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 1970 reviewsI received the YoLink Sprinkler Controller recently to replace a new Rachio Sprinkler Controller that I had for one year. I found the Rachio Sprinkler Controller while highly rated not all that friendly for my application. I wanted a simple Sprinkler Controller that was easier to use & program. So far the YoLink Sprinkler Controller was exactly what I was looking for, easy programing & easy manual operation when needed. I’ve found the YoLink Sprinkler Controller superior to the Rachio Sprinkler Controller in my opinion.
The only knock is the YoLink Sprinkler Controller doesn’t come with a 24V power supply. It’s easy to wire in the power supply that you have or purchase. I think YoLink should offer the option of purchasing a power supply.
Works great. I would lower sensitivity as it picks up random vibrations if more than 75%. Also don’t put two two close because when one goes off they both report. Again a sensitivity thing. Still giving it 5 stars. And if you have an EISY from Universal Devices you can link them to Alexa and their devices. When mine goes off Alexa announces it.
Using these to rotate the distribution of water in a mountain community in the Caribbean. The ability to set a schedule to rotate the water, and see when water is flowing in the individual connections, is really incredible. Only anxiety regards the longevity of the devices, and literally only time will tell.
Like the thermometers a lot! I like the charts and look back on the temperatures. I do wish we could arrange the order of the items we have in favorites!! I feel like the fingerprint reader on the locks is too hard to use. Very finicky on finger position. Over all great products!!
The motorized valve controller works well, however In needed a plumber to install it. I disconnected my wifi network and it still worked like a champ!
When I received my order it was missing one item, I e-mailed YoLink got quick reply and they had the missing item shipped out to me right away. Great service
An awesome device, when travelling it’s a relief to know that if a leak occurs at home, I won’t return to a flooded house. LinkedIn my main water supply valve to multiple leak sensors and to a gardening watering system.. can’t imagine not having them
i'm so happy I bought this 10 pack of the water leak sensor 4. I've had two floods in my house to date and they are nightmare. These little units, in addition to some other sensors I bought from YoLink, are giving me peace of mind that I can catch any water leaks early on and act quickly to stop a flood in the future. Of course I would have to be home to shut off the water or send a neighbor over in an emergency situation but the alerts on these are great as is their sensitivity to moisture so i think i'd have time to react quickly enough even if not at home. As advised in the users manual I simply used a slightly damp paper towel to test each of these units and immediately they detected the moisture. i love that the alerts override do not disturb on my iphone too. although i did realize that if my apple watch has sound shut off i will not hear the alert. so i keep it on now. I also have enjoyed working with this company. I didn't have any issues with this 10-pk of sensors but a different item I purchased had a bit of a defect and they responded right away and did the right thing to correct the problem. I'm very happy with this purchase and the prior one I made which gives me even more coverage for items like my furnace, hot water tank, cold water tank, and Hydro air handler and I'm hoping that I will never have another flood and major damage again because I have these little gems on hand. These particular units are also small and look nice so even when they're in plain sight such as under each of my toilets and under my fridge they are not an eyesore with my decor. They blend very naturally with their plain look. the app is nicely designed too. ive only had them a couple weeks but i hope they will last and keep functioning well for many years. i like that we we'll get a low battery alert too when the batteries diminish. with the exception of the apple watch issue they seem to have covered everything! thanks yolink!
I love Yolink products. This speaker hub is working well and as intended.
The team at YoLink were amazing. I inadvertently ordered the wrong valve control after speaking with customer service. They advise me on what valve control I actually needed and send me the correct one with a shipping label to return the one that I purchased great job everyone keep up the good work.
Working fine
I've had two other water sensor, water valve shut off systems. One went out of business the other was not very good. After reviewing numerous YouTube videos this one looked very good. I like that the system uses it's own proprietary software. The valve controller will run on 4 AA battery backup in case of power outage and the D2D setup will also allow the water sensors to communicate with the water valve controller if WiFi and or power is out. What a great system!! This is the way a water leak sensing system with water valve control SHOULD WORK !!! The talking hub also works flawlessly.
This thermometer works great to monitor refrigerator temperature and receive alarms when things go wrong.
