For indoor use, the Strips sensor should ideally be placed within 40m from the gateway and with no metal in the close surrounding to Strips. If you need to extend the network (e.g. Outdoor use) you are able to use up to 3 extenders (Z-Wave Plus certified extenders) that increase the range up to 150 m.
It is important to keep in mind that a poor Z-Wave network has an impact on any battery-driven device, so make sure you have a stable Z-Wave network once you install any battery-driven device in the network.
