Apple just released HomePodOS 16.3 alongside iOS and iPadOS 16.3. Most HomePod updates are fairly mundane, with various improvements and optimizations. However, this update turns on a chip that’s been inside the HomePod Mini from day one. That chip can detect the humidity level and temperature of the ambient air for the room it’s assigned to.
With that information, you can then create automations in the Home app to do things like control your HomeKit-connected thermostat or turn a fan that’s connected to a smart plug on or off.
In order to activate the sensor, you’ll need to do two things: First, install HomePodOS 16.3 on your HomePod Mini. Second, you’ll need to install iOS and iPadOS 16.3 on any devices you want to see and use the readings on.
Both processes are simple, with the HomePod update taking the longest. Below I’ll walk you through the steps.
Once your iPhone or iPad is updated, you’ll be able to see the corresponding readings in the Home app. Below are a few screenshots of what the readings look like for the HomePod Mini I have in my office.
Can I turn off the temperature and humidity readings?
As far as I can tell, right now it’s not currently possible to remove the temperature or humidity reading from the Home app without also removing the HomePod Mini from your home.
Thankfully, they aren’t very prominent in the Home app and you can just ignore them.
Does the original HomePod have the same feature?
It does not. Only the HomePod Mini and the second-generation HomePod that Apple just announced has the sensor.
