No, it will not act like that with the external smarthings hub. You only get simple TV controls such as on/off, volume, and picture mode. I do recommend getting a smarthings hub and start integrating your devices, lights, door/window sensors. It’s fun. I too was waiting for the extender and I just couldn’t hold out any longer.
Currently I have my bedroom 55ks8000 to turn on at 7am each weekday as part of my good morning routine. I leave the directv box powered on. I don’t have a Harmony hub in the bedroom. I have a harmony hub in the family room and theater but haven’t gotten around to adding a third harmony hub yet.
Just now noticed this is in the UK postings… I am in the US.
I have heard of anymote and tried it but didn’t like the fact of using an android phone with IR to control it. What I actually using is some custom code from the below tutorials to control my directv boxes with Alexa directly without a Harmony hub. I use smartthings to turn on/off the tv. My bedroom setup is small and not a lot of devices, directv and an xbox s. My other rooms have benefited from a harmony hub. The below solutions are for Directv and not sure what you use for your provider.
Are you using CoRE or WebCoRE? Those are the programs/smart apps that can send notifications to the tv. If you are, I can point you in the right direction if it is an option there. I am not sure if the integration is the same on the US side due to different laws and regulations.
I’m only using the smartthings mobile app.
I know nothing about core or website sorry
The link I posted showed what the notifications looked like on their tv.
I really need this option but can’t find away to do it. In the UK smartthings pop ups are allowed.
Once you get use to the program (look through the core Wiki and forum section) take a look at this link that was in your link above. It will tell you where the notifications should be in the CoRE porgram and examples of a core pistion. Hopefully it is available over there and not restricted on the TV. The trigger(s) can be anything you have in your ST system.
Once you get the gist of it, it is fairly easy. I started with one piston with all my notifications for the tv. When I switched over to WebCoRE, I placed the notifications throughout other pistions.
Basically create the piston, select a trigger (door sensor x opens), select the TV and input the text you would like to see when the trigger happens.
The hardest part for me for CoRE was figuring out that in the comparison section, the ones with a solid filled in circles are the triggers. Finding where the TV notification is buried in the actions: When true do>Action #1>all the way at the bottom is Control any device, then choose Select Notification Devices. Select devicenotification (items with house like symbol infront are made availalbe by a device handler), select string for the 1st parameter type and finally enter what you want to say on the TV as the value (see image 2 in the forum link above).
Try a simple piston like door x opens turn on z light. Once that is working, switch out the light portion with the tv notification. If that doesn’t work, there may be a difference in the TV hardware or firmware. I haven’t heard if anyone on that side of the pond has it working. Good luck with it.
