Hi Ram, glad to hear it, and thanks for your kind words about Sesame! We really appreciate the support.
We currently only have lock/unlock Sesame as triggers and actions for IFTTT. However, we do have lock status and battery level for the API, and we are planning to make these features available when we release direct Google Home integration. We're currently working on Amazon Alexa, and Google Home is next!
The batteries we've included with your Sesame are Panasonic CR123A 3V lithium batteries and we recommend these batteries for best results. Two of these batteries are required to run your Sesame, and here is a guide on how to change the batteries.
Hope that helps and let us know if you have any further questions! - CANDY HOUSE
