Winter is here in the Bay Area
Water sensors are small devices that can alert you whenever water is present around the refrigerator, the washing machine, sinks, and toilets—even in the basement. If you've got a leaky basement or appliances of a certain age, a smart water sensor makes for a strategic addition to your home.
Some smart water sensors work alone via Wi-Fi, and others connect to a smart-home hub; when wetness occurs, both can send a message to your phone so you can respond with a towel or a plumber. The units we're talking about here can't actually shut off the water; they simply alert you to the danger so you can respond quickly.
Though you can get a leak sensor that will set off an eardrum-piercing tone for as little as $10, if you want to get alerts and remote access, be prepared to pay a bit more. But the money is well worth it - an average water damage claim can easily cost $2500.
