As described in my previous picture, which name is the problem you are currently experiencing that you cannot control without the Internet? The premise is that the two devices are multi-controlled：bf81848eba964cfb31v1as、bf72dd9bbaed53110fqnfp。
I guess, first you can upgrade your gateway firmware to the latest version, since the gateways for your two sets of environments are not the same,and re-create a multi-controller relationship and tell me its name, if the problem still exists I can look up some information in the background to help troubleshoot the problem.
