Reset Knightsbridge CU9KW socket when WiFi won't reconnect, no mains access?

Hi Guys

I have several Knightsbridge CU9KW Smart 13A double mains sockets across my home.

Long story short - after Wi-Fi changes in the house (same SSID and password) - the devices won’t reconnect - seems like they timed out - and are sitting with both RED LEDS flashing.

Is there any way to reset them from the front switches rather than powering off the ring mains to make them reboot?

I have no reason to think they need reflashed as the only thing changed is Wi-Fi - and as I mentioned the SSID and creds have not changed.


Any advice most welcome - thanks

And hasn't the encryption changed by the way - used to not find my wifi smart homu elements for this reason....
Greetings. J.
