Made an account specially to reply on this one.
Blynk has been great and helped me a lot with my iot projects.
But the function asked here would be one of the best functions imo.
In my particular setup I have multiple (20 ish devices) rgb led lights, all over the house, multiple per room.
these would be grouped in logical “tags” (object/room/floor/inside/outside/all)
In the selector these tags would be, offcourse, visible.
With the buttons, the lights can then be turned off/on, a color can be chosen, a pattern can be started,…
you also could apply the above to automate blinds, sockets, switches,… around the house/building…
Pardon my “brutality” but I don’t understand why you think this has no benefits.
As I see it this has huge benefits and could lure even more people to Blynk
With this function and my first example you could have a Philips hue, but without a bridge.
Now I’m forced to build a bridge. Not checked if it would be possible, but as i have it in my head now it would require a raspberry pi running node-RED and in blynk use the “menu” to give my choice to node-RED.
But this would mean additional hardware, another single point of failure, more coding, more troubleshooting,…
