Is it possible to create a single dashboard on the phone app containing multiple devices ?
Which version of Blynk?
Pete.
The new version of Blynk 2
Yes. A default mobile app view is a screen with multiple devices. It’s called Device Tiles. Every device tile represents a single device. You can show up to 3 pins on the tile. In order to see more data you have to click on the tile.
We are working on the way to create aggregated dashboards, where you will be able to control multiple devices from the same view.
You can do that with scene automation already
