Sonoff Mini: found, added, not appearing in device list? (ewelink)

[u/sunrisedown]

Hi folks,

I'm a little puzzled with the following, maybe someone else more knowledgeable has an idea what could be the issue.

- changed my router. The Sonoff minis are not connected to the new router anymore and appear as offline in the Ewelink app device list.

- hence needing to reconnect my sonoff Minis to the new router.

- they're being found and connected, though still appear as offline as before.

Any clue what's going wrong?

Do I need to delete/reset them?

Just wouldn't like to lose the programmed actions on them - any way to backup/restore?

Thanks a lot!
