Just what the kitchen needs A fire in the kitchen at night. Smoke needs to drift into the smoke alarm in the hall before alerting people. Probably my kitchen is the most likely place for a fire to start. I have 4 sources of flame in my kitchen. Wifi linkage to other devices gives a chance of earlier escape from danger.
