Hey @alexshalamov - decreasing entropy sounds like a good way forward. But indeed the lower values in lx are the most "informative", as you say. I understand that the difference between 50 and 150 is significant.
In light of this, why not expose just a few lighting levels (permission-less) and offer the full precision behind permissions after all? Having a step=50 is fine, but: 
- though it "defeats" that particular PoC, the thing is still somewhat there
- it makes the API much less useful than it is apparently supposed to be

Sounds like a tradeoff is a challenge here (assuming we only have the current permission models, as implemented in browsers).
