Network conection
Network connection: Choose your network
The ECA Control system can be connected in two ways:
- Via the ECA Control’s Own Network – Useful for direct access when no external network is available.
- Via Your Home Network (Recommended), you can connect using Ethernet or Wi-Fi. Your device will be accessible as long as it remains within range of your local network. It allows remote access and seamless integration.
1. ECA network (Access Point Mode)
This is how the EVA Controller is delivered.
This option is suitable if the home network does not provide sufficient coverage around the pool:
- The ECA Control creates its own Wi-Fi network (AP Mode), allowing direct connection.
- The tablet connects to this network to operate the ECA Control.
- Expanding the home network’s coverage is not necessary.
- Your device will not be connected to the internet while using this network.
2. Home network (recommended)
These settings are for both Ethernet (wired) or Station Mode (Wi-Fi).
This option is preferred if the home network provides sufficient coverage around the pool:
- Once connected, the ECA Control will no longer broadcast its own AP network.
- The tablet remains connected to the home network while operating the ECA Control.
- Switching networks on the tablet is not necessary to control the system.

Step 2
1. Click twice on the gear icon at the top right of the screen to go to the advanced settings for linked EVA products.
2. The settings depend on the control version. You can read more about this in the chapter “Overview of the different controls.” The advanced settings are not available with the ECO version and is only partially available with the Essential version.
3. The lightning group is automatically switched off. Select in the app the number of groups at lighting groups and give recognizable names in Zones (block below). Only enter multiple zones when there are several light groups such as EVAstream Lamps, Jacuzzi Lamps, etc. NB! The first group is always the lighting group linked to the EVAstream. The lighting in this group automatically changes colour during the training program.
Controlling the lightning groups
The four lighting groups can be controlled on the following DMX channels:
Group 1 = DMX adress 001 (underwater lighting): channels 1 to 4 (When the lighting is set to these channels, it will automatically change in sync with the EVAstream.)
Group 2 = DMX adress 011: channels 11 to 14
Group 3 = DMX adress 021: channels 21 to 24
Group 4 = DMX adress 031: channels 31 to 34

FAQ
Check if a VPN connection is active on your device. If it is active, disable the VPN connection or configure it to allow access to local network.
The time setting in the web application (EVAstream mode) overrides the remote controller. This means if you set the time to 30 minutes in the web app, the remote will always follow that setting and switch off after 30 minutes. To extend the operating time, either increase the time setting in the app or set the time to infinite.
The blinking green LED indicates that the software on the EVA Controller PCB is functioning correctly.
The orange LED indicates DMX activity, it lights up when the EVA Controller PCB is transmitting DMX signals (master mode, rotary switch set to 0) or receiving DMX signals (slave mode, rotary switch set to 5).
If the pop-up doesn’t appear, please check the following:
- Make sure your device is still connected to the EVA Controller (Wi-Fi connection with AP######). Devices tend to switch automatically to the strongest available network, so move closer to the EVA Controller to maintain a strong connection. The problem can also be caused by the device automatically connecting to other Wi-Fi networks. Disabling automatic connection may help prevent this issue.
- If the pop-up still doesn’t appear and the EVA Controller network is not listed among available networks, forget the Wi-Fi connection to EVAcontroller AP###### in the settings of your device. Then reconnect to this network.
- If the pop-up still does not appear, open a web browser and manually enter ‘192.168.4.1’ or ‘evacontroller.local’ in the address bar to access the setup page.
If you’re unable to connect to the EVA Controller that’s connected via Ethernet, follow the next steps:
- Check whether if the Setup Mode displays the current date and time.
- If the date and time are not shown, turn off the controller and turn it on again. Then check the date and time again in the setup mode.
- If the time still doesn’t update, the network cable may be defect.
- Remove the Ethernet cable, switch the EVA Controller to AP mode and reconnect to verify if the connection works.
If your device can’t connect to the EVA Controller via Wi-Fi, even though the controller is connected to the network via cable. Check if both the EVA Controller and your Wi-Fi network are using IP addresses within the same range. If they are not on the same IP range, they will not be able to communicate.
If your network has been extended using APs (Access Points) to increase range, this can affect the connection if these APs are set to router mode, as they may assign their own IP addresses. A wired network is usually directly connected to the ISP (Internet Service Provider) router, which also assigns its own IP addresses in DHCP mode.
If the EVA Controller page doesn’t open on your iOS device, check your firmware version. Apple’s iOS 17.4 does not support PWA (Progressive Web Apps), which are required for the page to work properly. To fix this, update your device to a newer iOS version or try to access the page on a different device.
If you’re unable to save the settings and receive an error message, it is due to the DNS Server field. By default, this field can be left empty. However, in case of an error, enter the IP address of the default gateway. If that doesn’t resolve the issue, you can also try entering ‘8.8.8.8’ as the DNS Server address.
Right now, upgrading your control is not possible. Once available, you can access this option through the settings menu (the star icon in the top right corner).
To connect to the EVA Controller via Wi-Fi, the rotary switch on the EVA Controller version 3.1 must be set to 0 in master mode. For earlier board versions starting from version version 2.0 with firmware version fw1439 or higher, the rotary switch must be set to 000. You can turn the rotary switch using a screwdriver.
