There is no standard installation! All installations are unique
The number and type of Devices being used and the environment and materials in the space
surrounding the Hub and Devices can impact the overall system performance.
For the best results ‘work around’ potential obstacles such as solid walls or metal structures. The
Zigbee network used for the AOne system needs to have a ‘line of sight’ to the AOne Hub or no more
than 3 Device ‘hops’ to get to the Hub. For optimum results, especially if there is a lot of metal,
Devices should be either less than 10-20m from the Hub or less than 5m between each other.
The Hub needs to be in as central a location as possible or where there are solid walls, multiple Hubs
would be better than designing a ZigBee network with multiple hops. The distance between Devices
and the Hub will need to be closer if the wall or ceiling between them are composed of solid material.
In particular placing AOne Devices on top or near to metal can reduce their Zigbee signal strength by
at least 20%. A Zigbee system will perform better in a large open space where the signals are not
being impeded.
When using a Zigbee network with ‘hops’ any Device that is switched off due to a manual switch will
potentially break some of the Zigbee network and routing so preventing Devices from working.
The number of Wifi networks in the same space will also
reduce the performance of the ZigBee network and may
require less distances between Devices and the Hub.
●
The signal from the Hub will be stopped by the solid
structure
●
Green area indicates a good ZB signal
●
As the distance from the Hub increases the ZB
signal will decrease and fall below an acceptable level as
