Hi, how do I get my HS200 switch to stop blinking when there is no router/wifi present in the house? I am selling my home and the new owner will not have a router (just uses his phone for all his internet needs). I know the constant blinking of the switches will annoy him and I'm not about to go uninstalling the 10+ smart switches. How do I get the switches to stop blinking when no wifi router is present/connected?

I read how to do this 3 or 4 years ago and it worked with a HS210 switch I didn't want connected to the router/app. But i can't seem to find that information again. I assume the same process will work with the HS200. Can anyone assist?
