Unable to pair Iris SmartPlus 3210-L2 on Z Wave

Despite many tries, the 3210-L2 is always discovered as

nodeId:17
deviceId:7FFFFFFF
manufacturer:7FFFFFFF
deviceType:7FFFFFFF
inClusters:null
outClusters:null

anything I can try?

There's a whole thread somewhere about joining this thing. I didnt have any issues pairing mine, 10 presses for the zwave side after the zigbee side was done.
I would factory reset it then try again.

Device reset, ZigBee size ok, Wave still shows up as

Manufacturer: 7FFFFFFF Product Name: Device Model Number: Unknown Part Number deviceTypeId: 15

nodeId:19
deviceId:7FFFFFFF
manufacturer:7FFFFFFF
deviceType:7FFFFFFF
inClusters:null
outClusters:null

could be a bug in HE? Those 7FFFFFFF do look like as a comm error or something like that
