REALLY easy to install; great product; exactly as described. High quality.

I didn't know what to expect, but I heard this product was good.It arrived quickly, was REALLY easy to install and connect with the mobile app.Works perfectly.I have 5 installed in my condo and another 4 installed in my country cottage.You can view their functions by house, location, etc.Highly recommended. Try to wait for a sale, since they are kind of pricey, but they are certainly good.

works even without Wi-Fi and electricity

I am delighted with the devices YoLink. Quality materials and good software, low price, fast response from technical support (they answered me at 10 pm in 15 minutes). Sold on Amazon in different configurations. If you are interested, I will send you links. The most important thing is that the liquid sensors control the inlet valve even in the absence of electricity and Wi-Fi. This is a smart home system, it can control up to 128 devices, light bulbs, taps, lamps, sockets and much more.

Fantastic sensor

This is the 6th sensor I buy plus the hub and a couple of plugs . This is a fantastic little device with excellent connection to hub, push notifications that do not fail . I have had to use only one as I had a leak from the sink and was notified on the second .Super easy to install or add .One of the best purchase I had done on Amazon !!
