Safe Living Technologies RCS4 Remote Cut Off Switch Kit
from $350
Electrician-installed circuit shutoff for sleep areas, after assessing what must stay on.
Keep the modem or router you have if its radios can be fully disabled. Place network equipment away from bedrooms and long-stay seating, run Ethernet where it matters, and make any remaining Wi-Fi intentional and switchable. Wired listening when practical. Move power away from the body before buying anything shielded.
