Notifications from Koogeek Door Window sensor

I would like to be able to get PushOver notifications to my phone whenever a door is opened. My sensor is a HomeKit compatible Koogeek wireless door window sensor. Would I be able to do that via the HomeKit binding if there’s no Koogeek one? iOS native notifications via the Home App are very limited and although they work I prefer controlling notifications from Paper UI just like I currently do for my Hue motion sensor.

Any ideas, links? Thanks!
