How to Update Liso Firmware to Match the Liso Home Version
When you receive a new Evoko Liso panel, the firmware may not be up to date. In some cases, this can lead to compatibility issues. As a best practice, we recommend updating the firmware to match the version currently running on Evoko Home.
There are several methods available for updating the firmware, each suited to different scenarios. Below is a brief overview:
- Remote Update – Ideal for devices already connected to the network.
- USB Update – Useful when remote access is not available.
- Firmware Reset – A complete reset that reinstalls the firmware from scratch.
Remote update
This is by far the easiest way of updating the Liso firmware, since it's done remotely from within Evoko Home.
There are, however, a few conditions:
- Only default mode is supported.
- Evoko Home will need internet access, or you will need access to the file system of the Evoko Home server.
- The Lisos need to be connected to Evoko Home and appear online in the Monitoring tab.
If any of these conditions are not met, you can not use remote update. In this case, we recommend a USB update instead.
To perform a remote update of all Lisos connected to Evoko Home:
For Evoko Home 2.x:
1. Go to Rooms -> Monitoring
2. Click Firmware Check
3. If a new firmware is found, click Confirm to download it.
4. When the button has changed from "Loading...", the firmware is ready to be transferred to the devices.
5. Click the green arrow button in the header to update all devices that can be updated, or click the same button on a device row to update that device.
To load firmware from the local file system instead of our update servers, go to Global settings in Evoko Home and change the Firmware search location from Remote to Local:
Then download the firmware manually from https://download-liso.evoko.se/ or Biamp Download and place it in the liso_files subfolder, located under the Evoko Home install folder.
USB update
Performing a firmware update via USB is also very simple.
1. Download the Evoko Liso firmware file from https://download-liso.evoko.se or from Biamp Download
- For 2.x: Unzip the zip file and place the two files in the root of a USB flash drive. The .tar.gz file contains the firmware, and the .tar.gz.sig file is used by the Liso to verify the firmware.
2. Insert the USB stick into the USB port on the back of the Liso
3. To perform the update:
- If the Liso is unconfigured, press the "Upgrade via USB" button.
- If the Liso is already configured, log in to the admin section and press the "Upgrade via USB" button.
If you are unable to log in to an already configured Liso, you will need to perform a firmware reset.
Firmware reset
A firmware reset updates the firmware and resets all settings. The Liso will be unconfigured and disconnected from Evoko Home and any booking system. This can be necessary if the Liso is not working properly or if you have lost the ability to log in to the Liso.
The firmware reset is done by creating a bootable USB flash drive and restarting the Liso with the USB drive inserted. For full Firmware reset instructions, please see the article: How do I perform a firmware reset on an Evoko Liso?.
