Or, hear me out, we just use our arms and legs to get off the sofa and flip the switch on the wall? Also, the AC thermostat should have some arrows on it, those let you turn the temperature up and down.
Crazy, I know, but it's true! Your AC, lights, microwave and fridge don't need fucking WiFi and internet.
I mean, most of the automation was already there, they've just marketed their IoT crap to death so now everyone thinks it's new because it's on an app. Honeywell, etc. have all made comfort thermostats (I think that's the right term) that could be programmed with an upper and lower temperatures, so you don't even need to switch between cooling/heating. Some even allowed temperature ranges so you're not just running in basic-bitch temp vs. CPH mode. You could also schedule temperatures based on work, school, etc. Basically everything people are using an app to do now, sometimes better, hanging on the wall in your hallway... ignored... for years.
Cookers, etc. can all be put on $5 timers so they're going when you get home.
I don't know, it all just feels lazy to me. Like something straight out of WALL-E. Old man rant over, I'll stop yelling at the clouds now lol
