@chrismills59 0.0.3.Alpha2 is too old, after this, I can see 3 more releases. can you try with the SNAPSHOT version and check this error? Kindly backup everything before moving into latest version.

I achieved something similar using a pair of scripts and using AND / OR conditions on the motion sensors variables. In this moment I cannot retrieve the script to show you an example, let me know if you need it and I'll try to get it to you in the next days.
