Expensive but well worth it
Yes, these are expensive. However, when you buy quality, you only cry once. I'm currently using five sensors and a Gateway, and they are amazing. I'm using three in cigar humidors, one in a freezer, and currently the last one is for ambient conditions in the house. They are super simple to set up, and the amount of information they provide is great. The other night I accidentally left a humidor open, and soon I was getting alerts on my phone telling me the humidity was dropping. Cigars saved! I did find that I couldn't get a sensor to connect in the freezer on my newer fridge because it has very thick doors. Their website warns this can be an issue.I love the ability to set temperature and humidity parameters and get notices when a sensor goes outside those parameters. I love the ability to check the records over the last day, week, month, year, etc. If my home loses power while I'm away, I'll not only know that the freezer is getting warm, but I'll know if it gets warm enough for long enough for the food to thaw. I'll also know if someone accidentally leaves the freezer door ajar and can fix it before my food thaws. I'll also know when I need to add water to my cigar humidors. In short, these sensors have the potential to save me a lot of money. I have a friend who owns a cigar shop and uses these and he got an alert one night that his shop humidor humidity was at 80 percent and rising. He alerted an employee who went to the shop and discovered the humidifier was stuck in the ON position. Had he not had the sensor, he would have discovered the next day that his entire inventory of cigars was ruined. Saved him many thousands of dollars.The sensor in my garage freezer is about fifty feet from the Gateway with an exterior door and the freezer door between it and the Gateway. It still connects! UPDATE: Last night someone in my household left the freezer door slightly ajar. I got an alert on my phone and was able to close the door before it stayed open all night and ruined everything in the freezer! That one alert nearly paid for the sensor.My greatest surprise with these was the incredible customer service. I emailed a question about my Gateway and received a reply within 24 hours. The rep was super helpful, and when we concluded that I wouldn't be able to fix my issue, he promptly sent me a new unit-over the weekend and with 2-day delivery! He was responding to my emails on the 4th of July as well as the Saturday and Sunday of the holiday weekend. Incredible. I'm sold on the products and the company.

Flawless so far
I was concerned about my refrigerator maintaining temperature as it seemed to be fluctuating quite a bit. I bought 2 sensors and the hub. The kitchen refrigerator is on the first floor on one side of the house and we have a small refrigerator upstairs at the other end of the house. I place the hub at close to a midpoint and, so far, it's been able to maintain a continuous connection with both sensors. It is REALLY helpful to me to see a plot of temperature vs time as opposed to just randomly checking. So far, the alerts when the temperature exceeds my set point have been flawless. I've only had them a little over a week so it remains to be seen if it stays stable over a longer time period. I'm pleased so far.

Great product
Why did you pick this product vs others?:We have an ice cream business. have an 8x8 Kolpak walk in freezer. Bought these after having multiple fails w/other thermometers. Since we have thousands in inventory, had to step up an buy a better unit. We've been using them 2 weeks. Placed another unit in an Upright freezer in our biz kitchen. Kids were notorious for not closing door. This solved the problem. Alarms begin sounding as soon as they hit your temp thresholds. You have to have the Gateway for them. Bluetooth will not work. (Distance is too far for us, 40' apart) If you are going to use it in two places. You have to buy the Gateway. It also works great. Since the Kolpak has steel walls, you need to mount the gateway on the exterior of the freezer. it picks up both sensors w/no issues. It has detected the upright freezer door open numerous times already. Great product.

Accurate and easy/fun to use
Very nice app that reads the device over Bluetooth and graphs the temperature and humidity. Easy to pinch to zoom to zero in on a reading or to get the big picture.I used three of these to determine where the hot spots were in my house. I had my AC balanced and compared with the tech's thermometer. It was spot on.You can see on the image that things are very balanced now. Great tool!

Didn't come with boxes or instructions this time.
These sensors didn't come in a proper box with instructions like all the others that I have ordered. They just came in a static bag with batteries. A little disappointing so I knocked a star off, but they are working.
