YoLink SpeakerHub & Two Temp/Humidity Sensors Starter Kit – Audio Hub Plays Tones/Sounds, Spoken Messages, Text Messages, LoRa-Powered ¼ Mile Range, Compatible with IFTTT, WiFi Required

Yolink is a great sensor ecosystem for the home. These temperature sensors are accurate and fairly inexpensive, so we have 6 around the house. In the freezer, refrigerator, outside on a covered porch, in the garage, and in an outbuilding with a well. The outbuilding is 1/4 mile away, so was impressed with the range of the unit. All work great and are easy to set up. So far the batteries have lasted at least a year, and still show full charge. We also use the water sensors and door sensors from Yolink.

I have used Yolink products after searching for something that had better connectivity. This uses LoRa and it has been working awesome. It is easy to setup and you can use it right away. The range is great. I have used it in my attic and refrigerator with no connectivity issues. I have to play with the speakerhub and see what it can do. I'll update my review after trying that out.

I have the hub downstairs in a comm cabinet and devices inside the fridge and freezer. The hub works reliably to continuously monitor the temps and alert me if they get outside the thresholds I have set on the Android phone app. Very satisfied with all of my YoLink products! Highly Recommended.

I found this to be an easy install. The sensors are working well -- one in a basement deep freeze and one in a garage deep freeze. They both have strong connections to the hub. The app was also easy to use to: a) set up temperature thresholds for alerts and b) how the alerts would be delivered to my phone (via app notifications, SMS, e-mail.) To be able to monitor two freezers of food, $55 is well worth it!!

I have been searching for something like this forever. I live on a lake and my boat engine just needed to be replaced because my block heater stopped working and my engine froze. That's a big expense I don't want to pay again but the dock is too far away for wifi and no other thermometer would reach far enough to warn me. This product is perfect. I have the sensor attached near my engine inside the bilge. The hub emits an alarm and an audio warning in my bedroom at a trigger point I set at 35 degrees. If I am awakened by that, or get an alert on my phone, I can go down to my dock and solve the problem (power failure, heater failure, etc...). I've tested it further than 1/4 mile and it still worked! UPDATE: I recently added their Smart Energy Plug to the system. My idea was that if I lost power in my dock, it would go offline and I would get an alert (which it will do). I hadn't realized that this was far more than a simple power switch. It shows actual power usage from the plug. This allows me to see the actual current used by my battery trickle charger and well as the exact time the boat heater kicks on. As a pretty detailed (anal) guy, I have all the data now at my finger tips so I can protect my boat and know ahead of time if an issue could be happening. I really love these devices and they are so easy to set up and use!

Excellent system, has been more capable than I expected. Still waiting to see how it handles loss of communication from one of the sensors due to battery failure or if it’s bad signal. Replaced my lacrosse mobile alerts for home monitoring including deep freezers, heated garages, utility rooms. Robust alerting options, I pay for the premium service but even basic is fantastic.

Bought the hub and two sensors a few months ago after having a complete refrigerator failure prior during which we lost a lot of food since we did not notice it right away. Had zero problems with the app, zero issues with setting up the sensors, and it has been working without fail since setup. Having the alarms in place gives us more peace of mind and the graphing over time is a nice bonus. Have to buy two more sensors for additional fridge or freezer units yet. An additional bonus function is that we had an Internet outage at the house after a very bad storm and the speaker hub gave us instant notice both that the outage was happening and then when it restored. So it sort-of acts like an "Internet monitor" as well. Very happy with this system.

We couldn’t figure out the instructions and wasted our money.
