Network connection

• Connection - Type of network connection
  • Connect to Wi-Fi - Connect the device to a existing wireless network
  • Standalone access point - Creates a standalone access point for you to connect to. Useful for a location where you want to track power consuption, but where there is no network available
  • Ethernet - Connect via wired network. This option is only available on devices equipped with the necessary hardware
• SSID - The name of your wireless network
• Password - The password to connect
• Power saving - Power saving scheme for WiFi. Default will be good for most devices. If you have a BUS powered device, Minimum or even Maximum may be necessary for stable operation.
• Power - Power output of the WiFi. Keep at highest number unless you know what you are doing. This can be tuned to lower power consumption even further or even to improve reception.
• Allow 802.11b legacy rates - Allows the device to use legacy data rates while connected to the Wi-Fi. This can consume extra power and also cause some level of connection instability, which is why this preferably is off.

Special notes on power consumption

If you have a BUS powered device (ex. Pow-U), your WiFi settings and other devices on your WiFi may impact power consumption of your device. If the power consumption gets too high, your device may reboot randomly. A good rule for these type of devices is to have a dedicated IoT WiFi with a low amount of traffic and the following configuration:

• 2.4GHz (No problem if combined with 5GHz)
• Roaming disabled (802.11r)

To lower the power consumption further, set DTIM to a number between 3 and 10, higher number means lower power consumption for client. This will impact throughput of your WiFi, so a lower number is better if you have devices on the same network that require some throughput.

Again note that other devices on the network can impact power consumption by keeping WiFi active (Apple TV etc)
