Connecting a smart house over the CAN bus update

Rynius is automating his house using the CAN bus. He hit some issues with noise in the cabling, which he identified and documented the fix.

I had trouble finding wire for the bus and ended up using security cable. Unfortunately it picked up a 60 Hz wave, so I had to add some caps to clean it up.

Cables got noise? Don’t miss Bertho’s mega demonstration of problems with long cables and common solutions.

  1. I’ve been thinking about home automation for quite some time, Still not convinced if wired is the way to go.

    For example, if you want to automate every switch and socket in your home, that requires a LOT of cabling, just for some simple messages. X10 seemed like a good idea back in the day, but apparently has plenty of issues.

    Wireless in itself isn’t perfect either of course, but with low frequency stuff (433Mhz for example) it maybe a better solution.
