Multy esp32 to the same router

Hello, I will use 18pcs esp32 to control factory lights by PWM
18 pcs esp32 will connect to the same router, ı use blynk server
ı am afraid of the number of (18pcs) esp32
could you have an idea about the matter, if the number will be problem or not

This sounds like a commercial application for the Blynk system, which is totally forbidden for the free version.
If Blynk feel that you are using the system inappropriately then they may disrupt your access to the system without warning - which sounds like it could have significant impact on your factory.

If you already have a commercial subscription to Blynk then this is the wrong place to be asking this type of question. Instead, you should be asking the guys over at

But, to answer your question…
The number of connected devices depends on your router and how your network is configured.
The free (developer) version of Blynk is limited to 20 devices.


thanks a lot for the answer pete
actually it is not commercial, it is for our own factory, ı have just noticed blynk world and excited to do something with it
ı thought when ı bought energy in blynk app, it would be enough to use blynk app and server

The Blynk T’s & C’s…
