I have been using Blynk several years. With the legacy Blynk, I could connect sensors from multiple devices in the same project by selecting a “source” for the display widget. Within one project, I was monitoring multiple Raspberry Pi temperature sensors. With Blynk 2.0, I cannot see a way to view input from multiple devices in the same project. Thank you in advance for any advice.
No, you can’t do that with Blynk IoT.
You should probably read this recent topic fot info on potential work-arounds…
If you would like to use raspberry pi with blynk IOT then I recommend you to try Node-RED.
