Can blynk take a decision on it's own and send it to the nodemcu?

Hello. If i have two nodemcus ESP8266, the first one is connected to a nodemcu and BLYNK reads the sensor readings on my phone. Is there is any way to make blynk take a decision and control the second nodemcu based on the readings that it received from the first?
Thank you in advanced.

The best approach is to do that ‘decision making’ in the code running on your NodeMCU. As such, it’s not Blynk that’s doing the decision making, it’s being done in C++ code.

but how can the second nodemcu know the reading from the sensor connected to the first one?

You can use Blynk Bridge code.
