How do I update Grocy?

[jlafuenti]

Stupid question, but I haven't been able to find it on google...
My grocy instance that is from the Add on is running version 4.0.3
However Grocy in github is running version 4.2.0
How do I get the add on to pull the latest version?

There's no easy way to update from HA itself because there are a couple of layers in between --- it's the docker configuration in the addon itself which specifies version 4.0.3 (specifically, line 9 of grocy/Dockerfile), and Home Assistant can only update addons (which are self-contained docker containers), not the software within the addons. The latest stable release of addon-grocy is v.0.21.0, from January, which doesn't implement the updated grocy version. The current codebase for this addon does use grocy 4.2.0 and has since March (see #434), but until the next official release of addon-grocy, the official Home Assistant add-on won't implement that change.

If you're willing to take a step into the unknown, there is an addon repository which implements the development versions of addons, so it uses grocy 4.2.0. You can find more details on this repository here. Because the edge version of grocy is technically a separate addon (with a different docker ID) rather than an update to the stable version, it's got a separate docker container and you'd need to copy all your configuration and data over. Also, because it's a development version, there could theoretically be all sorts of broken functionality in it (in practice there shouldn't be much, because addon-grocy is just pulling in released software, even in its development version, but it could have mismatched versions on its dependencies or somesuch).

For my part, that seems like a hassle and I'd just as soon wait for the official release, which I hope will be soon, but if you really want to get to 4.2.0 now, there are options.
