Door chain lock detection

This is my feeble attempt at sensing whether I remembered to put my chain lock on. It is ugly and definitely not elegant. Would love any suggestions. I live in an apartment so no permanent modifications and I want it to show closed when chain is on (locked).


That is an excellent idea! I don’t think I ever would have thought of that when I had my apartment

It took me forever to get to this point. If I could change sensor status names it would have been much easier. Just let chain hang down (unlocked) and change name from open to unlocked. I already voted for name change capability.
