In a previous post I talked about 24v presence sensors for Loxone home automation:

Shout out to Malc Crook (https://hackaday.io/mal8837) and Adam (https://hackaday.io/Bobbsta10) who both contacted me to say that the PIR linked to in the original post is no longer the one you get when you order the same item from the same seller.

Fear not, for I have hacked the new one this evening and it’s pretty straight forward.

Filled with hate for the hackaday.io editing UI as I am, I moved posts over to the hackspace site at http://lamm.space/ though it does look like they've at least introduced the ability to save drafts now...

The rest of the post along with images can be found at http://lamm.space/2016/09/10/presence-sensors-revisited/
