Let's walk-through the process of adding a Water Sensor. To begin, make sure you have your Water Sensor and Hub near you, and open your SmartAC.Com app on your smartphone.

1) Navigate to your Account tab and tap '+ Add Hardware'.

2) Once in this tab, tap 'Water Sensor'.

3) When prompted with the 'Quick Check' page, tap 'No' as this only applies to members who intend to add an entirely new hardware kit.

4) Ensure that you are indeed attempting to pair a Water Sensor by checking the back of your sensor and confirming the plate is Blue. If it is, tap 'Yep, it matches.'

Multiple Hubs: If you have multiple Hubs, a screen will prompt you to select a specific Hub to pair your Water Sensor to.

5) To activate your sensor you must pull the plastic separator tab labeled "PULL" on it. This will connect the battery to the device allowing for conductivity, your sensor will then begin blinking blue to show an active status. Tap 'Light Blinked' once you see the light.

🚨 If you have already done so and your sensor is not blinking blue then make sure that the negative side of both of your batteries are inserted facing the spring side of the sensor. 🚨

6) Locate your Hub and confirm the Hub's serial number matches the serial number on your screen. Tap 'Ok, got it' if the numbers match.

7) To proceed with the sensor pairing process, hold down the orange button on your sensor (found under the battery cap) with the orange button on the backside of your Hub until the light blinks blue on the sensor. Select 'Verify Connection' after holding down both orange buttons.

8) You will be redirected to the Verifying Sensor page temporarily.

9) Once your Sensor is verified, select 'next.'

10) After the sensor verification process you will have the ability to name the zone that you will be placing your New Water Sensor.

11) Select 'Complete Sensor Setup' to view your newly added Water Sensor to your Devices' List.

12) To confirm you added a new sensor you can check to see the hyphenated number after the Hub Serial number. In this case, we see - 4, which means this is our 4th device connected to your Hub and you have successfully paired your New Water Sensor.
