I have recently enforced a better privacy practice for my smart home devices, that includes creating a new access point for those devices and blocking them of internet access with VLAN.

Since then, my yeelight minas celiing lights goes unavailable whenever I physically switch them off and turn them on afterwards.

One really stupid thing is it needs internet access for using LAN control feature. it's really really dumb.

but at the same time, in this kind of age where everything wants to phone their home, i need to somehow mitigate this in every possible way such as by fooling the devices as if they have access to the internet.

Is this kind of things possible?

thanks!
