The network related settings are on the 'Settings' tab of the commissioning interface. For the network requirements of the Sunlight Group EMS (firewall, ports, VLAN), see Advanced network settings.
The section "Network configuration" configures the ethernet port(s) and, on models with a modem, the mobile network. What is shown depends on the model of the Sunlight Group EMS.
| Setting | Explanation |
|---|---|
| Port mode | Internet port (WAN): the port connects the Sunlight Group EMS to the network with the internet router; this is the default. Separated network (LAN): only on models with a mobile network: the port serves a separate local network for the devices, while the internet comes in over the mobile network. The Sunlight Group EMS then acts as DHCP server on that network. |
| Network mode | DHCP client (default): the router assigns the IP address. Fixed IP: you enter the IP address, netmask, gateway and DNS servers yourself. |
| IP Address, Netmask, Gateway, DNS Server 1 and 2 | Only with a fixed IP. Enter the address of the Sunlight Group EMS, the netmask of the network, the address of the router and the DNS servers (for example 1.1.1.1 and 8.8.8.8). |
| DHCP server start and end IP address | Only in LAN mode: the range of addresses that the Sunlight Group EMS hands out to the devices on the separated network. |
On models with two ethernet ports, the second port can be Bridged with ethernet port 1 (both ports are on the same network, so the devices can be connected to port 2 and share the network of port 1) or a Separated network (LAN) with its own IP configuration and DHCP server. The separated network is the usual choice for devices that must not be reachable from the rest of the network.
On models with a modem, enter the APN of the SIM card as provided by the mobile operator.
Below the form, the section "Current IP config" shows the IP address and netmask that each port actually has, or "Not connected". Click "Apply network configuration" to save the changes.
Write down the configuration you apply. If the Sunlight Group EMS becomes unreachable after a change, see Troubleshooting: access to the commissioning interface. A factory reset puts the network configuration back to DHCP.
Only configure a fixed IP address if you have no other choice. It is recommended to keep DHCP and to let your router always assign the same IP address to the Sunlight Group EMS. See Fixed IP addresses.
The section "Network usage" shows how many MiB were downloaded and uploaded in the last 30 days. This is useful for a Sunlight Group EMS on a mobile data plan: the minimum recommended amount of data is 5 GB per month for less than five devices, plus 1 GB per additional device, and external control signals need considerably more.
The Data Saver reduces controller-to-cloud traffic by creating one-minute summaries and uploading them in batches. Local storage and local control continue, but the app no longer shows live readings and remotely changed settings are applied less frequently. Choose On or Off and select Save. See Data Saver for the full behaviour and timing, or Data usage for mobile data guidance.
The section also contains an internet test ("Do speed test"), which measures the download speed and the lowest, average and highest latency of the internet connection of the Sunlight Group EMS. Use it when the Sunlight Group EMS is slow to react from the app or regularly shows as offline: see Troubleshooting: network.
The remote service connection allows diagnostic services, updates and remote support by your distributor. It is strongly recommended to keep it enabled.
| Setting | Explanation |
|---|---|
| Enable remote service connection | Enables or disables the connection. |
| Service port | The port over which the Sunlight Group EMS makes the outgoing connection: the default port (1194), the secondary port (1192) or a custom port in the range 35000-40000. Change it only when the firewall of the site blocks the default port. |
Click "Apply change" to save. You may have to allow an outgoing TCP connection from the Sunlight Group EMS over the selected port in the firewall of the internet router, see Network ports for outbound connections.
