I'd like to sprinkle my house with 1-Wire sensors (temperature - everywhere, humidity and flooding - in the basement), but the only wire already present in some locations is the power-socket (110V)...

Can the 1-wire microlan simply coexist with the AC power without short-circuiting and without the readings getting lost (that is, can I use the "white" AC wire as the 1-Wire data cable, for example)? If not, perhaps, HomePlug AV devices can be used as bridges?

Alternatively, maybe, the "interconnect" (red) wire of the Kidde-alarms (which we have literally everywhere) are usable for the purpose?

Thanks for any suggestions.
