Operator changed

I’m going to change my internet operator soon. There are many Sonoff devices in my electrical wall switch boxes. I’m confusing to open all switch boxes and reconnecting (pairing) the devices to new router.

Is there an easy way or method to make connection without open switch boxes? Does it possible pairing them on Ewelink ?

Thanks for help

Why not use the same SSID and passwords you used with the old router?

I think that, even if the SSD and password is same, it’s not working because of the router has changed.
But I’ll try. Thank you very much.

It depends on the security settings. Some devices remember the MAC address and so need resetting, but my experience is that my Sonoff stuff does not remember the MAC address so you can just use the same SSID and Password.

Thank you very much for you all. I’ll try.

I usually configure and create autmations my Sonoff devices before installing them on site by using any router with rhe SSID for the installation site.

There was a time. I even operated a Hub that controlled a site 1,000 miles away.

It will work.
