I think I described it wrongly. So I have the second hub now.

So if my smart button s200 is paired with 1st hub and for example my smart switch s210 is paired with second hub then automation between s200 button and smart switch s210 won't be controlled locally by hub.

I see that automation have to go through the cloud, so if internet will be down I won't be able to control s210 smart switch with my button.

Button is paired with hub number one, and switch is paired with hub number 2, I thought it still could be controlled locally through local WiFi because I can control sockets locally.

Thank you, that's explain everything.

Are any plans if it possible to make two hubs talk locally so automations from devices connected to different hubs (hubs, etc. connected to same WiFi network) will work locally?

Thank you again.
