Maybe you guys can help, I’m pretty new to HA. Been using it for a couple months mainly to monitor solar, temps, batteries, water levels and more on my off grid homestead. About a week ago HA started showing “Unable to connect” on devices. First it was my brother’s phone, then my wife’s phone, now the iPad I have setup for an overview in a central location. It’s running on a Pi5 hardline in to the internet. Crazy part is if I turn the WiFi off on the phones it will work through the remote access. I’ve tried rebooting HA, rebooting the devices, redownloading the apps nothing seems to help.
Is your wifi set up to block client to client connections?
EDIT: never mind. That should not matter as you have:
By which I hope you mean hard wired to your local network.
Is there anything special about your local network?
e.g. Do you use pi-hole or AdGuard?
Are you using VLANs?
When you turn on the Wifi on phones (Do you have enabled calls over wifi on these phones), i that case they probably won’t even try to connect through the “remote-access”, beside that wifi signal 2.4-5.0 will weaken 3G-4G signals
I don’t believe so, I can still access locally on my phone, other iPad and computer.
I updated my post.
Go to the HA app → Settings → Companion App → Your server (top section).
What is the Internal URL set to?
If it is using an mDNS address (like homeassistant.local) then set it to your server’s ip address instead (assuming you have set a static IP for Home Assistant).
Not that I know of, it’s Starlink and it’s been working since like April-May with no issues. I don’t use either of those.
Internal URL is http://192.168.1.205:8123/
Is it set as a static IP for HA?
If not, has this changed?
As far as I know no changes were made other than downloading the latest core update. I did just recall that with the latest update it asked if the app could know when I was home for higher security. I changed that setting to less secure on my wife’s phone and it let her back in.
Ah, ok. See: Connection security level | Home Assistant Companion Docs
Location permission for the App must be set to Always and Precise for “Most Secure”.
And set your local wifi SSID in the app (click the local URL in the app settings to see this).
