What changes
2026-09-01 THERMONOM12 GUI vT545f vT545f Reworked browser remote-control screen for large displays: a clearer channel area with the control mode selectable right there - for several selected channels at once -, and the channel settings as a full-width sheet with a channel pager and transfer-to-group. The remote control now has its own device-settings section that also shows the address to type into the browser.
Update
Firmware is installed on the device over USB or the service menu — the cloud does not transfer firmware.
