Sharing my home-ass with others in read only mode

Hello, before I spend much time (and some money) in hass and hass cloud via nabucasa, I would appreciate some feedback about my project/need :
I’d like to use hass to manage a private building : I imagine that (and it’s actually done) some sensors push some informations to the things network. As an admin I need an app to display and manage those sensors : I choose Hass (but not installed yet). Now I assume that using nabucasa I will get my data from TTN : thanks to documentation this seems ok.
And finally, once everything will be running, I at least need to grant access in an read only mode (using remote UI) to my hass session informations to the other users on their building : is it just reasonable?
Nota : this account could be dedicated to the building and not my home if needed.
