Connect to WiFi - V3
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.
Before you connect your monitor to Wi-Fi, here is some important information to consider:
- Does the web connection require users to enter information on any type of captive portal/login page? This can block our devices from successfully authenticating. This will require IT involvement.
- Our Wi-Fi devices only support 2.4GHz networks. These devices will not connect to 5GHz networks. If bandsteering is enabled on your network, you may need to disable it.
- Confirm these ports are open:
- TCP Port 8883 outbound (MQTT over SSL), destination address: iot.stattemp.io,
- IP addresses
- 54.173.251.106 and 3.221.75.93
- Port 123 (NTP), host: pool.ntp.org
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!
Connect to Wi-Fi

What to Do if Network Configuration Fails Due to Incorrect Credentials
If incorrect Wi-Fi credentials are entered during setup, follow these steps:
- Choose an Option on the Monitor Screen.
- If You Select Retry, the device will restart.
- You’ll be able to scan the QR code again and re-enter the correct network credentials.
- If You Select Save, the incorrect credentials will be saved.
- The device will not restart and will remain disconnected until reconfigured manually.
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
