mr merlins home automation solutions

First, I asked for help here in the past in finding a remotely
controllable power strip with 12V input.

This was a cheap option, and it can work from 12V if you add a 150 ohm
1/2w resistor in series:

In the meantime, I have one plugged in my 8 Channel IO 1-wire board and
it's an easy way to control 120V from a 1-wire signal (although
admittedly, in most cases you'd be better off using Insteon).

Anyway, in the DYI home monitoring stuff, I have this if it's of
interest to others (mostly for the reusable code).

1-wire/owfs house monitoring:

I'm also using the 1-wire 8 Channel IO board to do some HVAC work:
