In some implementations, one or more “spokesman” nodes operate as a smart home controller. On the other hand, the devices that are battery powered are the “low power” nodes. These nodes tend to be smaller than spokesman nodes and typically only communicate using wireless protocols that require very little power, such as Zigbee, ZWave, 6LoWPAN, Thread, Bluetooth, etc. As described, in some implementations, the smart devices serve as low power and spokesman nodes to create a mesh network in the smart home environment 100. In some implementations, individual low power nodes in the smart home environment regularly send out messages regarding what they are sensing, and the other low powered nodes in the smart home environment—in addition to sending out their own messages—forward the messages, thereby causing the messages to travel from node to node i. e.

It sets off an alarm faster than a photoelectric or optical beam smoke detector once it detects fire. Therefore it is best used to detect smoke from fast flaming materials like paper and wood. It is also cheaper to manufacture. Compared to photoelectric smoke detectors, it consumes less power so a small battery can power it for month and is independent of external wiring. Since ionization type smoke detectors can detect particles smaller than smoke particles, they are prone to false alarms. Ionic smoke detectors use a radioactive isotope americium 241, and rules on proper disposal vary in each region.

From there, just plug a lamp, a coffee maker or anything else into the smart plug, and you'll be able to integrate that device into your smart home.

It is best for rapid smoke detection is crucial like in a room filled with combustible chemicals and gases, and even tobacco.
