FHEM on Windows
The following description will show you how to install FHEM on Windows on a separate
USB-Drive, without any Windows-registry modifications.
You can use the internal HD for installation too, and you can register fhem as
a service, see below.
Download the latest fhem-X.Y.tar.gz package from http://fhem.de#Download
(currently it is fhem-5.4.tar.gz), and unpack it into a directory where you
have at least 350MB+ free space. I will use F:\tmp for this purpose, after
unpacking the .tar.gz file we will have a new directory F:\tmp\fhem-5.4
Download a Strawberry perl Portable-Edition (this version won't
generate Registry-Entries, and can be installed on USB disks) from
http://strawberryperl.com/releases.html, and extract it into the previously
created directory, in our case F:\tmp\fhem-5.4
My file was called strawberry-perl-126.96.36.199-32bit-portable.zip
Open a command line window (cmd), change to the previous directory, and start
F:> cd \tmp\fhem-5.4
F:\tmp\fhem-5.4> mkdir log
F:\tmp\fhem-5.4> perl\bin\perl fhem.pl fhem.cfg
There is no visible output and the command won't terminate.
You probably have to confirm a Firewall exception (Do not block), as FHEM
opens a Web-Server Port.
Connect to the FHEM Web frontend (FHEMWEB):
Start your browser (Firefox, Chrome or Safari are preferred) and open
You'll see a smiling-house icon on a light-yellow background.
Update FHEM to get access to the latest development version (recommended
but not mandatory):
In the browser window, on the FHEMWEB page, in the command line (upper text
input field, right of the smiling house icon), type in the following 4
commands one-by-one, confirming each one with Enter:
notice confirm update-20130127-001
attr global backup_before_update 0
- the last command will take a while (around a minute), and after finished
it will ask you to "shutdown restart". Ignore this, and just type
shutdown in the FHEMWEB command line.
- Switch to the command line window, and restart FHEM with the last command,
i.e. arrow up and RETURN or type in again:
perl\bin\perl fhem.pl fhem.cfg
Install FHEM as a service (better to install perl on the internal hard-disk
for this scenario):
Terminate fhem by typing shutdown again in the FHEMWEB command line.
Install the missing perl modules by typing in the command window:
Install FHEM as a service
F:\tmp\fhem-5.4> perl\bin\cpan -i Win32::Daemon
F:\tmp\fhem-5.4> perl\bin\cpan -i Win32::Console
F:\tmp\fhem-5.4> perl\bin\perl fhem.pl fhem.cfg -i
