This is just a ‘pointer’ post.
All the details are in the kquinsland/yet-another-gps-pps-opnsense repo on github.
For the longest time, I had a dedicated raspberry pi with a GPS module acting as the ntp server for my home network. I chose to use a dedicated host for this because my router - at the time - did not have a serial port that I could leverage.
Long story made very short: the amplifier inside my ancient 2.1 desktop speakers died and I couldn’t find anything “off the shelf” that would serve as a suitable replacement and integrate well with Home Assistant.
So if you can’t buy it, you have to build it! And as it turns out, there’s a whole community of audiophiles that have published designs on all the usual places you’d find free designs for makers. Similarly, there’s a few companies that seems to specialize in audio electronics aimed specifically at people that are building their own speaker systems and just want someone else to handle the electronics and software.
