You've included your sensor to Home Assistant, but it's not updating regularly and/or unresponsive to commands. Here's what to try if your device shows connectivity issues:

Your S2 Motion Sensor is a Z-Wave Plus device that has range of 100 feet (line of sight). Even so, interferences like large furniture, thick walls, and metal elements can shorten range. Ultimately range is determined by the specific structure of your home and the strength of your mesh network. If you're seeing connectivity issues, we first recommend healing your Home Assistant network. This function refresh the connections between your hub and devices so that the hub can find the most efficient route to each device.

1. Click on the Z-Wave Control Panel in Home Assistant
2. Under Z-Wave Network Management, click Heal Network

If healing the network didn't help get the device back get back online, here are some other things that may help:

1. Whether your unit is powered by battery or USB, try excluding and re-including the sensor directly from the installation location. Similar to the idea behind healing the network, it's possible that the hub hasn't found the most efficient communication route to the device; exclusion can help revitalize these connections. Every time you move the device, it's best to exclude and re-include the unit from the new spot each time. 
2. If that doesn't help, try moving the sensor to a location very close to the hub, making sure to exclude and re-include it from the new spot. If it connects successfully, the previous spot may have been out of range. You can then relocate the unit to a location that is between the original spot and the hub to see if it connects better there. 

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