Great Vacuum - obvious misses in app

I have the 900 series vacuum and its replacing one 3 versions ago. Its amazing and a game changer.

The app needs work but it most definitely does the job. Two stars deduction for the lack of below. Well documented but needs:

1) Needs battery indicator - amazing this isnt a feature.
2) Push notifications - please add.
3) Make "works with Nest" compatible.
