If the range of your Zigbee coordinator is a bit disappointing, some sensors will be disconnected from your Zigbee network. Annoying, because you cannot receive information from those sensors. You can improve and enlarge the mesh through a device powered by 230v, such as a lamp. They also act as a Zigbee router and increase your reach and strengthen your mesh network, but it can also be done differently. With some cheap hardware and some free software.
