The intent of this project is to find and document more details about APC UPS protocol. It is based on apcupsd manual and many other web sites. Visit https://kirbah.github.io/apc-ups/ site to see documentation. Contribution is welcome.
Be very careful with all commands provided on this site since you may easily ERASE all configuration on your APC UPS and make it completely unusable. Read documentation and think twice before performing any changes.
