I justed installed the local Blynk-Server on my Raspberry 1b+ and noticed a mistake in the documentation. I used
to download the server. The github link and filename imply that version 0.41.2 is installed but it actually downloaded the SNAPSHOT version 0.41.3. I think the filename/url is misleading.
Additionally the auto-start script failed because of a wrong filename in the autostart command given in the documentation.
The Documentation says
java -jar server-0.41.2.jar -dataFolder /home/pi/Blynk, but it should be
java -jar server-0.41.2-java8.jar -dataFolder /home/pi/Blynk.
