Your first device, step by step
Connect a new device to WiFi, add it to your account and see the first readings. The steps apply to WiFi devices, such as the HAM ThermoSense, HAM DinMeter3P and HAM DinSwitchM.
Some devices do not need these steps. You add them only with the Device key:
- GPS trackers,
- Bluetooth (BLE) devices,
- devices that the installer already connected to WiFi.
For these devices, see Claim a device with its Device Key. For their installation, see Install a GPS tracker in a vehicle or Bluetooth (BLE) devices.
