Apparently, images load when I'm connected to the main router, they don't when I'm connected to the mesh wifi. So it's on my part, I need to research how to configure the mesh. Anyways, Thank you.
Update: Welp, suddenly it worked when I connected to the mesh wifi. Weird, I'll just monitor and see if it will still load the preview images later.
Shine, can you update your RJ01314344 to the latest version? It adds the scene gallery and your current links are close to be 1 year old anyways (they will probably expire in february).
Some other users are looking for it too, thank you!
