YoLink Smart Wireless Temperature & Humidity Sensor, Wide Temp Range (-22 to 158 Degree) for Freezer, Fridge, Green House, Pet Cage, Smartphone Alerts - Hub Required

I have lots of yolink devices these are great but I have a cheap phone so had to copy and make code darker and bigger. Then scans fine. Work great with their hub. Fairly cheap. And the product support from the company is one of the best. Plus I like that they are local in Irvine CA.

Ive had 4 moisture sensors in the attic now for over 2 years and 2 temp-humidity sensors. Due to house layout, I have 2 hubs. From day 1 the hubs would not connect to the WiFi. Fortunately I have two router satellite stations with RJ45 plugs. YoLink sent me a third hub over a year ago, but it failed to connect via WiFi as the original two did. Today I pulled the third hub out again (Dec 2022), just to see if something might have changed. No joy, so hub 3 goes back into storage. I continue to see hub connection issues on the Q&A which YoLink attributes to firewalls, user connections, etc. In other words, the problem is with the user. Im convinced the problem is with the YoLink design, which theyve been unable or unwilling to fix. Yes, Ive been in touch with tech support when I originally received the hubs. No joy. Other than the hub issue, the sensors work great, and actually detected an AC condensation leak earlier this year and sent me alarm notices. But dont plan on the hubs being connected to your house WiFi. Maybe they will, but if they wont like many of us, you will have to rely on hard cable connection for operations.

I bought a temperature sensor/alarm just to see if this thing works. Now I have about a dozen devices and they are so easy to install and configure. Ive called support a few times and the support was quick to respond. I have a temperature sensor in a metal building 400 away and it works perfectly. Easy to recommend this product.

The YoLink temp sensors are great. They work well, are accurate and are super easy to install.

Easy wifi setup with hub. Add more in seconds. Very durable and accurate. I use these to monitor my freezers, fridge, and basement humidity. Will buy more as needed.

Perfect so far. Already has save a freezer with 1/2 a side of beef. Door was left slightly open. Alerts on my phone went off late in the night. Saved!

Impressed. I tried 4 types of wireless monitors in my commercial freezer and fridge. This one works. It picks up a signal without ethernet or plug/power line needed. Its lightweight and has a display on monitor. Smart app, no monthly subscription and I can pull up on pc using Bluejeans app. It also has other monitors that can be added - power failure, smoke, Motion detectors Love it

works great amazing range

Ive got these temperature sensors scattered about. There are a couple places I worry about freezing in the winter, and its great to have a sensor in my greenhouse. The alarm went off the other day: it was 95 deg out and the temp in the greenhouse reached 105. Got a notification on my phone and went and opened a skylight. Nice to know I have those sensors watching over things! Also interesting to track humidity in my basement, particularly now that Ive added a dehumidifier. The whole system (hub, etc) works great -- really happy with it.

I confused two products that I bought. Check my Govee review for this YoLink item. I blame Amazon for not having the product brand name on the items to review page … and the icon photos are extremely small! Amazon gets a 2 star on that “service”
