It is not clear that this is the app that will be used for the new watches. I imagine it will support the new RePebble watches, but I believe that app was intended for the original Pebble watches.
The thing that makes it so unclear to me is that this is a repo owned by the Rebble team, not the RePebble team. I do not know how much overlap there is between the two teams, but the RePebble team does not have any open source repos that I could find. Any mention of open source software by RePebble (including the OS) are links to repos owned by other teams, which is a little concerning.
I think that any guides you find for Gitea + Renovate should work still for Forgejo + Renovate.
I believe the process is:
RENOVATE_GIT_PRIVATE_KEY
(SSH private key value),RENOVATE_TOKEN
(Forgejo token value),RENOVATE_PLATFORM
(gitea
),RENOVATE_ENDPOINT
(Forgejo API base URL), and any other Renovate settings that you may find helpful/necessary to configure (eg:GITHUB_COM_TOKEN
,RENOVATE_AUTODISCOVER
, etc.)
