Zigbee bindings remove

I have a problem with one of my Zigbee sensors so i have removed it from the Things page using the GUI.
However it will still show up when scanning for new devices even though power (battery) is disconnected from the sensor.

How can i remove the binding in Gateway version 1.0 ??
It seems to be different or have moved since previous version 0.12.0

Used to be able to do this in version 0.12.0-

  1. Stop the gateway
  2. Open ~/.mozilla-iot/data/zigbee-adapter/zb-xxxxxxxxxxxxxxxx.json
  3. Remove any nodes no longer want
  4. Save
  5. Restart gateway

Is there a new location for these files?

The new location is ~/.webthings/data/zigbee-adapter/zb-xxxxxxxxxxxxxxxx.json

Thanks mrstegeman,
i didnt think to check for a hidden webthings directory… oops!

To stop the gateway is it still-
sudo systemctl stop mozilla-iot- gateway
or
sudo systemctl stop webthings-iot- gateway ??

sudo systemctl stop webthings-gateway
