Samsung TV showing offline in ST when TV powered off - Google Home

Used to be that I could turn on my Samsung TV using Google Home. I can no longer do this. GH says the TV “isn’t available right now”. I can still turn it off with GH. I’m wondering why I can no longer turn it on. In ST, the TV shows “offline” when it is turned off and I’m guessing this is the culprit. Are there any settings, perhaps on the router side, that I need to modify to get the TV online in ST (even when the TV is turned off) and, therefore, to turn on using GH? The TV is connected via Ethernet and I’m signed into my Samsung account on it.
I know with Alexa the TV has to be on wifi to be able to turn on the TV but my TV has been wired via Ethernet for years and GH has been able to turn it on.

Hey there!

Thanks for reaching out for assistance.

Have you already tried removing the Ethernet cable from the TV and using wifi?

According to this troubleshooting article: https://www.smartthings.com/products/samsung-tvs-voice-control

You would not be able to turn the TV On using an Ethernet cable, it states to use WiFi and to verify the model code of your TV as it varies by model.

I’d try without the Ethernet cable and see if the symptoms persist.

I hope this message finds you well!

Thank you for the response. I’ve tried using wifi instead of ethernet and have the same results. I can turn off the TV but not turn it on.
That said, I’ve had the TV hooked up via Ethernet since I got it four years ago and have always been able to turn it on using Google Home.
Either way, it doesn’t want to turn on even while on wifi. With Alexa, I used to be able to turn it on when on wifi but even Alexa can’t turn it on while on wifi now.

don’t worry, you are not alone…for the past couple of months my samsung tvs are behaving the same way. I also used Google, so something has definitely broken. I can’t even use actiontiles for them anymore either.

Thanks, that actually makes me feel better :smiley:

I have the same issue with the ST app when powered off with the TV remote. I have three Samsung TV’s with two on Ethernet and one Wifi. NONE of them are reachable in the app after they are turned off as I receive an Offline error. After reviewing the link from @SamsungZell of very limited compatible TV’s I see that mine are not listed. :disappointed:

I’ve got a 2019 Q70R, always on WiFi and for about a month or so, the TV is listed as Placeholder in the IDE, sometimes Offline, sometimes Online. There was absolutely no change in the home config, no devices added or removed.

I use Google home as voice control, but I cannot turn it on anymore as it says that the TV is currently unavailable.

Once the TV is on by remote, I can turn it off using Ghome.

But if it stays off longer than ~30 minutes, I cannot turn it back on using voice cmdlets.

Any ideas?

Same issue here with both my TV 2018 and 2019. It was working fine and then required saying commands twice. Then stopped turn on altogether. Once on, I can turn them off with Google Home. The TV always go offline after it turned off.

Same issue, with Wireless setup. I got the SmartThings app, linked to google home. In the ST app it appears as offline, so I think that’s why google says the TV is offline.

I also have Samsung SmartView_Frame app which was just discontinued, but with this app I can connect to the TV! It gives me a message “connection failed”, but the TV turns on.

I cannot link this app to google home so it doesn’t solve my problem. Look forward to a solution to this, it seems like a problem with Samsung app/tv connectivity.
