It has been discovered and i can turn it on and off but i want to know what i need to do in order to create scripts/automations or whatever i need to do to setup buttons on my home assistant dashboard to directly select apps like netflix and use navigation keys up down left right etc.

Of the 1.2% of user using this integration perhaps nobody has tried what you want to accomplish. Perhaps if you showed us what you tried that filed along with any errors others could assist, you need to understand your system anyway and not just copy a solution from others. Like the pinned thread says, This is not a HelpDesk.

I just brought a Broadlink RM4 in the end and stuck it to the back of the TV with the ir blaster facing down. Apart from the direct APP selection everything else worked prefectly. I just used the above code for selecting apps directly.

I looked into pyvizio briefly back when i was looking to do this and couldnt find alot of info on getting it set up. Im pretty new to home assistant as a package and couldnt find any real guide on how pyzivio gets set up. if you could provide alittle info that would be amazing.

I still plan on using the broadlinks as i have 1 on every tv as it gives temp and humidity for the room too which is a nice touch on the dashboard but to have a better integration for the tv would be ideal.

This is what the above code does. All modern Vizio TVs implement a REST API which you can post a JSON payload to it. If you read through the Vizio API docs on Github ( _SmartCast_API), everything is described there.

Then using that AUTH code, I can send commands to the TV just like a remote control but via REST and your home network. As you can see above, it allows you to control Volume, Mute, Cycle input (like pushing the INPUT button), using the D-PAD up/down/left/right and OK buttons, display the Settings or go Back. Everything you need.

I send to it the IP, Port, AUTH code, codeset and code shown in the table above and you have a remote on your screen. I will note that the pyvizio documentation lags behind the Javascript version referenced on that page. I had to read through both to get all of the key commands (codeset and code), especially those for the D-PAD. But you have them above.

I have a VIZIO 42" LED TV, model E422AR, about 3 yrs old (out of warranty). The TV is wall mounted in my bedroom. A few months ago it started randomly 'turning itself off'. By random I mean it might not happen for a few days, then happen several times in the course of a minute. The usual pattern is it happens a few times each evening.

When it happens, there is no picture or sound, the same as if I had manually turned off the TV via the remote, but with one exception: the VIZIO logo on the bezel beneath the screen remains lit, and is 'brighter' than it is normally when the TV is on. Other than the brightly lit logo, the TV appears to be in its normal off/standby state. In fact, if I then press the power button on the remote, the TV turns back on and all is well again (picture and sound) until the next time it decides to randomly turn itself off again.

After doing some hunting around online, I found many other VIZIO customers complaining of similar symptoms, although in most of those cases I the TV either failed completely (wouldn't turn back on), or the user had to unplug the TV, wait 10 or 15 secs, then plug it back in to get the TV working again (I've never had to do that). And no one described their TV's logo as still being lit when the TV failed.

Since most of the failed cases I read about turned out to be a bad power supply board, I went ahead and purchased one online. It was an exact match to mine, right down to the board's manufacturer, part number and rev letter. I went ahead and swapped the boards, powered the TV back on, and within a couple of minutes it failed again with exactly the same symptoms. %#*@.

So at this point I can safely assume that either the problem is *not* the power supply board, or the replacement power supply board I bought online has exactly the same problem as mine (certainly a possibility; I'm sure the board I purchased was used).

I have a hunch that the TV's hardware is ok, that this is some sort of glitch in the firmware. I can imagine there are points in the code where the default action in response to some error condition is to put the TV into the exact same state I'm seeing now. I could test out that theory by reverting back to an earlier firmware level and see if the problem disappears or the symptoms change, but it appears VIZIO offers no way to do that -- not only is there nothing in the TV's menus for loading firmware, but there are no firmware downloads offered on VIZIO's own support site.

The problem of course is that I have no way to capture the TV's state at the instant it fails. So checking voltage levels after unplugging the TV and plugging it back in will likely be futile, unless a component is 'on the edge' or out of spec. I could try operating the TV with its back off and, after it fails, leave it plugged in and measure voltages then, but that would be hard to do as the TV is still in daily use.

