Successful startup will be indicated by a dull green glow on the LED. If the LED is off, or blinking a sequence, see the troubleshooting section.
After successful startup, you can connect to the device with your
web browser to access the configuration app.
Use the url:
http://iotawatt.local or, if your device
has been renamed, use
http://<newname>.local. The configuration app starts with a row of buttons:
Hover over and click in the dropdown menu.
You can change the
Device name to another 8 character name if you wish.
If you have more than one IoTaWatt you will need to do this so that they
each have unique names. When you press save, the IoTaWatt will restart using
the new name. From then on,
http://<newname>.local will be the url
that you will use to access the device from your browser, and the new
Device name will be the password that you must use to
connect to the AP if configuring for a different WiFi network.
