does anyone have an easy way to make a samsung smart tv turn on and show a HA dashboard at a specific time?

Hi Gabriel, turning on the tv with an automation would be no issue, but how would you display the ha dashboard on tv? using raspberry or google cast connected to hdmi or what? share specs please.

My HA is running on a rapsperri pi 4 but its not phisically connected to the TV, they are just on the same wifi network. Actually i`m just planning the setup with minimum extra hardware but the pi connected to the HDMI its a good idea

wont work as ha on pi is shell only..

if there is a way to install the same app that people use on tablets it would be nice

i dont know if your tv has a built in media player, that way you could cast a dashboard to the tv i guess.

cast from the pi?

#

my tv has a built in media player

#

there is a web browser on the tv as well i was wondering if i have enough control on the integration to open the web browser, then go to the HA IP and show the dashboard

#

likely no

#

TV api's are notoriously bad with few features

#

casting is typically your only option

#

you'd have to check if your tv has chromecast capabilties, or use a e.g. google tv casting thing to cast to

#

hmm ok. will try this and come back here!

#

so i assume there should be a way to turn on the tv, then go to the chromecast and start casting. i`ll dig into the automation documentation to learn that as well

#

will start by trying to cast manually

#

yes, take a look at either the SmartThings integration or the HACS SamsungTV integration.

If you need more specs on Samsung, you also may try their discord: https://discord.gg/sajh2Ptr

#

You could do the following to try, use the samsung smart tv integration and from there you can >power on tv >select source=internet and set a default start homepage containing your deskboard url on your tv. I really dont think this is a reliable option though, but you might give it a try 😉

This is a cool idea. I'd plan on a dedicated PI though, just for the HDMI->TV, with a kiosk-mode browser showing a HA dashboard. Shipping this requirement to ChatGPT gave me pretty good direction to take things. Casting can be slow and finicky in my experience. Seems easier to just have an always-on input that you switch to. (I do recognize the OP asked for a low-hardware option...)

The second step in that plan is to get the TV to turn on and switch to the correct HDMI input based on an HA command. But looks like that's covered, above.

gonna try the above today, i will update to you guys about the outcome.

#

Also i noticed that you would be better off with the SamsungSmartTV integration instead of SmartThings integration.

#

well i tried, and succeeded with the above, but it's not really responsive and fast at all...

#

So allthough it might work, using a googleTV cast device will work better. and wakes your tv automatically by hdmi
