The Alexa app should be installed by default on your TV, it could as well be in the settings.
I read on Github that it should be possible to switch to different sources but it seems that this feature has been removed? I want to make the guide button on my xbox controller with a webhook start Steam in big mode on the computer and then switch my TV to HDMI 4. But I canât find how to get the TV to switch sources with this app :-/
I donât think that ever worked
Alright, I understand. Thanks for answering 
What about adding new apps to the function âOpen app App nameâ. I downloaded an app called Go to HDMI4 input on my TV. If I could just make Android TV open that app that would almost be the same. Itâs just that the flow card for opening apps doesnât let you run anything but the predefined list of apps.
Maybe adding new apps to that list is as simple as copy and pasting the code for the other apps and changing some stuff (eg. URL/links)? In that case maybe I can just add it myself and compile.
Sorry, but I have to disappoint you there as well. For example: I like to run a slide show using the âTV Photoâ app on my Xiaomi Mi Box S, but I cannot directly start that app. I have to use a flow to navigate to the app and start it.
Perhaps someone can look into the source switching, but this has been a pain for years now 
Iâve almost done it. I just didnât have enough energy to play around with my PC yesterday so I got half way there.
I use advanced flow. When Homey recieve a webhook, Android TV open an app called âGo to HDMI4 inputâ and after 5 seconds a flow card presses the confirm button. You can find the android app on the playstore on your TV. Then you need to add it to Android TV which you can download from Github and install manually afterwards. There are guides for that.
So far I can manually activate the flow and my TV switches source just as I wanted it to. Now I just need to make an Autohotkey script to send that webhook. Then bind button 13 on my xbox gamepad to run that script I got that figured out though by using Joy2Key.
My issue right now is the script. Iâm not a programmer so my script doesnât work, or maybe it does and Iâm just using the wrong URL in the .ahk for the webhook⌠or everything about the webhook is configured wrong because I have no idea how you set it up correctly. All the guides I can find are for sending messages on Discord.
[Edit]
Solved
To change source on the tv just download âGo to HDMI4 inputâ on your tv via the android store (playstore). That one costs, but thereâs a free version called âGo to HDMI1 inputâ Then download this homey app (Android TV) from GitHub on your PC.
Extract the file you downloaded and go to âhomey-android-tv-1.3.4\androidtv-remote\remoteâ. Open the file apps.ts and add the package name of the app you want to add to the droplist on the flow card on your Homey. You can find the package name by going to the app on the playstore via a web browser and looking at the URL. In my case it is âcom.mpiero.android.tvhdmi4â. Add that to the apps.ts file. Then follow the guide to install apps to homey through PowerShell
When you open an app through Homey with Android TV, just let the flow wait a few seconds just so the app on the TV has time to open correctly. Then send a confirm command with Android TV so the app on your tv opens.
This is what it looks like for me
Great work! Seems to me that just adding it to the Android TV app should still be possible
the Android tv app works great with my TCL tv, except when my tv turns off. I think its because my tv doesnât have a standby mode it completely powers off, so the turn on controls donât work, also if I make a flow that uses the android cards in homey I have to have the tv turned on to select the cards.
is there any workaround for this situation
Anyone else having a problem getting Power On to work with Nvidia Shield Pro? Everything else works perfectly 
I have that issue you mentioned early that my TCL TV loose the connection to the app after a day, so I have to repair the connection. Anybody have found a smart fix for this issue?
I just never switch off my Xiaomi Mi Box S
The Shield does not turn offâŚit Sleeps. And the other version of Android TV before this had no problems. This app can turn the Shield OFF but cannot activate the ON for some reason.
I want to share something that helped me a lot.
My TCL TV doesnât have discrete Input source IR commands, nor does it work with any build in Android input selection change. Not having discrete Input and power commands is a issues when you want to fully utilize a smart remote like the Unfolded Circle Remote.
I found a solution with this app and the flow card: âOpen App [App Name] [App link]â
This is what worked with my TV, I only entered the âApp linkâ value with âcontent://android.media.tv/passthrough/com.tcl.tvinput%2F.TvPassThroughService%2FHW15â
For HDMI1 and âcontent://android.media.tv/passthrough/com.tcl.tvinput%2F.TvPassThroughService%2FHW16â for HDMI2⌠17 and 18 are HDMI3 and HDMI4.
Regarding the âunavailableâ device with the android TV. I too experience the issue, I even tried the Alexa trick without any luck. But I have found a solution and also an indication that the issues is not the TVâs but the app itself.
This only applies to newer Philips TVâs (55oled809) but if I connect the TV to homey over Matter, that integration never loses connection to the TV itself, and I am always able to turn the TV on over Matter. So thats my flow now wake the TV with the matter integration and then control it with the Android TV app.
This maybe be something to look further into for a developer, as the Matter int. is not as feature rich as the android TV app.
You are comparing a completely different service (Matter) with how the Android TV app connects with the TV; they run differently on the TV, have different power options and more. The Android TV connection loss is very well known and the topic start also links a list on the Home Assistant integration page what you can do about it, which depends on the make and model of your TV.
I thought the issue stemmed from the TV going into a sleep state where it disables WiâFi/Ethernet. But that must not be the case, since the Matter service is still able to wake up the TV. Could you elaborate on what the root cause of the issues people are experiencing actually is? Is it that the Remote Service isnât allowed to run in the sleep state in some instances, and therefore isnât able to receive commands?
I depends on how the manufacturer has configured the different services that are allowed to run while in low power mode. Looks like Philips made sure that the Matter service is always allowed to run, but the Android TV Remote service isnât.
But, lucky for you, you can probably combine both to have a way to turn the TV on, and to control it with more possibilities once it is turned on 
Hello,
For the past few days, my Android TV has been going offline in Homey continuously every few hours.
I then have to manually restart the Android TV app, after which the Android TV is immediately back online and controllable via Homey.
I have now created a flow to restart the Android TV App every 4 hours, but it still happens regularly that during those 4 hours the Android TV goes offline and I still have to manually restart the app.
I would like to create a flow that can detect when a device becomes offline/unavailable and then restart the app.
Does anyone know if this is possible and are other people experiencing this problem with the Android TV app?
Thanks in advance!
Hello, you can try this app: Device Capabilities | Homey
This app has a "âWHEN device available or unavailable THENâŚâ flow card.
@Rembo038
Your flow will also get these tags available:
@John_William_Brekke
Thanks for the tip!
I just canât figure out how to set it up.
When adding Device Capabilities, I have to select something, but I have no idea what.
Do you know how to set this up?
