Hi guys!
I have been trying to let somehow others access some of my data in HA. I have made several sensors (temp, wind speed, etc) that are located all around our city and I would like to make some kind of API response that will let others access all of the data I have in my HA.
I have tried several ways and did not succeed, but one of the solutions that worked well was using nodered (http in / http response). The main problem with that was, that I would have to have NR without a username and password or provide it to them. I did not find an easy way of not letting others acces the whole NR 
(like special user for just this).
I came up with one working solution, that is super janky… Feeding all the data to ESPHome device and let them use its API 
It would not grant them access to any other data, but its really bad solution.
Is there anything that would act somehow like API call, but without acces to any other info inside HA? One company from our city asked me, if I could provide the data I collect, so they could import it in their public Grafana, but I did not find any easy solution for that.
Thanks for any suggestions.
