Devices with a poor connection

Connection info

The business devices connect to a Hub and the Hub sends the data to the cloud. When a device has a poor connection to the Hub, this can cause gaps in the data.

You can check the connection of a device with the Hub in the dashboard:

  • On the device page:

  • On the Status page when you click on the info symbol :

In general we define a good connection as a connection where the RSSI is between 0 and -85 dBm. Everything lower than -85 dBm can cause gaps in the data.

Recommended actions

  • Take out the batteries of the device and plug them back in. After a reset, the device will always connect with the "closest" Hub. (closest= The Hub where it finds the best connection with).

  • Move the device closer to the Hub. But make sure you still measure the air quality in the area you want to measure it.

  • Relocate the Hub and bring it closer to the device. Take into account that this will affect the connection with other devices.

  • If non of the above works/is possible, we recommend adding an extra Hub in the building.

Hubs with a poor connection

Power the Hub

Make sure the Hub is powered 24/7. When a Hub does not get power, it can not connect to the cloud. If a Hub is not online, sensors will disconnect from the Hub. So it is really important that a Hub is powered 24/7.

Cellular connection

When a Hub has a bad cellular connection, you can try to relocate it to a place with a better cellular connection. In general, these are places close to windows or outer walls (compare with your phone service).

If the Hub still has a bad cellular connection, we recommend connecting it over ethernet.

Ethernet connection

Generally, there is no need to configure the network settings on the Hub, but there may be some limiting factors on the network side (i.e. firewall). The Hub is using DHCP, port 443 for HTTPS communication to Cloud. Check your network settings and make sure the hub is able to reach the URL

The easiest way to verify this is by connecting your computer to the ethernet cable being used by the Hub and entering in the in your web browser address field. The connection should be OK if you get the text {"message":"Forbidden"} in the browser.

The following domains need to be whitelisted when you connect the Hub over ethernet:

Only adding HTTPS is sufficient.
