    • Hands down the BEST soil moisture meters!

I have tried sooooo many different 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 which are very reliable and very accurate but you have to poke the soil in multiple places which damages roots, to expensive ones by Blumat that cost $90 per each 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. You can and should also buy their Wi-Fi Gateway that gives you access to the moisture meter data from anywhere in the world and it comes with graphs that show previous days, weeks, months 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 alert when soil goes below your indicated level which is very very useful. Now when it comes to raised beds and 20+ gallon containers I had 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 GW1100 Wi-Fi Gateway. The WH51L model had just came out 2 weeks ago and is only available on Ecowitt's site, but I was able to buy them 2 weeks prior to them being available for sale and it turns out they're. 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.¹🪴🪴 ... show more

    • Works Great! Reliable and Consistent Data.
Color: WH51B
I have five of these operating around my home. I live in an area with extremely poor soil conditions that subject my slab-on-grade home to extreme foundation movement if I don’t keep soil moisture consistent season to season. During long, hot summers my soil dries out and causes my foundation to shift dramatically. I bought a couple of these sensors in late summer 2019 to gauge long-term trends to determine ideal soil moisture conditions. After a year of gathering data, I found a good range for soil moisture to minimize foundation movement. I purchased three more (and a WN51) to stake along the perimeter of my home to monitor my soil moisture in real time. By getting this data I’m able to determine when I need to run the soaker hose and irrigation system around my home. While my foundation still moves, I’ve noticed a dramatic difference associated with keeping soil moisture levels within 5-7% of their target. I realize this might not be the targeted use of these devices, but I believe their reliability in my application serves a ringing endorsement for others looking to monitor the moisture levels in their planters in real time. The user interface is average. The app, without a full PWS, seems less than functional. I almost prefer the web-version to the app because it only shows me the active data. This, ultimately isn’t too important to me. If I could export daily data as a .csv, I’d like that ability but it’s not a deal breaker as my primary use is observation of long-term trends. For those with privacy concerns, it’s easily addressed by connected the hub to the internet via a secured guest network. If you’re not already running all of your smart devices on their own secured network away from personal devices, I suggest you do so. I’ve got a couple notes for prospective buyers: 1) I think I prefer this model (WH51) over a similar moisture meter (WN51) made by Ecowitt. These seem more granular in their ability to notice subtle differences in moisture and react much faster to changes in moisture levels. 2) Use a good lithium ion battery. At least two of my sensors have functioned for almost a year without needing to change a battery. They’ve operated in temps from 20-110F. 3) Spend 5 minutes calibrating your devices to the type of soil where the meter will be placed. Mine are primarily in Texas black clay and they require some calibrating tweaking from default. Also, in relation to the first point, the WH51 seems to have a much larger range from 0-100% saturation than the WN51. No clue why, but I like the more precise ability to measure incremental changes in moisture. I’ll update my review over time with any additional notes or issues that may arise. ... show more

    • Batteries? Batteries? Who needs no stinkn' batteries?

With a couple of 3D printed parts and cheap solar walkway lights (with LEDs removed/disabled), you can make these solar powered and not have to worry about changing batteries. The wimpy batteries that come in the lights are actually sufficient to keep the minuscule power demands of the moisture sensors happy in the dark. As far as the soil moisture sensors themselves, they work great and the number of steps to install additional sensors is zero. Just power them up and, in a few seconds, they appear in the app (which is pretty good). I have five of these soil moisture sensors (so far). Transmission range is surprisingly good, but not suitable for long distances. The app shows both signal strength and a low battery warning. They also integrate into some home automation systems, like HomeSeer, (though a lot more than zero steps is required to do so). In HomeSeer HS4, as of July, 2022, signal strength isn't shown and battery levels always show 0. But it does report the time of the last change in moisture and data provided by the hub, which can be useful. The app does not show the time of the last soil moisture change. Calibration is pretty simple, as long as you can provide a cup of water to dunk the probe tip into for 100% setting and air to set 0%. They're also pretty rugged, though I wouldn't recommend forcing them into hard soil. Time will tell how long they last and how long those cheapo solar lights continue to provide power. ... show more
