My ZSE40 4-in-1 Sensor is Unresponsive to My Z-Wave System

Here's what to try if your sensor keeps dropping off the network:

The ZSE40 4-in-1 Sensor is equipped with a Z-Wave Plus 500 Series Chip that enables it with longer range than regular Z-Wave devices; it can communicate with the hub 100 feet away if in open space with no interferences. However, most of us don't live in empty warehouses, so inevitably there will be "stuff" in the way that will shorten range, like thick walls, large furniture, and metal elements. Range will always depend on the specific structure of your house and the strength of your mesh network. If you're seeing connectivity issues with your 4-in-1 Sensor, here's what to try:

1. If there's a way to refresh your Z-Wave network, start with that first. Different hubs will have different words for this action (in SmartThings it's called Network Repair, in Vera it's called Update Neighbor Nodes, etc), but the effect should be the same. This should help configure your network and allow your hub find the most efficient communication route to the sensor.

2. Exclude  and re-include the sensor closer to the hub. If the device includes successfully and stay connected, the previous spot might have been out of range or there were too many interferences in that location.

3. Try excluding and re-including the sensor directly from the installation location. It's likely that the hub hasn't found the most best communication route to the device. This sometimes happens when you include a device near the hub and then move it away to be mounted. 

If none of the above solves the problem, please let us know! We're always here to help.
