How to set up Local Blynk Server on Windows :

Step 1 :

Download Java SE Development Kit from : https://www.oracle.com/in/java/technologies/javase-jdk16-downloads.html#license-lightbox

Download the server file from : https://osoyoo.com/driver/blynk/blynk-server.jar

Make a Folder for the data files of the server and save the Java server file in that folder.

Step 2 :

Copy the path of the folder where you saved the.

Open Command Prompt or Terminal and type the following command with the your path and press enter.

cd "<server file path>"
Ex : cd "C:\Users\devat\OneDrive\Documents\Blynk Server"

Step 3 :

Now enter the following command initiate the server and create directories.

java -jar <Name of the Server File for Blynk.jar> -dataFolder <Folder name where main files will be stored>

The problem with this is that the server closes as soon as you close the Command Prompt or the Terminal and also you need to write the command every time you boot your Computer.

cd "C:\Users\devat\OneDrive\Documents\Blynk Server"
java -jar blynk-server.jar -dataFolder Server_Data

How to start your server automatically when your Computer boots :

We need to create a Batch Script to start the server just like we did.

Open notepad and type in

@echo off
echo Starting Blynk Server...
echo Your working directory is=C:\Users\devat\OneDrive\Documents\Blynk Server
cd "<server file path>"
java -jar <Name of the Server File for Blynk.jar> -dataFolder <Folder name where main files will be stored> &
IF /I "%ERRORLEVEL%" NEQ "0" (
   ECHO Server failed to started
)
echo Server started successfully.......
|
Ex : Mine looks like :
@echo off
echo Starting Blynk Server...
echo Your working directory is=C:\Users\devat\OneDrive\Documents\Blynk Server
cd "C:\Users\devat\OneDrive\Documents\Blynk Server"
java -jar blynk-server.jar -dataFolder Server_Files &
IF /I "%ERRORLEVEL%" NEQ "0" (
   ECHO Server failed to started
)
echo Server started successfully.....

Click Save As.

Save it where your server directories are and save it as Unkown and then <File_Name>.bat

Now by opening this script your server will start but it will still not be in the background.

To make this file start with Windows, we make a Visual Basic Script(.vbs). Press Win + R to open Run Command and type in shell:startup to open the startup folder. Make a text document and open it on notepad and then type in the following command.

Dim WinScriptHost
Set WinScriptHost = CreateObject("WScript.Shell")
WinScriptHost.Run Chr(34) & "Path to the .bat file" & Chr(34), 0
Set WinScriptHost = Nothing
|
Ex : For
Dim WinScriptHost
Set WinScriptHost = CreateObject("WScript.Shell")
WinScriptHost.Run Chr(34) & "C:\Users\devat\OneDrive\Documents\Blynk Server\Server Start.bat" & Chr(34), 0
Set WinScriptHost = Nothing

Save as <File_Name>.vbs

Now your Server will start as soon as your Windows is booted. Hope it helps :)
