SAN FRANCISCO (AP) — The first “smart” home gadgets that can be controlled by Apple’s Siri, the voice-activated digital assistant, are going on sale this week, just days after rival Google announced its own software for Internet-connected home appliances and other gadgets.

Apple announced its “HomeKit” project a year ago, but it’s taken this long for home gadget-makers to produce light switches, power plugs and wireless hubs that meet Apple’s criteria for compatibility and security.

The new products could be an important step forward for the concept of “connected homes,” in which appliances, thermostats and even door locks communicate wirelessly and can be controlled with a smartphone app. While other companies have similar products, analysts say Apple’s popularity could persuade more consumers to try them.
