<ul>

This is a collection of functions that can be used module-independant in all your own development<br/>

<pre>
|
|
# !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
|
|
# IMPORTANT: do not insert your own functions inside
|
|
# the file 99_Utils.pm!
|
|
#
|
|
# This file will be overwritten during an FHEM update and all
|
|
# your own inserts will be lost.

# !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
|
|
#
|
|
# To avoid this, we recommend following procedure:
|

#
|
|
# 1. Create your own file 99_myUtils.pm from the template below,
|
|
# e.g. with FHEMWEB, Edit files, Editing 99_Utils.pm, and saving it as
|
|
# 99_myUtils.pm
|
|
# 2. Put this file inside the ./FHEM directory
|
|
# 3. Put your own functions into this new file
