On this tab you connect to the Radio Dongle. Choose the Radio Dongle (bc-usb-dongle) from the list and click Connect

Playground Device

After connecting to the Radio Dongle you could see all the paired wireless nodes. The node alias is later used in MQTT message topic (node/climate-monitor:0/..), so change it only when you know what are you doing.

  1. Disconnect power from the wireless node (remove batteries or Battery Module, disconnect the USB cable, remove DC jack from Power Module)

  2. Click on the Start pairing button

  3. Apply power to the wireless module

  4. Repeat with all the modules you want to pair
