Looking at the website and the two products, the site its confusing in terms of what they are measuring.
The Weather Station's Indoor Module measures your indoor comfort by providing vital information, alerting you when you need to air out your home to bring down its pollution levels.

Looks like that the additional indoor sensor does less than the indoor sensor when part of the weather station package?
Im trying to decide what to go for: if health coach or weather station as they are pretty much the same price nowAlso is that fair to say that the indoor sensor compare to the health coach is exactly the same in terms of information retrieved from the sensor appart of the app and the advice text?
