Managing TCP Ports
Basic security firewall configurations will commonly allow outgoing connections from all devices, but high-security configurations may block all or a portion of this traffic. If your firewall is particularly restrictive, try adjusting your firewall’s policies to allow your Awair to make outgoing TCP connections on Ports 8883 and 443.
Your Awair uses one long-term secure communication protocol to send data back to Awair’s servers. After connecting to your Wi-Fi network, your Awair will open an ongoing TCP connection on Port 8883 to Awair’s servers, secured with standard TLS encryption. If severed, your Awair will continuously attempt to re-establish this connection.
Once per hour, your Awair will check for and download firmware updates when available. This check is done via a TCP connection using TLS security and HTTPS protocol, initiated on Port 443 to Awair’s servers.
All connections to your Awair are outgoing, no incoming connections are established.
MAC Address Whitelists
You can add your Awair to your network by whitelisting its MAC address (this method is sometimes referred to as MAC address authentication or filtering). You can find your Awair ’s unique MAC address on the back of your product, it’s the 12-digit number starting with “70”.
Whitelisting your Awair by MAC address is often the best way to connect Awair to managed login access points requiring secondary authentication.