Because the TV is still in use, any 'try this, try that' type troubleshooting will be painful, as it would mean pulling the TV off the wall, removing the 10,000 screws from the back, testing whatever new steps are suggested, then, short of coming up with an actual fix, reassembling it and remounting it on the wall. So I'm hoping I can get a bit closer to the source of this problem without having to continually open up the TV.

I was able to locate online a replacement power supply board for my Vizio 42" LED TV (model E422AR). I pulled the back off the TV, removed the old PS board and installed the new one. Everything worked as well as it did before, but the random shutting off problem still occurred. The company I purchased the PS board from were great to work with. They offered me a full refund, or would send me a second board to try, just in case there was something wrong with the one they sent me. I picked option 2 A week later I repeated the process of swapping out my TV's PS board for the new one. Sadly, the problem still occurs.

Here's the thing. I haven't see this problem show up now for almost two months, even though the TV is typically on several hours each day. I don't believe the problem is heat related; there's been plenty of days when the temperature of the room the TV is in topped 80 degrees F. (the vent ports are clean and there's plenty of air flow behind the TV.) I thought this problem might be related to variations in the power line voltage, but my TV is plugged into a UPS (battery), so I doubt that's the cause. I still think this is some sort of firmware bug, but without a way to track firmware updates, there's no way for me to be sure.

Given how frequently this was happening to me before - sometimes several times an hour - it is hard to believe this is simply good luck. I continue to use the TV daily, no less frequently than before.

I too have Vizio with the same problem. XVT553SV purchased in Feb 2011 and has done this randomly from the 1st week I had it. Besides being very limited in what capabilities it has, compared to newer updated models, and a couple of hdmi ports that quit working, it has served me well so far. I have it attached to a APC 1400 UPS for protection. Usually this happens out of the blue with no pattern I can discern once every few weeks to a month and lasts for 5 min. I originally was told by Visio it was updating firmware and of course I drank that cool aid. As it is now going on 6 years old I count it as lucky it still works from what I read and hear from others regarding Vizio televisions so I guess I got my moneys worth at this point.

Ok, so i bought my Vizio d40-d1 one year ago. Dang it. This mind reading weirdo TV shuts off if i get up from chair and move two feet sometimes. This TV is about 14 feet from chair. Laptop nearby. The Vizio is set for no tracking and is not connected to internet. I do sometimes connect laptop to TV via hdmi cord, but not often.

What makes it shut off like that ? No light either. Is something causing that phenomena in anyway related to the router in other room , TV, then laptop, in a line like that. Right, i know it makes no sense but my moving a few feet must disturb something, waves? , in the space around. I was dumb when i bought a smart TV. Miss my old square 700lb bulky TV. O, back in the good 'ol days - yea whatever.

I have the exact problem obviously on other web sites people have said that Visio has sent people the box to update tvs then u send it back to them and it's all fixed! If it's shutting off for awhile like mine did it for about a week then today it went off entirely. It comes on but shuts off tried all the little tricks but nothing but I did notice that as it turns on the logo comes off and it immediately shuts off even tho the Visio light in front stays on but no power light I've noticed. So seeing how I'm in the middle of a blizzard I am going to call Visio tell them what I read on other web site and see what happens keep u posted!

I rolled over the remotes getting out of bed one morning and Vizio smart tv started this off/on crap! Had no idea which remote cuz all 3 were in same pile I rolled over. After googling it I found your post. Took the batteries out of the fire stick remote and boom! Fixed it! Thank you so much for sharing this. Very helpful!

Under Settings you will see CEC Settings. Turn off the CEC Function. This will be the root cause off the problem for many people as one of the connected devices is sending an improper CEC signal and causing the TV to turn off.

I tried that ,i only have speaker and dvd player hooked up.tried turning CEC to disable -it still hapoens unhooked chromecast -still happens ,different plug in entirely different grid in home -still happens... WHAT ELSE CAN WE TRY????

So I took mine to a TV Repair shop and it acted just fine but when I got hit home and hooked it up again it started all over. So next time I took it the guy asked me what I was hooking up to the TV and we found that by replacing the HDMI Cable it worked fine.
