A "Smart Meter" sends its data back to BC Hydro once each day. It takes about one minute of transmitting time to do that. The radio signal is emitted away from the wall, not into the home.
The device doesn't emit anything except during that minute. The exposure of a homeowner to RF energy from the Smart Meter is miniscule - far below any established standards for safe levels.
I'm sure that BC Hydro will want to impose "time of day pricing" eventually, and that might be worth protesting. But worry about exposure to radio waves from the Smart Meters is groundless.
