Humidity Sensor Hue/ EnOcean? Repeater?

Hi,

I have an outside shelter (sort of) where I have to check humidity to control a vent.

Currently I have a Hue Brdige for my lights and Enocean Switches with OpenHab2.

I tested an EnOcean sensor in the shelter but it is not in the range. The Hue Bridge is located on a different place so for this the shelter is in range.

Now what I am looking for is either an EnOcean repeater (I do not mind cable powered) or a humidity senosr running with Hue.

Anyone having some hints?

Thanks a lot!
