Loving Home Assistant for a long time now. But there’s something I have never been able to complete successfully, which is using the app on my Wear OS Smartwatch. Hopefully somebody here can help me.
So, what I did is:
Home Assistant app is installed on the phone and works fine
Install the Home Assistant app on my watch
Launch the Home Assistant app on my watch
It discovers my Home Assistant instance, and I select it
On my phone, it asks me for username, password and TOTP
On the phone, it asks for a device name (I accept the default)
On the phone, I get dropped back into the “Wear device settings” page, where no device is listed. No error message or anything.
Any suggestions what might be going on?
Additional Info:
The Home Assistant app on the phone is working fine.
The Phone is connected to WiFi
The watch is connected to the phone via Bluetooth (WiFi is disabled on the watch)
I’m running the latest versions of the phone and watch apps.
Launch app on watch
Select instance on watch
HA opens on phone (S22)
Auth screen / login on phone
‘Connect To Home Assistant’ screen with watch device name
click continue
‘Wear Device Settings’
Login Wear OS Device
Back to auth screen
Repeat
Watch Wifi is on (whether its actually used is determined by the watch), but connected to phone via bluetooth. If I turn off BT on phone to force a wifi connection the HA watch app just says ‘cannot connect to phone’.
I’m using the Cloudflared add-on, not sure if that is somehow preventing the watch app working???
Same here. I wonder if the HTTPS is the problem. In order to use ESP Home I had to enable HTTPS.
I am using a self signed certificate. If I try to login into the mobile app I get the error regarding the certificate. I imported the certificate into my smartphone and I could login into home assistant.
Maybe the Galaxy Watch 5 has the same problem. It tries to login and an error occurs because of the
self signed certificate? Are you guys using HTTPS?
I was having the same issue. Hopefully, this should help.
According to the WiFi help on my Galaxy 5 Pro, WiFi is disabled when Bluetooth is connected.
Once I disabled Bluetooth, I was able to connect to Home Assistant from my watch.
Once I was connected, I re-enabled Bluetooth, and I was still able to connect.
EDIT: (15 minutes later) I was wrong. Re-enabling Bluetooth breaks the connection. If I need to control anything, I need to disable Bluetooth.
I looked further at my help and see that the watch will start using WiFi when needed. I am guessing there is a bug where the watch isn’t trying to use WiFi - or at least not fast enough.
I think that problem is with DNS servers over Bluetooth connection. If watch connects using Wi-Fi then it works, if it’s connected via Bluetooth and phone is on local network (local DNS forwarding to local IP /https-certificate workaround) then it’s not working. And if I disconnect phone from Wi-Fi and watch is connected to phone via Bluetooth then it’s again working. So it’s only not working when watch is connected to phone using Bluetooth and phone is on local network and using local DNS that forwards to local IP. That got me to suspect on watch is not using correct DNS.
I had this issue but in my case I had configured my reverse proxy to only allow TLS 1.3, but Wear OS 2 does not seem to support TLS 1.3 yet, after relaxing the restriction to TLS 1.2 it works as expected.
I only enabled to tighten 1.2 some what TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256, TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256, TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384, TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384, TLS_ECDHE_ECDSA_WITH_CHACHA20_POLY1305, TLS_ECDHE_RSA_WITH_CHACHA20_POLY1305
Yep, works for me on Galaxy Watch 5 Pro, with and without WIFI. It finds my setup, can connect then it directs me to continue on phone where I can assign my favorites.
I’m using SSL secured with letsencrypt cert, with port forwarding for port 443 to the hass box on my router.
Basically the same issue here. Tried enabling Wi-Fi and still got the same issue, but didn’t disable bluetooth on the watch.
On the Wear device settings page there is an old “Manage device Galaxy Watch5 (…)”, tapping it does nothing.
I try initiating a login, either via “Login Wear OS device” on the phone or opening the watch app and tapping my homeassistant.local instance and continuing on phone. After entering the device name I get a “Could not register watch” toast and end up back on the Wear device settings screen. And the “Manage device …” is the same as before, not the new device name I entered.
