Problem with switches (SW11-HK-1EU and SW11-HK-2EU)

Hi,

I bought the wall switch SW11-HK-1EU and SW11-HK-2EU at February 2021 and everything worked wery vell.

But, now I have a problem with wall switch. The homekit app don't show me state of switch, just show ,,updating" and do nothing.

If I tried restart wall switch, set configuration and I try add to homekit, is it problem with pin code (123-45-678), it doesn't work.

The wall switch firmware is version 0.3. Is it possible update for new version? (0.6 or newest)??

Please, can you send me new firmware and instruction how to install.

Thank you in advance

Mr. Jan Difko
