Can't pair wall light switch with ZHA

Found the perfect wall light switch: a Wulian WL-ZCSWNPW-S1322-01 (http://www.wuliangroup.com/en/site/productdetail/527) however can’t seem to pair it at all. I’m using a tasmotized Sonoff Zbridge.

Here’s the log.
Although it “joins” the network it always ends in a failure.Anyone have any experience with this product by any chance?
