The role of the Space Hub
The Space Hub is the central component of the Airthings ecosystem, acting as the bridge that connects your Airthings devices to the cloud. Without power or a stable connection, the Hub cannot transmit data from your devices, which prevents their information from reaching the cloud.
The lights of the Space Hub
The Hub features three lights, all of which need to be lit for proper operation.
Troubleshooting the Space Hub
If your Hub appears offline or seems to have a weak connection, follow the guide below to diagnose and resolve the issue.
Check if the Hub is powered
The Hub must be powered on to function correctly. If it's not connected to power, it cannot transmit data from your sensors to the cloud, causing all connected devices to appear offline. Alternatively, devices may connect to another Hub if one is available.
Is the Hub powered on?
No:
Plug the Hub into a power source or try a different outlet.
If the power supply might be faulty, try using a power supply from another Hub.
Once powered, proceed to the next step.
Yes: Move to the next step.
Connection types
The Hub connects to the cloud via either cellular or Ethernet connection. When powered, it will initially use the built-in eSIM for cellular connectivity. When an Ethernet cable is plugged in, the Hub will attempt to connect via Ethernet and the cellular connection is disabled. This means that if the Ethernet connection fails, the Hub will not automatically switch to cellular as a backup. The cellular connection will only become active if the Ethernet cable is unplugged.
Cellular connection
The Hub can operate via cellular connection, but poor reception can hinder data transmission. The cellular connection will activate when the Hub is powered and no Ethernet cable is connected.
Does the Hub have a stable cellular connection?
No:
Move the Hub to a location with better signal strength, such as near a window or an outer wall (similar to improving mobile phone reception).
If the cellular connection remains unstable, consider switching to an Ethernet connection.
Ethernet connection
The Hub uses DHCP and port 443 for HTTPS communication with the Airthings cloud. Ensure that your network or firewall is not blocking this traffic.
Whitelist the following domains to allow proper ethernet communication:
hub-api.airthin.gs
hub-api.dev.airthin.gs
global-api.airthin.gs
Network testing for Ethernet
To confirm if the ethernet connection is functional:
Connect a computer to the same ethernet cable used by the Hub.
Open a browser and navigate to
https://hub-api.airthin.gs/If successful, you should see the message{"message":"Not Found"}, which confirms that the connection is working.
Below is a screenshot showing the confirmation message:
If the ethernet connection still fails, try connecting the Hub to another network, such as a private or home network, to rule out any network restrictions.
If ethernet connection does not work, consider connecting the Hub via cellular by unplugging the Ethernet cable.
