Is this actually an upgrade? - if I look at the first section of YYYYMMDD - it seems that the installed version is newer.
The reason I ask is that this particular light often has disconnects.
Is this a downgrade or an upgrade?
(the changelog only talks about v 1.14 so its hard to tell)
I can swear I saw a bug logged for this, but I cannot find it now, having searched mentions on the forum and the core GitHub issues.
To me it looks like HA is only looking for stable versions. While your installed version is newer, it is beta (rc1), so HA is trying to install the latest stable, which is older. I’ve seen this previously on several of my shellies.
