FAQ
What is the wireless range of the FlexFob?
Do I need a hub if I am using the Alexa integration?
Yes. The Alexa integration operates via an internet connection, which is provided to the fob by a YoLink Hub or SpeakerHub. You also want to have a hub so that you can get low-battery alerts, and to perform firmware updates, etc.
Can the FlexFob be used outside?
Yes, the FlexFob is weather-resistant and can be used outdoors.
Are the batteries replaceable?
Yes, the fob uses two standard alkaline AAA batteries. The battery cover is accessible from the back of the fob. After removing the screw (with a small Phillips screwdriver) gently pry off the cover with a slotted screwdriver. Replace the two AA batteries, then snap the cover back on, and reinsert and tighten the screw.

from 864 reviewsWhile we have not had any leaks since I installed the YoLink speaker hub and 14 leak detection devices throughout my 2 story home, it has given me peace of mind knowing that I will catch any leaks before they can cause significant damage. The speaker and devices were very easy to set up, especially with the excellent support provided by the YoLink customer service phone representatives.
Very easy setup, accurate when compared with other devices, very reasonably priced.
Love the entire YoLink platform and interface. It’s professional looking, intuitive, great price, and reliable. Will be adding to it soon.
Temperature & Humidity Sensor, Hub Required!
Great piece of hardware. I swapped a Phynn water valve out and haven’t looked back. The hardware came with all necessary parts and seems to be very solid.
Dommage que ça n’existe pas avec des prises électriques format européen, ce qui rend parfois l’installation un peu plus compliquée.. Livraison au top. Je trouve le détecteur de mouvement un peu faible en détection et austère dans son design. A l’inverse, le thermomètre-hygromètre est beau, sobre, efficace. Le support Yolink est au Top. Manque aussi que l’enregistrement de mobiles en +596 soient autorisés. Et manque aussi des documentations Pdf sur la fiche technique de certains produits.
I have two of these systems, one at our home and one at our cabin each consisting of a speaker hub and three temp/humidity sensors.
Both have worked flawlessly for years and would highly recommend.
Pros: Great range of use even inside a freezer in outside building!
Great battery life and use common AAA batteries.
Easy to read and configure App, not flashy.
AFFORDABLE SYSTEM WITH NO ANNUAL FEES!
These make great gifts. (WiFi required)
Cons: Can be a bit tricky to pair hub to Internet during set-up but stick with it, it will work.
Product works well, easy add on to original system.
The device itself is smaller than I anticipated, but works flawlessly. The device itself is an easy 5-stars. The app is good, but not great.
This little thermometer/hygrometer is attractive and seems to work well. I like that the size is small but still has a nice readable size display. I think that the case is attractive, and though it is made of plastic (expected) it does not look cheap, because of the nice matte finish and solid construction.
I purchased it because I wasn’t sure if my digital AC thermostat was accurate but the two are in agreement, so I’m inclined to believe that the device is accurate.
The Yolink water detection devices plus hub arrived promptly after my order was placed. The installation, even for a stone-age technician like me, went smoothly and easily, thanks to the great help and support of the Yolink telephone support team. I am very happy, and at peace of mind, with my yolink water detection system set up throughout my house.
I recently installed this unit in my home and it is working great. It is able to turn the valve and shut off the water within a few seconds of the leak sensors detecting moisture. I had to fit it in a tight space between my water heater and garage wall, so I had to mount the EVO Valve Operator upside down to make it fit, but it seems to still work fine upside down. It was a challenge to reach in and tighten the hose clamps, but I got it eventually. Definitely make sure you measure your space before buying, and verify that it will fit in both the open and closed position. The X3 controller gave me no issues and just worked immediately.
These work really well like all YoLink products in my experience. These are especially useful in Home Assistant integrations. Small and unobtrusive and mount on the ceiling it’s a magnetic disc included.
The sensor reaches out to my driveway which is several hundred feet long. Mounting braket was simple to screw into a pine tree.
Having YoLing in place avoids high contractor bills for undetected leaks.
