In all of the device FAQs, posts with Additions of more devices of the type under discussion are fine. Things that would be of interest to a new person coming to the thread who is attracted by the thread title.
But once we get into questions about the details of an individual installation, it’s usually better to set up a separate thread for that.
For example, the questions about wiring in a specific room would belong in a thread about that specific model, or a thread about one person’s specific project.
The discussion is definitely welcome in the forum, it will just work better in a different thread.
The purpose of this thread
This thread is intended to lay out in general the various device class options for the UK. Along with links to individual discussion threads for people who want to see more details on any one particular device or device class.
It’s just so that people understand they don’t have to just be looking for an all in one switch to replace their existing dumb switch. They can also look at inwall micros or smart bulbs. And there will be different options available if they have a neutral at the switchbox.
After that, examples of specific devices, particularly ones that might solve general problems that many people have, are also helpful.
But the point of an FAQ is that it is a frequently asked question, that is one where many people have the same question, and the answer is intended to be of interest to many people. Not necessarily all, for example, some people will have a neutral at the switchbox and some will not. But everyone starts out with a similar question and then the answer may be “Some homes will have a neutral at the switch box and some will not , and that will affect the Device choices you will have.“
Once the questions start getting highly individualized, the answers become highly individualized, and the conversation will work best in a thread devoted to that project.
So this is not just a “thread about UK lighting.” It is an FAQ about lighting control options for the UK, meaning the various device classes presented at a high level, followed by individual model examples with links to their individual discussion threads.
You can see an example around post 25 where a long discussion of the wiring for a specific project was moved by the moderators to a separate thread. That was after multiple complaints from people that the FAQ had become too hard to follow.
Since this forum allows any individual member to start their own thread, it’s easy to start a new thread to ask for help on a specific project and receive highly individualized responses.
