The latest iteration of my climate control dashboard on Lenovo 7" tablet.
I managed to create several RM5.1 rules to run my window aircon modes and change the setpoint via IR over Broadlink RM Mini. The setpoint (22 in centre) is just a hub variable controlled by those rules which is blank when the aircon is off. It also has a hidden switch overlayed that toggles Cool Mode/Off. Green is humidity, not fahrenheit btw. I live alone so I simplified the readout to suit my old eyes.
There is also a '2nd page' for status display and switch controls. I have sized the dashboard so that a flick of the finger up or down changes between 'pages'. The lunchtime tile is a variable countdown timer that is activated when I arrive home (conditionally) which also has a hidden switch overlayed to manually toggle on/off.
I have no idea what I'm doing but I just stumble along with a lot of trial and error and help from posts such as this and https://community.hubitat.com/t/the-noobs-in-complete-guide-to-css-for-hubitat/30592 .
