First of all, setting up the integration was straight forward, I am receiving values and I will start to tinker with it. Many thanks for putting this up!

I am using an SC2.
Question: "Diagnose" information tells me that there is an update available ...

Controller Firmware
Installed Version 2.05.06
Newest Version 3.20.16

Where can I get any updates and how to install them?

Thanks!

A user reported a bug where the firmware update notification for an SC2 controller in the hass_solvis_control integration is incorrectly referencing an SC3 version as the newest available version. The diagnosis information shows the installed firmware version as 2.05.06 and incorrectly lists 3.20.16, which appears to be an SC3 firmware version, as the newest version. The user is seeking clarification on where to obtain updates for the SC2 and how to install them.
