1	Open the Elon Smart app. (Download the Elon Smart Water app from the Google Play or Apple app stores if you don’t have it installed on your phone. Make sure that you have the latest version of the app – you can check by searching “Elon Smart Water” in your app store and tapping “Update”.)	🞏
2	If you don’t have the specific thermostat in your device list, scan its QR code (on the house DB or on the thermostat itself) to add it by tapping the + button in the Elon Smart app.	🞏
3	Open the Thermostat Settings screen by tapping the Settings button (the gear icon) to the right of the thermostat on the app status screen.	🞏
4	Check for any alarms at the bottom of the screen and rectify accordingly (See list of alarms at the end of this guide)	🞏
