YoLink Smart Power Fail Alarm, AC Power Outage Alert, LoRa Long-Range Wireless, Remote Monitoring, App Alerts, Text/SMS, Email Alerts, YoLink Hub Required!

I have a pretty extensive YoLink ecosystem of sensors. This was the latest addition. It was very easy to install, just plug it in and hang it on a nail. It connected immediately and has had a solid connection for several weeks now. It performed perfectly in several tests. I can't speak to battery life yet, as batteries in YoLink sensors usually last well over a year.

Does what I need it to do

Great product. ordered another one.

Yo link devices are so easy to use and super reliable. We use it in 3 homes for peace of mind!

The YoLink Smart Power Fail Alarm has been a game-changer for protecting my garage fridge. I had a recurring issue with a GFCI outlet in my garage that frequently tripped, once causing all the food in my fridge to spoil unnoticed. This device solved that problem brilliantly. It's easy to set up, connecting seamlessly to my phone via the YoLink app. Now, if the GFCI trips, I get an instant alert, allowing me to reset it promptly and save my food. The alarm's reliability is impressive, with no false notifications.

A solid product that I'm hoping stands the test of time. I got it for my home security system and also the hub as well. The system was easy to install with clear instructions where I just had to scan codes and a question I did have about the uses was answered super promptly. The tech support was friendly and gave a lot of helpful information about this alarm and the hub and its features in general. The app itself is also quite user friendly.

I set it up on the outlet where my freezer is plugged. It's always a peace on mind having a device that will alarm you in case of a power outage. The alarm is loud enough to wake me, but does not disturb people in other rooms.

Didn't realize I would have to buy a “hub” to utilize all the features . So it does the bare minimum. A little pricey for what I'm able to use.
