@cdce8p, I have some news!
After reinstall Home Assistant about 15 times… Sometimes RPI1 with Hassos, other times RPI2 with Hassos, other times RPI1 with Hassbian, and etc. I try every combination 2 times at least.
But never works…
After this marathon, I tryed to factory reset my router, and tryed some RPIs and OS, but never works too!
But the strange was I had Home Assistant working on my RPI3 (with raspbian) some months ago…
Then I had a idea: My RPI3 used wireless connection. But all new tests I used wired connection on RPI1 and RPI2… And I remember other people with same problem used wired connection on RPI too.
After some new tests, I have good news.
CONCLUSION: If iOS device has wifi connection and RPI used wired connection, the Home app didnt see the Homekit component on Home Assistant. I tryed some configuration on my router, because, probably, the router dont permits multicast between wired and wireless connection!!!
SOLUTION: You may put RPI on same wireless connection, or may configure your router.
Footnote: Now I have a RPI2 with Hassbian, and homekit is working.
Thanks for the help, @cdce8p!
