In many homes and holiday homes ZigBee products and sensors will work just fine without you doing any network planning. But in some cases it will be necessary to plan the network to ensure that the wireless components can reach each other. Concrete, glass or other distracting elements can weaken the signals between the devices in the network.
Power failure at home should also be taken into consideration so critical devices can communicate even when there is no power at home.
ZigBee is the standard for home automation and has good penetration in homes. The scope range for signals is according to vendors specifications for each device.
ZigBee uses mesh network, where all devices are “talking to” each other, directly to the HOMEGATE or through other ZigBee devices to ensure that the signals are getting through.
A ZigBee network will maintain itself and calculate what is the optimal route through other devices and to the centrally positioned HOMEGATE.
It’s wise to plan critical devices so they can reach the HOMEGATE directly or through devices with repeater and battery backup, in case of power failure.
Remember that it pays off to start the installation of components as close as possible to the HOMEGATE, and then work your way further and further away to other rooms or other floors in your home.
