@sihui I just noticed that my sitemap file has the same problem. Then I found this thread in the forum: Bug since OH4: Why are the default.sitemap and *.things files not loaded on startup? (empty sitemap list) - #8 by somy
The fix from wezzix with the two commands to clean up the cache worked for me. Maybe the openhab-cli clean-cache command does not work anymore? I’m sure I’ve cleaned the cache with this command after the update.
