FHEM (TM) is a GPL'd perl server for house automation. It is used to automate some common tasks in the household like switching lamps / shutters / heating / etc. and to log events like temperature / humidity / power consumption.

## Installation

Install the fhemAUR package.

## Configuration

Since version 5.7, the FHEM package uses a different directory layout for its files:

- `/usr/share/fhem` Perl modules and static content
- `/var/lib/fhem` logs and state files, changing content
- `/etc/fhem.cfg` main configuration file

If you have a legacy configuration, please adjust your paths by putting these lines into `/etc/fhem.cfg`

If you like to edit the configuration from the web frontend, make sure the user `fhem` has write access to `/etc/fhem.cfg`.

    /etc/fhem.cfg

    attr global logfile /var/lib/fhem/fhem-%Y-%m.log
    attr global modpath /usr/share/fhem
    attr global statefile /var/lib/fhem/fhem.save

    [...]

    define Logfile FileLog /var/lib/fhem/fhem-%Y-%m.log fakelog

    define autocreate autocreate
    attr autocreate filelog /var/lib/fhem/%NAME-%Y.log

    define eventTypes eventTypes /var/lib/fhem/eventTypes.txt

Please visit the FHEM reference documentation for further information.

## Startup

Just start/enable `fhem.service`.
