What to post in r/lowvoltage
What fits the room, and what gets removed.
Works well
- Ask a clear question about a real low voltage problem, like how other techs price a structured cabling job or which tools they carry on a fire alarm install
- Share a practical tip from your own work that saves a technician time or money on a job
- Describe a tool or workflow you built for the trade and ask the community what would make it actually useful in the field
- Answer other people's questions with your own experience before you ever post about your own product
- Start a discussion about a topic the description names, such as fiber, access control, or PLC work, and let technicians do the talking
Avoid
- Posting something with no connection to low voltage work, since the moderator guidance says to keep posts relevant to the trade
- Dropping a link to your product with no explanation, question, or useful context attached
- Treating the community like a free advertising board, because even without published rules the stated expectation is to be helpful to others
- Asking a vague question like how do I get customers, when the guidance favors clear questions the community can actually answer
- Posting the same promotional message repeatedly, which reads as spam in any trade community
- Ignoring the trade context entirely, for example pitching software to a room of fiber and access control techs with no tie to their daily work

What r/lowvoltage Is For
This is a community of low voltage technicians, business owners, and hobbyists. The description says it exists so people can talk about all types of LV work, and it names fiber, CAT, AV, access control, fire, burglar alarm, PLC, IT, and everything else in that world. So the room is working tradespeople and the people who run those crews, plus hobbyists who do this stuff for fun. If your post would make sense to someone who pulls cable or programs panels for a living, it probably fits here.
What To Post
Since there are no published rules, the safest guide is the moderator one-liner itself. Keep your posts relevant to low voltage work and be helpful to others. For a founder, that means show up as someone useful to technicians and business owners first. Ask a clear question about a real problem in the trade, share a tip that saves someone time on a job, or describe something you built and invite people to tell you what is wrong with it. The policy brief puts it plainly. Focus on sharing helpful low voltage tips and asking clear questions.
What To Avoid
There are no published rules to point at, so the honest answer comes from the moderator one-liner. Keep your posts relevant to low voltage work and be helpful to others. That means a post with no connection to the trade is the clearest way to get ignored or removed, and a post that takes from the community without giving anything back is the clearest way to wear out your welcome.
A note from Anthony
This is one of the rare communities with no published rules at all, which sounds like freedom but really means the moderator one-liner is doing all the work. Keep it relevant to low voltage and be helpful, and you will be fine. I would rather post a genuinely useful cabling tip here than any link, because in a rule-free room your behavior is the only rule.

Common questions about r/lowvoltage
Are there any published rules I should read before posting?
No. The community displayed no rules on its public rules page, so there is no published rule text to quote.
Is self promotion allowed?
The rules page is silent on promotion, so treat it as unknown and lead with something useful for technicians rather than a pitch.
Can I share a link to my site or tool?
The rules page says nothing about links, so there is no stated ban, but a link with no helpful context is the riskiest thing you can post here.
What topics count as on topic here?
The description covers fiber, CAT, AV, access control, fire, burglar alarm, PLC, and IT work, so anything tied to those trades fits.
What is the safest kind of first post?
The moderator one-liner says keep posts relevant to low voltage work and be helpful to others, so a clear question or a useful tip is the safest first post.
