The topic How to help us help you - or How to ask a good question is a good guideline. But help is a two way street.
First and foremost: On the HA home page is Need help? The very first link of that linked page should be something like, New to Home assistant? Start here. That link would have links like 20 things I wished I knew when I started with Home Assistant, The Home Assistant Cookbook - Index and, of course, How to help us help you - or How to ask a good [forum] question Somewhere on that page also should be How to help others … or, how to write a good answer. Knowing how to help actually improves queries of help.
The same questions are going to be asked over and over again. Yes, you’ve answered those questions a bajillion times, but as it is today, the new person doesn’t know that. If the same question is constantly being asked by newbies, the answer should be part of the Start Here page.
Which points out that the Start Here page should have the HELP US IMPROVE OUR DOCUMENTATION footer so that the more experienced person can keep the bajillion+1 time from being asked.
The use of links in help responses is key. It allows the questioner a place to start a search. (When I encounter unknown situations, I usually start with a google search “Home Assistant [insert brief description here]” followed by fine tuning searches. Not all the answers are in the HA forum.
Reminders of basic debugging techniques are sometime appropriate, but not always. (eg. What happens if you remove that line?)
Remember when answering a question, the answer is not just for the questioner, but all seekers of knowledge who happen upon the question. Anecdotal: Questioner wanted to get recommendations for zigbee devices of a certain ilk. Responder ask, “What’s your application? What country are you in?” The responder might be in Zimbabwe and the questioner in Quebec. The responders answer should start with, “In my experience in Zimbabwe …” The next person with this question just may be from Zimbabwe!
If you put RTFM, link it to the part of TFM that needs to be R’d.
Snarky comments are not helpful. In fact, they are a detractor to a good community. I am thankful that this doesn’t happen a lot but it does happen.
The HA forum has a wealth of information but it is open source. As such, it is challenging for all. It’s a struggle for us all
