As long as it’s paired into home internet site I can check anywhere that I happen to be on my iPhone.

We put leak sensors under all our sinks and today the RO filter drain became blocked after making coffee and started dumping the RO discharge under the sink. The alarm allowed us to catch the leak before a drip hit the floor. We did not go so far as to go for auto shutoff but the sensors paid for themselves today in cleanup time saved. Thanks yolink!

The service was very good, I thank you for that .
However, we are looking for the integration with Homeassistant and that is not working properly. we have multiple location s and the integration do not have a reasonable maturity yet.
For the moment I can't recommend the product and I'm looking for an alternative to replace it.

My old refrigerator needed a new compressor start relay (not a true relay but that's what it is called) - simple swap out. Unfortunately, all the replacements are made in China and are known to fail quickly (unlike the original one that lasted 14 years). I used a sensor in the freezer and another in the refrigerator section to alert me to the next failure of the cheap $5 part. Saves having to unload food and risk spoilage. Yes, I keep spare relays on hand. I hope I'm home when the next one fails. Wish all parts were of the quality of YoLink.

These sensors have been so helpful as we navigate wide temperature swings with spread out coops. They just work and the app lets us see history to sleuth out heater issues. Excellent engineering!
