If using Arduino IDE 2.x, you can also use Library Manager or drag the unzipped folder into your Arduino/libraries directory and restart the IDE.
Alternatively, unzip the file and copy the folders (often named Blynk , BlynkESP8266_Lib , etc.) into your Arduino libraries folder, typically located in your documents under Arduino/libraries . blynksimpleesp8266 h library zip
Why use the ZIP? Because with Blynk Legacy v0.6.1 (installed manually via ZIP), you can run your own private Blynk server using Docker or Python. This is perfect for industrial IoT where data cannot leave the local network. If using Arduino IDE 2
Look for the latest release (or legacy version). Download Blynk_Release_v0.6.1.zip If using Arduino IDE 2.x
