Hello @chirag884
Thanks for reaching out to our Nest Community about your Nest thermostat. I apologize for all the inconvenience. I'm here to help you with that.
The Nest Leaf feature is primarily associated with newer Nest thermostat models, and the 2nd generation Nest Learning Thermostat might not be fully compatible with it. While it's possible that older models could still display a Leaf under certain conditions, it's not a guaranteed feature.
The primary focus of the 2nd generation Nest Learning Thermostat is energy efficiency through learning your heating and cooling preferences, but the Leaf visual indicator might not be as prominent.
If you're looking for more detailed energy usage information, you can explore other features of the thermostat or the Nest app, such as energy history.
Feel free to post again if you have questions. We're here to help.
Best regards,
Douglas.
