ZHA not seeing / updating sensor values

Not getting updates on window sensor once paired.
ZHA is lovely and seems to recognize my window sensors ( XHS2-SE) easily (and I have three of them) - but once it’s paired I don’t get any updates from them at all.

So if I open a window - nothing changes. I’ve confirmed they work with zigbee2mqtt and that the sensors are working (new batteries)… Any thoughts?
