Communication Issues along the Z-Wave Network.
Z-Wave networks are mesh networks, meaning that most devices are able to repeat commands to other devices on a Z-Wave network. The best way to improve your Z-wave network functionality is to add repeaters. Keep in mind, Z-Wave devices powered by battery only do not act as repeaters. This includes devices such as Locks and TSTATS not learned in on C-Wire.
