Besides not using WiFi? If you want WiFi to work on your phone while lying in bed, then that requires Wifi signals in your bedroom. Also, remember that they are putting "smarts" into every appliance under the sun, including tea kettles. It is going to be a race to sell information about users from every manufacturer. Even if you go to zero smart devices, are your neighbors going to be less enlightened?
I don't know. I just want countermeasures against the dystopian technology we'll be facing in the future. If some device tries to image me or my home without my consent, they shouldn't get any useful information.
Maybe a signals jammer? Maybe some wall material that blocks signals outside our homes? Custom firmware for our WiFi access points to ensure they aren't doing this, or ensure that they do it in our terms and for our own use instead of some surveillance capitalism nightmare?
