BUTTON says OFF

I have 3 buttons on my APP - for ON, OFF and AUTO. Everything works - but the buttons in use all say OFF. How do I either eliminate the text in the middle. The buttons used to have a V number in the middle - that wasn’t very good - now that’s gone but they seem to have fixed values - I’m assuming ON or OFF… which is worse…

Also for heating - as we don’t have up/down controls - I need buttons for UP, DOWN and HOLD. At the very least the centre of these needs to be blank - OR programmable text.

Help.

Interface will be improved bit by bit. There will be icons and editable text options for both states.

Thanks Pavel- any chance of adding a BLANK option while you develop this - ON and OFF are just no good at all… I have up, down, on, off, auto, manual and other uses for buttons… but if I can’t have that yet, blank would be better than off…
