desertcart.com: THIRDREALITY Smart Soil Moisture Sensor Gen2 3Pack,Zigbee hub Needed, nhanced Signal Stability,Capacitive Moisture Monitoring,Garden Planting, Compatible with Hubitat,SmartThings,Home Assistant,Homey : Patio, Lawn & Garden

Review: Gen2 has better connectivity but Gen1 has better temperature accuracy - I have both Gen1 and Gen2 of these sensors. The Gen1 are terrible when it comes to connectivity, they don't stay connected unless they are next to the hub. Gen2 are a MAJOR UPGRADE their connection range is significantly better and much more stable. I have 6 Gen2 and none of them have disconnected since I set them up. The 10 Gen1 sensors I have need daily resets on any that are not within 10 feet of the the hub. That being said, the numbers reported by the Gen1 seem more accurate. On a 90° day the Gen1's all reported something around 90° while the Gen2's all reported around 110°. They do have an offset but not that big. The soil moisture numbers all seem about accurate. Since I'm using them to trigger my watering system I just use a threshold number that it needs to be below. They serve my purposes but know they are not perfect, but for the price they are good enough.
Review: Works great with homeassistant - Worked well, seems very accurate and I was able to integrate with home assistant without trouble. I was doing yard work and broke it by stepped on it , need to buy another one. It worked perfectly well before I broke it. Highly recommend if someone looking for a sprinkler automation.

## Features

### ⭐⭐⭐⭐ Connects easily, limited function with SmartLife, won't work w Alexa
*by M***S on March 28, 2026*

I got this soil moisture meter to help me monitor some of my houseplants, especially as I begin to move them from their indoor winter spots to their outdoor spots. The sensor was super easy to connect. I'm using a generic Zigbee hub connected through the SmartLife app. It connected immediately once I pulled the battery tab. As someone else mentioned, I needed to immediately replace the AA battery, as the one that was included was almost dead. Once connected, I explored the interface in SmartLife and was a little disappointed. I noticed that SmartLife is not listed for this device, so I'll cut some slack here, but every other Zigbee device I've used works with it. The issues I'm experiencing are that there is no way to change the temperature reading to F° on the main device page, and the battery status button does not work at all. The temp on the tile in the SmartLife home page shows F°, but not on the device page (see photo). I've gone through every setting available. Not a huge deal, but slightly annoying. A nice feature in the app is the historical readings chart (pictured). I have an Alexa echo device that has a built-in Zigbee bridge, but this device did not work with it. It will connect, but the device page only shows temperature and not humidity/soil moisture so it's effectively useless. The product page claims it works with Echo devices with Zigbee so this is more of an issue for me, and it's the reason I'm giving 4 stars. Otherwise it works. I ran into a little issue with getting low readings, but after some experiments I realized I need to compact the soil around the sensor a bit, especially for loose, chunky soil like I have in my palm plants. I tried the initial calibration method another reviewer suggested, and I'm not sure whether it did anything or not, but I was only able to get 96% as my highest reading when submersed in a glass of water. I did get it to zero when dry.
