ECOWITTWi-Fi Gateway Weather Station, with Built-in Temperature, Humidity, and Barometric Sensors, IOT Ready, Supports Ecowitt Sensors Developed, USB Power, 915 MHz

I have tried sooooo many moisture meters from really cheap crap with double metal rods that show light intensity, moisture, and soil pH which is always inaccurate, single metal rod by XLUX company and those are reliable and very accurate but you have to poke the soil in multiple places which damages roots, also used the Blumat $90 meter which is way overpriced and it only shows the moisture without any graph 📈 or remote Bluetooth or Wi-Fi capabilities, and bunch of other ones that were always showing wrong readings until someone told me to try these Ecowitt WH51 and WH51L sensors. The WH51 model is great and shows moisture levels from the top 7 inches of soil which is great for all types of pots up to 7 to 10 gallons. The beauty about this Wi-Fi Gateway is that you have access to the data from anywhere in the world and it comes with graphs that show previous readings that you can compare and dial in your watering habits for better performance. You can add up to 8 devices per each GW1100 Wi-Fi Gateway and it comes with an app as well as their website and you can set up alerts to come in through the app as well as get an email when soil goes below your indicated level which is very very useful. Now when it comes to raised beds and 20 gallon containers I have to purchase the WH51L model which comes with a probe attached to 1 meter long cable which allows you to use them in deep pots/beds/containers and they can also be connected to the same Wi-Fi Gateway. Both models are very accurate. The Wi-Fi gateway also has a temperature and humidity and pressure sensor which gives you readings of the room where the sensor is located. I plugged mine in inside my grow room next to my grow tents to monitor the temperature and humidity inside that room to make sure my grow tents are in an optimal environment. I can't say enough good things about Ecowitt. Customer service is very helpful and very responsive. The only thing I did not like is that they are based in China and you can't really call them and the only method of communication is via email but like I said they are very helpful and responsive. If you haven't tried this company yet then don't waste your money on anything else and do yourself a favor get this Wi-Fi gateway along with the moisture meters and anything else you might need because you won't be disappointed. I will surprised that they are so inexpensive and work so great. I mean when comparing to the Blumat meter that cost $90 it's like comparing apples to oranges because for $90 it should be able to do more, at least have remote capability but it doesn't even have that option. In my opinion it's extremely overpriced and these Ecowitt devices without a doubt are blowing away Blumat meters. I hope this helps.

I was surprised by how small the hub is (about the size of a wall usb charger) and the temp/ humidity sensor is about the size of a digital pocket recording device.Setup was somewhat frustrating as I plugged the hub into a usb charger directly into a wall outlet. I tried 5 times to connect with no avail. I then plugged it into a usb cable connected to a usb port on my router and had no trouble at all connecting to the device.I am extremely pleased with the sensors ability to transmit data. My sensor is in an old metal shed about 100ft behind my home. The HUB is in my below grade basement at ceiling level. I do have a couple small basement windows but I was incredibly surprised to see it is still transmitting and receiving through a sheet metal wall, 100ft, and a glass window to my basement.Once setup the data itself is easy to read and interpret on the ecowitt website.I plan on having a multitude of sensors so this product is exactly what I have been searching for.I can set email alerts to tell me if temp, humidity or pressure reach a certain point, if the hub goes offline for a certain amount of time, even if one of my sensors battery gets low.I can monitor and control everything from my phone or computer anywhere that I have internet access.I have multiple chickens coops that I need to monitor no matter where I am. I am very confident this product will fulfill my needs. There are an array of sensors for almost any need and each HUB can transmit up to 8 different sensors.The HUB itself also reads temp and humidity (confused me at first because I kept reading the indoor temp even after my sensor was outside) (the sensor is called CH1) I can change the name of the sensors as well to make it easier to read and organize.I am beyond pleased with this product. The only thing I have a suggestion for is making the app a little bit more intuitive. The website is very good but the app itself opens up to a useless screen for weather underground and if I'm using the ecowitt sensors I wish it would open up to my device list for ecowitt. But that really isn't a big issue to me.I have searched through hundreds of products, this is simple, you can swap out sensors and add or modify things as you need and monitor it all remotely through a WiFi connection. You can also buy the sensors and other proprietary equipment individually which will fit any customers needs exactly as opposed to some other products that bundle a bunch of crap you don't necessarily need or want just so the price can be listed higher.I rely on my livestock for food, and now I can go anywhere and be comfortable knowing that I can monitor their environments and be alerted to dangerous changes in a multitude of categories.Also it's nice not having to walk out to the coop in dead winter just because I'm worried the heater may have gone out, or the light may not have come on etc. If I get worried I flip open my site and get immediate information on all of my coops individually.

I bought this because it seems to be one of the only devices that can be accessed from a computer rather than only a phone app, and even if internet service is interrupted. This tiny device (about 1x2 inches) connects via wifi and serves up a web page on my LAN with the entire interface for setup and viewing. I can view it on my phone, too, of course. I have my own custom-built monitoring software (yes I'm a nerd) and I can still access data simply, through the web page interface, and record data even during network outages or even power outages, since my system is on a UPS.The GW1100 has a built in thermometer, but I also bought the WH31 915MHz wireless thermometer module. Setting up the GW1100 and the WH31 was easy. I do have quite a bit of experience, but the setup process was clear and understandable and worked first try. I registered with ECOWITT during setup but I think that wasn't really necessary.The $20 price tag is VERY reasonable. The WH31 was only $16. I've been trying to get similar $35 Ambient add on thermometers to work with my Ambient weather stations' ObserverIP network interface, but even though the ObserverIP serves up a similar LAN accessible web page it refuses to show additional devices on it's web page and requires going through Ambient or Weather Underground servers.Interestingly, the GW1100 also found my Ambient weather station, and will display all of its data.I hesitated to try this product, as it looked too good to be true. But it was true. It does happen once in a while! It's a pleasure to write a positive review about an excellent product.
