Show THERMOSTAT_MODE in device list instead of PRIMARY_CONTROL?

good to learn by doing, he got some feedback, posted a followup, maybe he’ll refine it too.

OP, below is the reference thread I use for 2-3 techniques to view a different default capability on the phone-app device list. Vseven already described one of these techniques. The simulator technique was still working for me, for a temperature+moisture sensor a couple days ago.

Sure would be nice to have the default capability changeable in the standard phone interface. I miss it again, every week or two.
