New member here. I’m doing a new house build and decided I want to get into home automation. I’m a software engineer in the USA so some of the hardware stuff is new to me and I have to deal with what’s available and “up to code”. After researching a bunch of projects (lighting, blinds, etc) I decided to prioritize some basic network-connected multi-room audio since:
- In doing lighting or anything else I’ll have to deal far more with electricians and building code
- My wife loves having some music playing throughout the day (easy to get her buyoff)
- Low-risk - If it breaks the house as a whole still functions fine
It also seems like one of the best projects where buying retail vs DIY seems FAR more in the favor of DIY. I’ve got the following plan but I am so inexperienced in this I wanted to see if I could get some feedback on it.

Per Room Hardware:
Estimate (10 nodes): $1000 - As long as the speaker wire is pre-wired I can do it all at once or spread this out over time.
A couple specific questions:
- The amp hats power the pi zeros they are connected to. I assume the PSU should work for multiple nodes. Is the PSU safe and suitable to run say… 10 nodes?
- I’m not sure that I can cut cost down any more “per room” on most of the items. The amp is obviously the most expensive thing but I’m not sure I can do any better for a “home run” setup while getting a strong enough signal to the speaker. However, the one thing I do see that would be notable would be the USB OTG -> RJ45 adapter. I’m curious whether there’s a media server that would run the nodes via a USB hub instead. A decent USB hub should be of sufficient speed to stream basic audio and would be cheaper than the $14/room I think but there’s no mention of any of the audio servers (for example, SqueezeBox) that are actually able to communicate via USB.
- I think the longest individual speaker run will be around 50ft. Should the amp/speaker chosen be able to handle that “reasonably” well? I’m not an “audiophile” (I typically use “stock” speakers on any vehicle or device I own, I use a single soundbar on my TV, etc) but I don’t want it to sounds terrible either.
Constructive criticisms? Alternative Ideas?
