INKBIRD WiFi Thermometer Hygrometer 3 Pack with 300ft Wireless Sensors & App Alerts | Indoor/Outdoor Temperature Humidity Monitor for Home, Greenhouse, Wine Cellar | 50 Sensor Capacity & Cloud Storage

Great product!To get started, just download the Inkbird app and follow the instructions. Setting up the WiFi hub is super easy - plug it in and it finds local networks, asks you which one to use and the password. That's it! Then, install batteries in one of the temperature/humidity sensors, wait for it to appear in the app, change the name if you want to, then go on to the next one, install batteries, wait for it to show up, etc.The indoor monitor can be set to Channel 1, 2, or 3, or "Channel 8." Channels 1, 2, and 3 show the temperature/humidity from the appropriate sensor; the "8" in Channel "8" can be thought of as meaning "infinite loop," because it loops through the three sensors, showing each one for a few seconds.I left all four sensors (the three outside units and the indoor display module, which also shows the indoor temperature/humidity) side-by-side on a table for several hours. They differed by less than a degree and you can use the app to add an offset to the reported temperature from each sensor. I added or subtracted a fraction of a degree to a couple of the sensors until the all agreed exactly. They have been working great ever since!Now I can keep track of the temperature inside and outside of the house from anywhere! I tried it using cellular data (LTE) and it showed me all three sensors almost instantaneously. Highly recommended!

I've had these sensors set up for about a month now. They are working great. I have one in the main room, one in my aquarium stand and one outside. As far as I can tell they've always been accurate.You don't need the gateway to make the remote sensors work. Setup is super simple. All you have to do is put batteries in and the base station will automagically pick up the sensor and start displaying the temperature/humidity. Same with the wifi gateway. You power the new sensor on and within a minute or so it will show up in the inkbird app where you can name it anything you like.Setup of the app was actually pretty smooth unlike some other "smart" devices I've had in the past. It saw the gateway right away and connected to wifi after entering the password. You can set up hi/low temperature alarms, schedules and integrate with other smart devices to trigger events based on temperature. Pretty slick.I only have a couple of "I wish" points. One is that the app doesn't see the base station so if you want to see your inside temperature you will need another sensor. Another is that the sensors are only IPX4 rated. Meaning that they should be shielded from rain and direct moisture. There are no seals on the battery doors so putting them under an overhang of some sort is a must.Neither of these are deal breakers for me as I can find other places to put them and still be accurate.Overall I'm super happy and would buy again if I needed more sensors.

I needed an accurate thermometer/humidistat for my incubator. After researching and reading many reviews. I decided to go with Inkbird. Last Friday after setting the eggs for lockdown, the unit I had in my incubator indicated a temperature spike well above the range for hatching. Thinking I must have bumped the knob for temperature control, I immediately reduced the thermostat and opened the unit to reduce the temperature. I monitored the incubator for several hours adjusting the control until the Inkbird unit I had registered the appropriate temperature. Only to find out today (hatch day) that all 42 of my specialty eggs are fully developed but dead in the egg as the temp is too low when taken with an external laser thermometer. This was failure of inkbirds thermometer cost me $420 (the value of the chicks in the incubator). Needless to say, I will be returning these and trying a different brand, I am leary of trusting them for their temperature control outlet as well!

Updated (12/18/2023): Things seem to be running well now. So I've updated my review to 4-stars. I'll revisit and upgrade to 5-star if I don't have any inexplicable issues in a few months.Previous review:Distance from sensor to hub unit is less than 30ft. Works fine plotting day and or working back one day at a time, but trying to plot a week or month and it hangs. If I clear the memory it will work again. But give it another couple days and it hangs again.

Currently using 2 of 3 sensors. One is in my well house (stud and siding construction), about 60 feet from the base station, and the other is in my shop (a metal building) about 75 feet from the base station. The one in the well house works just fine. The one in the shop I had to move by the door closest to the the house and base station. The metal building combined with the distance was just too much for the wifi signal to overcome if I located the sensor in the middle of the building. Now getting reliable signals from both sensors. Also get temperature and humidity alarms on your phone, which is helpful. My primary use is to know if the well house is getting below freezing so I can turn on the heater.

These worked well in the beginning, but recently I had to change the batteries and I can’t get one of the sensors to reconnect. I’ve asked for Tech Support twice with no response. The Tech Support appears to be in China only therefore they’re difficult to reach.Update: I finally heard from tech support and was able to get the device reconnected.

Hello! These little things work great. Accurate when comparing with local information for the outside one, and with two thermostat (old still in service as a thermometer on a table) for the inside units. Very pleased, highly recommended.
