I wish roku tv had this. It would help the deaf or light sensitive peoplebthat use any type of light

I wish roku had one the apps with a notice to check tv on iphones so partially or totally deaf people can see the saying to go check tv when bad weather comes. That way we will know when the weather is here. At night I am asleep. Or the could make roku tv come on to alert a sleeping to check the wether apps or channel to see what is up? Thay would be great. And it would probably safe alot lives for either light sensitive and the deaf community. Just a idea and a wish for in the future for all roku tvs.
