Aeotec trisensor humidity is always 1%?

My trisensor works pretty well as motion sensors turning lights on. The temperature report also seems accurate, but the humidity is always showing zero? I have two of them and they both behave the same. Am I using the wrong driver? Or I missed some config? They are mounted high on the wall but I wouldn't think that makes that much of a difference?

Thx,
P.K.

I'm using the same sensor and see the 1% your talking about but i think its the battery percentage not humidity as the trisensor does not report humidity, the 6 sensor that acotec sell does do humidity
