I'm also a fan of "hey siri, turn off the tv" when leaving.
I have huge gripes with "what's the weather". Siri will for sure say the temperature, which means nothing in a city where the windchill is often ten degrees lower.
If you have a HomePod and an Apple Watch, you can have Siri turn off all media devices when you leave the house. If you have a CRC receiver for your TV hooked up to an Apple TV, you can have it power down the whole entertainment system when you leave.
