## Questions & Answers

**Q: What are the dimensions of the water sensors?  (Inches and centimeters)**
A: The dimension of YoLink Wate Leak Sensor is 2.44*2.44*0.93inches (62*62*23.5mm), the package dimension is 2.48*2.48*1.02inches (63*63*26mm).

**Q: How to make with Alexa? Using a routine?**
A: Yes, use a routine to enable the voice alert from Alexa for YoLink leak sensor. Please refer the video: https://www.youtube.com/watch?v=gr9MpQi2Vwo Thanks!  John from YoSmart Team

**Q: I don't see any rope sensors which is bad for covering areas like washers, fridge, and water heaters.  Any rope solutions I'm unaware of with this?**
A: There are 3 ways to connect the extension cable to YoLink Leak Sensor.
1. Soldering with a soldering iron:
(1) Use a soldering iron to solder 2 common wires (regardless of positive or negative) to a set of probes on the Leak Sensor (a set of probes on the top of the leak sensor is recommended)
(2) Fix the leak sensor in one place (If you use double-sided tape to paste the bottom of the leak sensor to the wall, the thickness of the double-sided tape must be higher than the height of the footpad on the bottom of the leak sensor (>1.5mm), otherwise, the leak sensor may not stick firmly )
(3) Place the 2 wires in the area to be detected. The 2 wires must be separated and fixed with a certain distance (10~15mm)
But please kindly note: If you use a soldering iron to solder the wire, it may damage the two probes of the original device, which may cause the probes to rust in a humid environment.

2. Use glue or tape to fix
(1) Use glue or tape to stick 2 ordinary wires (regardless of positive or negative) to a set of probes on the leak sensor (a set of probes on the top of the leak sensor is recommended)
        a. Stick the wire to the end of the probe and roll it into a circle or ring to expand the contact area & assist in fixing;

        b. It is recommended to use glue/tape with high viscosity, which must be firmly adhered to!
(2) Fix the leak sensor in one place (If you use double-sided tape to paste the bottom of the leak sensor to the wall, the thickness of the double-sided tape must be higher than the height of the footpad on the bottom of the leak sensor (>1.5mm), otherwise, the leak sensor may not stick firmly)
(3) Place the 2 wires in the area to be detected. The 2 wires must be separated and fixed with a certain distance (10~15mm)
But please kindly note: If the glue/adhesive tape fails to stick the wire firmly, it may cause the wire to fall off and the leak sensor may not work properly.
3. Use the Alligator Clip
We have found a way to use the Alligator Clip to clamp securely connecting the probes of the leak sensor and the extension cables, please visit the following video for instruction, https://youtu.be/x-bBXegLUcc 
Please wrap the leak sensor and the clip with tape to prevent it from falling off.
As for the clip, you will find it on Amazon https://www.amazon.com/dp/B0739YWFQ6 
I hope that will be helpful to you.
Any question, please kindly contact us, thanks!

A: Sorry, one email address can be associated with only one YoLink APP account, and one phone number can also be associated with only one YoLink APP account.
