What it does

• Reads the thermostat’s current temperature, humidity, and heating/cooling state.
• Lets Home Assistant automations and dashboards display and adjust the thermostat.
• Helps estimate heating energy use from thermostat runtime.

What it does not do

• No data is shared with, or sold to, any third party.
• No advertising, analytics, or tracking.
• It is not offered to the public and has no other users.
