Mine works for me, I only have one of them, and the rest of my mmWave sensors are Linptec/Moes ES1. I really do not see much difference between the FP1E and the ES1s. I do like the light sensor in the ES1s though.
I'm using this driver:
Mine senses static presence well, it will even get my dog sleeping on the couch about 4m away.
I did have an issue with my sensor a few weeks ago, it slowly degraded until it would not go inactive anymore, I posted about that in the release post above. I got it fixed with a couple full resets, Otherwise, my FP1E has worked pretty well over the last year or so I have had it.
