I would love to have a device integrated with ST that informs me about indoor temperature so that an action is triggered when it is above/bellow a threshold. Other metrics such as humiditity, CO, CO2, dust particles etc. are nice to have but not compulsory.
What matters is accuracy and reliability of the service.
weather tile works for me… there is also an option I added for an outdoor sensor on Honeywell thermostats… but I have not configured and smart apps to read that as it would be a custom capability.
