It’s almost working, it’s exactly like you said, sometimes it doesn’t get all the numbers, and mine is right next to the TV. When I use the switchbot app it does work all the time (so far), so could it be that there a delay is too long or too short, so that it doesn’t get all numbers?
Also I noticed that if the TV is on and i run the Turn on card in a flow the TV turns off (I understand why, it’s a toggle on/off and i can make a check TV on with Better Logic or through a powerplug), just wondering why there are 2 flowcards, or does it work different on other devices (or TV’s)?
And ofcourse thanks for the very very quick add of this feature! 
Been testing a bit more and so far any 1 number channel always works, 99,9% of 2 number channels work, but 3 nummber channels almost always end up with just 2 numbers on the TV, might give you some insights in what might be causing it
