You're almost there! All that remains is to setup the Liso units which this article will cover.
Check the following article for mounting instructions and possible power/network options.
Network configuration
The Evoko Liso can be connected via either a wired Ethernet connection or Wifi using a dynamic or static IP (support for configuring a static IP was introduced in firmware 2018_09_06_v2.0.029). By default, a Liso unit will automatically obtain an IP address using DHCP once connected via a wired Ethernet connection.
Setup in Default mode
To connect a Evoko Liso unit to Evoko Home (which connects to your booking system) you need to enter the IP address and port for your Evoko Home server on the Liso unit and then select the appropriate room in your configuration.
2018_04_16_v1.36.0 (or later), otherwise please update the firmware to ensure compatibility before proceeding.From the configuration screen press "Continue".
Select "Default mode".
Enter the IP address and HTTPS application port (default 3002) for your Evoko Home server. 
Wait for it to connect and load.
You can filter the listed rooms, this is especially helpful for larger installations.
Once the Liso is connected to your Evoko Home server it should display a list of all activated rooms in your configuration. Highlight the appropriate room and press "Select".
Now the Liso unit should be setup and ready to use!
The Liso unit should now appear under the "Monitoring" tab in Evoko Home.
