Rachio 3 Not Responding in Homekit (Again)

I have rachio sin November and it was working fine with homekit. Then it requesters firmware update to the 631 and since then no response.

A restarted the device and nothing, now a i deleted it from homekit and can’t add it back, it just stays waiting for the device.

As someone said before I don’t want to delete the device from the rachio app so I won’t lose everything.

Anyone can help?
