[App] Guest Account Access (read-only app access)

Hey.
I have a tempest and I’m really happy with it, and enjoying the push features.
I’m in a water sport club and we would like that our members could install the app so the could get notifications if they are on the water and lightning would approach or a sudden pressure drop occur.
Therefor the weather app is not optimal since that cannot provide the push messages.
Obviously members should be guests so they cannot access and change master management PW etc.
without the push messages this is not best fit for the club members, and as I see it this is not supported yet?
