Connect to WiFi - V3

Before you connect your monitor to Wi-Fi, here is some important information to consider:

  • Ensure port 443 (HTTPS) is open.
  • Ensure DNS resolution is not blocked for *.stat-temp.com.
  • Stat Temp Wi-Fi devices support 2.4 GHz networks only and will not connect to 5 GHz.
  • If band steering is enabled, it may need to be disabled for the device network.

  • Captive portals or login pages can prevent devices from authenticating and will require IT involvement to bypass.

    Allow TCP port 8883 outbound (MQTT over SSL) to the following:

    • Host: iot.stattemp.io
    • AWS endpoint: a2d9b7364deag5-ats.iot.us-east-1.amazonaws.com
    • IP addresses: 54.173.251.106, 3.221.75.93
  • Allow port 123 (NTP) to pool.ntp.org for time synchronization.
  • Avoid deep packet inspection or SSL termination that interferes with encrypted cloud traffic.
  • If a proxy server is in use, configure exceptions for Stat Temp domains.

Set Up Your Device

  • Unbox your Stat Temp monitor and sensor(s).
  • Place the sensor in its desired location.
  • Plug the device into power with the supplied power cord.
  • Turn the device on by sliding the power switch into the up position.
  • The monitor should have a QR code with "Let's Connect to WiFi" display.

Connect To Wi-Fi

As the monitor is connecting, you will see a status bar showing you exactly what is going on, so you get to follow along!

  1. Download the app ESP BLE Prov

  2. Open the ESP BLE Prov app on your phone and tap ‘Provision Device’.

    Grant permissions when prompted:

    • Allow camera access to scan the QR code.
    • Allow Bluetooth access to pair with the monitor.
  3. Scan the QR code displayed on your monitor using your phone.

  4. Tap ‘Pair’ to connect to the monitor via Bluetooth.

    A list of available Wi-Fi networks will appear.

    • Select your network and enter the password.
    • If your network is hidden or not listed, tap “Join Other Network” to enter the details manually.
  5. Tap ‘Provision’ to begin the connection process.
  6. Once provisioning is complete, tap ‘OK’.

The monitor will automatically restart and take its first reading. This could take up to 3 minutes.

Advanced Wi-Fi Configuration

Our Stat Temp hardware allows for an alternative method of network provisioning that does not require a separate application. This method is specifically useful in the following circumstances:

  • IP information must be manually configured
  • The wireless network utilizes Enterprise authentication/encryption
  • Connecting to a hidden network that is not broadcasting its SSID.
  • You have a large number of devices you are deploying
