I am sorry for hearing that. Hope you will fix this soon.
I opened a ticket and got response from Rachio team. By RMA, they sent a new water meter to me and I sent my old water meter back. Unfortunately, I don’t chance to install the new one.
So what is the root cause of it? I still don’t know this happened.
At beginning I noticed my Rachio 3 lost it’s wireless connectivity to water meter. I thought that was firmware or battery issue. Then I noticed the water leak issue in battery room while resolving the connectivity issue.
