Device communication problems
Access to the commissioning interface
When I go to "Controller Configuration" in the app or online portal, it says that the controller is offline.
Steps to undertake:
- Check the internet connection of the Sofar EMS. Check with your computer if you have internet on the ethernet cable attached to the Sofar EMS.
- Try scanning on the local network for the Sofar EMS with an IP scanner (see also "").
- Check with the building owner (residential) or network administrator (commercial) if this is a network with fixed IP addresses. The Sofar EMS is by default configured to use DHCP. If you need to change it to a fixed IP address, first connect it to a DHCP network, and change the IP address from there to the necessary fixed IP address.
- Check if communication over the right outbound network ports is allowed. (See also "")
- Verify if the have been followed.
- If the Sofar EMS is on a 4G connection:
- Check the 4G reception of the router. (Note, it can be on another mobile network than your phone).
- Place the router or 4G antenna on another location.
- Check if there is enough data in the 4G connection bundle. It is recommended to have 5GB/month available for up to three devices, plus 500Mb per additional device
