You can’t add a second device.
The front screen (tiles) show the devices, and you create a dashboard for each device. Within a device dashboard you can add tabs, but they relate to that device only.
If you want to send data from one device to another, so that it can be viewed in one dashboard, then you either need to do this using Automations, the HTTP(S) API or Node-Red.
I understood your solution with nodered , thats a tedious way to implement though
This is one of the basic feature blynk should think to provide ofc in plus or pro plans but this is basic ui element which makes use of blynk in smart home easy to use
hmm not at all what a consumer would love to do if they bought the device and want to setup rooms
I understand your point that a way to group using automation is available but if I want to turn on a particular light in particular room , blynk 2.0 made it 100x harder to find and do it
In my opinion they should still find way to make money out of legacy app , some form of subscription rather than just leaving it out completely
I want to jump on 2.0 but seems like Its a step backwards
if they had released blynk iot first and legacy later I bet everyone would have thought that legacy is a major upgrade to iot with better ui ux ofc
