(Updating this first post to make it more clear.) Thanks to Peter (below).
Before I upgraded to Homey Pro, I have been an owner for many years of the Telldus Tellstick Net. One of the things that I really appreciated with the Telldus is that it takes into account that the “Dumb” 433Mhz switches are dumb. That is to say, we do not know which state they are in.
I often find myself in a situation where I (In the Homey app) have to press the icon twice for a 433Mhz device since the “Icon” mistakenly believes that the state of the device is the wrong one. That also creates extra radio traffic.
On the Telldus it shows me what it believes the state of the switch to be, but I can also choose to send whichever command I want to the switch regardless of what the Telldus believes the state to be.
So, the issue is not one of information in the interface, but rather one of sending commands quickly.
I include a picture of how it looks in my Telldus application. It would be very convenient to have this both in the overview view, and in the detailed view of each switch. ( Slightly off topic: Also note that it is possible from the overview view to press on a small icon of a dimmable light and swipe to set the light level.)
