I use around ten different YoLink sensors and all work well. My only complaint is not being able to move and lock into position the associated icons on the app.

App is a little confusing at first but the product so far seems good.

I recently ordered 2 wall switch 2’s to replace the original Yolink wall switches that have gone bad. Out of the 6 original Yolink wall switches I purchased 5 are now dead. 1 bad switch was replaced with a regular non smart type and 2 others were reconfigured to use the Yolink wall plug outlet, which I’ve had much better luck with. This current purchase replaced 2 wall switches that could not be reconfigured. The new switches 2’s are much better built and considerably smaller and hopefully will have a longer lifespan and be more durable. The new switches were very easy to hook up and pair to the hub and the benefit of have 2 additional sub switches (1 & 2) allows for operating many different scenarios within the system. The operation light on the switch is much smaller and less obtrusive than the original Yolink switch as well. So far I’m very pleased with the wall switch 2 and I hope they will last longer than the original Yolink wall switches which all died at around the 2 year mark. Time will tell. I’ll likely be purchasing another wall switch 2 in the near future because I’m guessing the last working original Yolink wall switch will be dead very soon.

Switches are excellent thanks

I've deployed about 20 of these in various sites, all are working fine. Very comforting to know if water is leaking - we had two disasters in the last two years.

Installation and setup were painless. Got to give yolink credit for making it so easy to set up their devices. I own several water detection devices and have been very happy with them. I plan on trying out the motion sensors

Installed three X3 Smart Temperature & Humidity Sensors in two refrigerators and a freezer, one inside the house and two in the garage. Set up couldn't have been easier; open the Yolink app, click the 'add device' button, scan the QR code on the back of the sensor and it's set up, ready to edit the name and room as you see fit and set up alerts for hi/low temperature and humidity. The data reporting in the app works very well, allowing a variety of options to see the data over a selected date/time range, etc.
And, most importantly of course, Yolink's wireless technology works through the metal walls of refrigerators and freezers as claimed.

Great lock, great price and works perfectly :) I had the lock configured and set up before my installer was done putting in the strike plate. The ability to unlock with a fingerprint, FOB, passcode and key make this a fantastic lock. Best value on the market. Do you think I’m a fan of Yolink products? You bet. Hands down, one of the best smart locks I’ve come across.

Perfect For Pool Temp Monitoring! Works great! Easy to set up and just popped it into my pool and voila!

Despite having good results with Yolink’s door monitors and Alexa, there’s no evidence of connections between the Yolink deadbolt and Alexa. The PIN function works well and considering the price it’s a mediocre deal.

So Far very good!

Easy/intuitive setup. Immediately records pool water temps and provides me with more confidence with temps than my former ancient glass pool thermometer. And I don’t even have to leave my workdesk to see if the pool temp is ready for my swim workout. Outstanding technology!

Was using a Yolink thermometer hanging in pool before this. It has worked flawlessly for over three years! Put this in place and expect nothing less. Yolink is great!
