out of 4 sensor procured two are working fine , one was broken one has an electric leackage and it is draining the battery in just 2 days. this helped a lot in saving money, time and effort for irrigation , after calibration , this helped to see accurately moisture in the soil so we can maintaining a minimum of 40 % humdity needed for trees. ... show more

    • Pain to setup, but works with Home Assistant
Color: WH51B
I had to get a better 433 SDR with antenna, and read up about the best antenna length for the 915 Mhz signal these devices use in North America. But I have these things setup in Home Assistant. My antenna is in a closest in the back of the house, and it can see all the devices in the front yard. No special hub needed and I can add as many devices as I want. ... show more

    • Easy to use
Color: WH51B
Installed a couple sensors in our garden. Let's me know when the veggies are thirsty. Compliments other home automation devices. When it's too dry, I set my wifi waterer for a good watering. Nice product, however you need to have an Ecowitt system for it to work.

    • Great when they work, but can be flaky
Color: WH51B
I bought four of these, but at time of this review, only two of them are still working. The part that inserts into the ground is extremely thin and is prone to breaking. These also stick up, so unless these are in a planter, all it takes is one errant foot or paw to render the entire sensor useless. Plus, since the part inserted into the ground is part of a single PCB that connects to the rest of the device, if it breaks, the whole thing is rendered useless. Additionally, I have had constant issues with the devices losing connection to the base station, and requiring me to trek out and reconnect them to the base station. Kind of annoying. Overall, these are decent but... there's definitely room to improve. ... show more

    • Works well, make sure to put on the waterproof cap hidden under the cardboard
Color: WH51B
This works surprisingly well! I started out with one to test and am up to 7 so far. The moisture reading correspond pretty well to when plants start wilting. It's different for each plant type but is consistent for the same plant, so is great for knowing when to water, especially if you're not around to see the leaves starting to droop. There is a green cap hidden under the cardboard in the box that holds the sensor in place!!! They probably mention it in the instructions, but who needs instructions, you just put the battery in and the sensor automatically shows up in the ecowitt app for your weather station in less than a minute. The green cap goes over the battery compartment to make it waterproof. It's unnecessarily tight, but I guess that's a good thing. ... 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

    • Works great with Home Assistant!
Color: WH51B
I bought a set of these and the hub for monitoring flow beds in the hot Texas sun. They are working so well, I bought 3 more hubs and have a total of 32 WH51's throughout the flower beds and yard. Very easy to setup and connect to Home Assistant and I can see the moisture state of the whole yard and know how effective the sprinklers are performing. ... show more
