When you receive a new Liso, the firmware version on the device might not be up to date. In some cases, this might cause compatibility issues. Best practice is to upgrade the firmware so it matches the version number of Evoko Home.
There are however a few different ways of doing this. Here, we will explain the differences.
This is by far the easiest way of upgrading 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 Montitoring tab.
If any of these conditions are not met, you can not use remote upgrade. In this case we recommend a USB upgrade instead.
To perform a remote upgrade of all Lisos connected to Evoko Home:
- log into Evoko Home and go to the Monitoring tab.
- Click the "Check for upgrade" button and wait until it's done.
- Click the "Download firmware upgrade" button and wait until it's done.
- Click the "Upgrade all devices" button.
If you need to upgrade only specific Lisos, skip step 4 and instead click on the Liso you would like to upgrade. Then click "Upgrade this device".
If you need a specific firmware version that is different from the latest, or Evoko Home does not have internet access, skip step 2-4 and instead download the firmware file manually from https://download-liso.evoko.se and place it in the liso_files subfolder, located under the Evoko Home install folder. Then click the "Load firmware" button and then "Upgrade all devices".
Performing a firmware upgrade via USB is also very simple.
- Download the Evoko Liso firmware file from https://download-liso.evoko.se
- Copy or move the file to the root of a USB flash drive. The file is a tar.gz archive but should not be uncompressed.
- Insert the USB stick into the USB port on the back of the Liso
- To perform the upgrade:
- If the Liso is unconfigured, press the "Upgrade via USB" button.
- If the Liso is already configured, log into 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.
A firmware reset upgrades 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 in. For full Firmware reset instructions, please see the article How do I perform a firmware reset on an Evoko Liso?.
