There's value in automation across different devices. Just a silly example: I've got a CO₂ monitor in my office. If the level goes above a certain threshold, it triggers a fan and changes the color of an LED light strip to alert me.

Automation is great. What's nice is the thing you described can also be implemented extremely cheaply without any fancy logic or network connectivity, and then it's just a Thing, not an IoT thing.

... Are you really using iot for a co2 sensor of all things? It's one thing if your smart toaster fails to start when your car enters the garage, it's another when a device to save your life decides to do an npm update at the wrong time and you go to sleep. For good.
Sitting in an increasingly concentrated puddle of my own CO₂ when I close the door of my small home office is not a life safety issue. It just seems to affect my cognitive performance at some point. If there were CO₂ tanks or combustion in play, I'd be using a proper industrial CO₂ alarm.
This is probably to keep CO2 below 500/600 ppm, not a safety device.

are you thinking of CO?
CO2 is pretty safe because your body has a built in sensor.
Slightly OT: But what sensor are you using? I've been on the lookout for one for years but always decided they've been too expensive. But now working from home I think it's time to finally get one.
I was looking at this sensor available from Adafruit (and others): https://www.adafruit.com/product/4867
Seems like a reasonable price for a true CO2 sensor.
