A:Answer I can't answer the first question regarding heat. However, this is NOT a smart TV. I hooked up a Roku stick to my TV and it works fine. I get Netflix, Hulu, Disney+, etc. on my TV using this device. I imagine a Firestick, AppleTV, etc. will also work without issue. You just need to keep in mind that the HDMI ports are behind a metal door. I could get my Roku stick to fit without problem, but I couldn't get a WiFi signal once I closed the protective metal door. I purchased a short HDMI cable extender so that I could keep the Roku stick outside the enclosure. There is a USB port on the back of the TV which supplied enough power for my Roku stick. The streaming devices are not made for outdoors, so just be cautious with them. I have my Roku stick tucked under the roof of my pavilion to protect it from the weather.
