will need to wait for the patched version to be released.

Several recent examples where this can be beneficial are linked below

ZwaveJS2MQTT / Debug message - #9 by mwav3 Is there a way to downgrade ESPHome? Portainer v2.6.2 - unable to start containers All controls (switches, shutters, etc) stop working after a while - #6 by mwav3

Not being able to “downgrade” an addon that causes a problem is a real deal breaker for me on using a supervised install, and one of the reasons I use Home Assistant container

This is very similar to a FR I submitted:

Feature Request: Allow update and back-level integrations individually

Most people depend on multiple different integrations in their HA system. These integrations change all the time (which is good.) But the testing is, by its nature, very difficult for one developer to do. There are so many different environments out there, it’s almost guaranteed that fixing one bug or making one update will introduce another problem for some users. Lately it seems these bugs are creeping into merged integrations more and more. I use one integration which was changed in version …

Sorry didn’t see that one when I searched, although yours is a bit broader then just the addons. I think just the addons might be a bit simpler to get going first, since they’re docker based containers. I went over and voted for yours too though.

I believe you can downgrade addons with use of update command providing addon exact version

How to downgrade addons?

How do I downgrade an addon? There seems to be no way of downgrading to an older version of an addon, when some addon doesn’t work.

Are you referring to this post specifically? I was unaware that those steps would work to downgrade.

How to downgrade addons?

Based on what I have learned here’s something that seems plausible (but I have not confirmed it yet). What if you want to downgrade an Add-on but don’t have a backup of it containing the desired older version? Make a partial backup containing just the current version of the Add-on. Open the tar file that was just generated and find snapshot.json. Modify the contents of snapshot.json. Change version to what you want. Save the changes and attempt to restore this altered backup file. For example…

Has anyone actually tried it? I can’t since I’m not running a supervised install at the moment (although I can give it a shot on my test install)

Still feel many would be lost editing the json and being able to downgrade from the UI in the Supervisor tab would be ideal.

The way to downgrade an addon is by doing a partial restore or a previously created backup.

All other ways of doing it will cause issues.
