I did download the zip and extract it on my rapsberry Pi3
Unfortunatly I got an error while executing:
-bash: ./WatchPower: cannot execute binary file: Exec format error
The file format is:
WatchPower: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 2.6.32, BuildID[sha1]=c6c7a4376eece00a010bc7d6ca68da58f38c23d4, not stripped
Are you shure that this is the right format for ARN / Debian ?
