Regarding using multiple Virtual Pins from multiple micro controllers


I am working on a project where i’m using 10 esp32 controllers to obtain sensor information from 7 sensors per micro controller. Using the RS485 communication protocol.
I want to know the cons of displaying all the sensor data on a single BLYNK project using 70 virtual pins. Assigning the auth token to be the same for all 10 micro controllers.
I would like to know if this is a appropriate method to conduct this or should i use 10 separate projects for each micro controller.
Thank you very much in advance.


You shouldn’t use the same auth code on multiple devices.
Add the 10 devices to your project, with 10 different auth codes. Just remember to select the correct device for each widget before selecting the virtual pin that you’re using.

The added advantage of this approach is that you’ll be notified if one of the devices goes offline.



Hello Pete,

Thank you very much for your response.
I would like to ask if i used the 10 devices on the same auth will there be any freezing issues while transferring data.
Thank you very much in advance.
