The FHEM forum is a place to communicate with mutual respect. We expect every member to interact politely and in a constructive way.

This is the first and most important guideline for all users in our forum. 

It's operated by the FHEM e.V. (Impressum), a registered charity by german law located in Frankfurt, Germany. To help our non-german speaking members to get an overview of the most relevant rules and conventions applying to here, you'll find below some more of them. It's an excerpt aiming to give orientation but does explicitly not claim to be complete neither to be decisive. The german version is the only fully applicable version of this text and you will find at the end of this text. We put also some further readings (in german) below, please consider these also.

Up to now the forum has more than 20.000 registered members. Despite there's merely no occasion to do so, the moderators are empowered to take measures including total ban of users in case of abuse or massive netiquette ( violation.
So avoid insulting, derogative, sexist or racist statements, threats, personal offenses, disputes or discussions without relevance to technical questions, spam or link spam, advertising and businesslike pursuit of commercial interests.

In case moderators are informed about violations, they might decide without any feedback to the informer. Interpretation of our guidelines is at the discretion of the staff. Note: In cases of personal differences, often opening a private conversation via private message might be the more constructive way to get them solved rather than involving moderators, who may think of better options to spend their spare time.

1. Users

The forum itself is not for profit, so most of the users aren't pursuing businesslike interests also. Nevertheless, forum membership is possible for individuals or organizations with a commercial background, but in those cases we expect respective open information to the other members. If you are pursuing "commercial interests" or doubt whether your personal situation might be considered as such, please do not hesitate to ask for more information about how to deal with this, the german guidelines are found here:,60272.0.html.

2. Privacy

A lot of users and FHEM developers consider privacy as a very valuable good. So no wonder FHEM offers cloudless home automation opportunities.
You'll find quite a number of people propagating the principle: If a problem isn't worth to be discussed publicly, it's not worth being discussed at all.
Keeping that in mind, you'll understand them disliking especially private messages.

When posting, remove personal, real-life information such as home addresses, geographical data and phone numbers (especially check list output, but mark redacted modifications).

4. Getting help

General advice is to take a closer look to general instructions like before posting.

First place for getting information on any FHEM specific topic is the commandref. Additional, there are some basic articles in the Wiki also available in English, best reach out to the

Chances for help will be better, if you add links to the sources in the commandref you used. Additionally, the "list" command will show you and your supporters a lot of valuable information. Please include "lists" of every involved device. Also have a look in the logfile and don't hesitate to post relevant parts of it also, including a few lines before and after the ones you yourself might consider to be relevant. For formatting, use the code tag (# button next to the smileys).

Where to post is also a "good" question, especially for our english users. You might either use the "English corner" - a lot of developers have a regular (but often not frequent) view on new posts there - or post directly in the relevant part of the forum. Especially if you encounter problems with a specific module, direct posting in the relevant forum part is recommended - most developers will understand English posts or ask somebody for help in case if not. You'll find the right place issuing a "help <modulename>" in the command field or looking into MAINTAINER.txt.

For extended problem analysis, you might rise the verbose level of relevant devices, in case of Perl warnings and things not easy to localize use stacktrace (attr global stacktrace 1) for an even more extensive logging.

In most cases screenshots will not provide more info than "list", so prefer the latter.

As the forum is intended to help people to help themselves, you also have the option to move your thread to another part of the forum (functionality is located left hand side below first post) and to edit the thread title.
In case your problem is solved it's appreciated if you make a short summary of the solution you found and edit the first post to mark the thread as [solved]. But do not close it. Others may have the opportunity to ask questions or add other feedback you might find valuable in the end.

Kind regards and good luck!
