Compatible with Control-D2D
The fob is compatible with YoLink Control-D2D device-to-device pairing; can directly control compatible YoLink devices, like a YoLink Relay or Smart Plug. The Control-D2D device-to-device pairing feature of the OnOffFob makes it ideal for "offline" or "standalone" applications, where there is no internet connection and/or no YoLink Hub or SpeakerHub (to provide an internet connection for your YoLink devices), as well as for applications where an app is not required or desired, such as for simple applications like the control of a relay or gate operator. For more advanced applications, consider the FlexFob, which can perform the functions of the OnOffFob, and more.
Please note: the OnOffFob can operate without an internet connection and without a YoLink hub, making it ideal for standalone (for example, one siren and one OnOffFob) applications. But, the app will not function for the OnOffFob in these cases, and no low battery level notifications will be sent, the device health (signal level, etc.) can not be checked, and firmware updates (product enhancements, etc.) can not be performed without a connection to YoLink hub and YoLink app account.

Control-D2D Applications
Use the Control-D2D device-to-device pairing feature to pair your fob to one or more controllable devices. Then, you can directly control your device, turning it on or off (activating/deactivating it, unlocking/locking etc.) at any time

Control relays, smart plugs, outlets, switches, and more.

Control your fish tank pump, space heater, humidifiers, etc.

Turn off power-draining devices and equipment when not in use.

FAQ
What is the wireless range of the On/Off Fob?
Are the batteries replaceable?
Yes, the fob uses two standard alkaline AAA batteries. The battery cover is accessible from the back of the fob.

Let customers speak for us
from 1370 reviewsAs said in the title it's easy to setup the YoLink hub and to download the app. I'm very happy to buy this materiel. The signals, however, past through a concrete slab. Nice purchase

Set up is pretty great in terms of ease & quickness. It was confusing to figure out how to get sensors to actually talk to the siren alarm but the agent - Genevieve - was very helpful in walking me thru those 14 steps. Maybe I missed it but it would great to have a visual guide that gives easy instructions on that part.
Thanx so much!

Using it to lock and unlock doors at the office. Works just like it says and was easy to setup and get working.

I have not installed yet but when I do I will send a review

Really gives you peace of mind to know that all fridges and freezers are working in my house and also have the water sensor in all risk areas which is nice

Very pleased with how the sensor works. Even more pleased with your customer service - I can always reach a live person who capably answers my questions.

I have purchased a couple dozen YoLink Water Sensor 2 and Water Sensor 4 units. They all connected to the hub and app immediately, first time, with zero issues. They all work perfectly and they easily connected to a YoLink automated water valve with device-to-device (D2D) pairing. This allows a leak detector to shut off the main water valve with no internet and no hub connection. I've had zero false alarms from the couple dozen sensors I have deployed across 2 homes. I absolutely will buy more YoLink products.

Motion Sensor 3-Pack, YoLink Hub Required!

These things are great. Cover a nice area with the optional 10' extension. Wish I would have bought more of these originally instead of the leak 1 sensors.

Simply great execution. Upgraded from a Honeywell ProSeries that lacked connectivity. Easy wire switch and an incredibly intuitive app made for an easy transition. Now I can turn the heat up just before my arrival even with dynamic travel plans. A great efficiency booster!

Searched everywhere for a solution to the random water pipe leaks costing thousands of dollars in our apartment complex. When coupled with the bulldog valve and detectors, they fit the bill for saving us from large destructive flood events. The speaker hub being able to tell you where the leak is saves searching so you can get straight to the problem. Great pro

Temperature & Humidity Sensor 3-Pack, Hub Required!

Works just like the website and video says it works. no problem:)
