The ZSE18 Motion Sensor can be powered via USB OR battery. Below are the recommendations for both power supplies.
For the 500 series version of the ZSE18, you can only use the ZSE18 sensor powered by either battery or USB. Please do not power this version of the sensor with both methods at the same time, otherwise the device can be damaged. The battery in the ZSE18 cannot be charged by the USB - these are two separate power supply options.
For the 800 series version of the ZSE18, you can have both battery and USB power at the same time. The sensor will operate on USB, and fall back on battery in the event of a power outage. Please note, however, that the battery will be depleted within 24 hours of switching to battery, as it will still be operating as a repeater on the network.
Battery Powered
If you're powering the sensor via battery, you'll want a CR123A battery (3V).
If you've just replaced the battery in your sensor and find your unit is having issues, here are a few things you can try:
- Adjust the battery slot prongs to the middle to hole the battery tighter
- Some brands, like Panasonic for example, make their CR123 A batteries just a fraction of an inch shorter. This can cause the battery to fall out of the slot once the mounting bracket is installed (due to the magnet pulling it out).
USB Powered
If you prefer to have your sensor be an 'always listening' device, then you'll want to power it via USB cable and 1 A USB power supply.
Here are the accessories for USB powered sensors:
Connectivity Issues? If you've just mounted the sensor or recently changed the battery but find the sensor is having trouble staying online, then it may be a range issue. If it's located far away from the hub or if there are no other signal extending Z-Wave devices around, it can have trouble communicating with the hub. We recommend trying to add a Z-Wave signal repeater to your mesh network or utilizing Z-Wave Long Range with the 800 series version and a ZWLR supporting hub.
A signal repeater is any non-battery powered Z-Wave device installed in a location between the ZSE18 and hub. The hub can then use the repeaters to form a route to talk to the sensor.
Repeaters are not necessary to have, but if you find your Motion Sensor is having staying connected to the hub, then it could help with any range or communication issues.
If your Motion Sensor is mounted near the hub or has plenty of signal repeaters near it, then you can try these other troubleshoots under your hub specific folder.
If you have any questions or your ZSE18 sensor continues to have issues, please reach out to us! We'll be happy to help.
