@Stichx360 Im not sure if you are still using your Powermax but I have finally done my integration of Powermax with Smartthings. I can now set/unset the alarm via SmartThings, can see the alarm status and even see when the contact sensors/door sensors change state. Its certainly not perfect yet, but wondered if anybody else would be interested in it - if so I will tidy up the code for release. It is based around a WeMos D1 R2 (serves as a direct replacement for the Powerlink inside)
