RAINPOINT Smart Digital Soil Moisture Meter Kit

Work great once I sorted through the app and the need for the hub.

Finally a moisture monitoring system that works! I've been looking for a way to monitor the moisture level in my Bonsai trees, outdoor planters, and indoor plants for a long time. I've tried a couple other products on the market and they're no where near as advanced and well thought out as these! Pros - System can monitor more sensors than you'd ever need - Ability to create alarms that send notifications based on humidity and or battery level. - interface is very intuitive. Creating alarms "scenes" is easy. - Wifi device seems to be fine connecting to devices located ~20ft away and through walls. - So far it's proving to be waterproof. - Ability to chart and log historic moisture levels. - Sensors seem to be working in 4" deep pots. - Individual sensors display % Moisture. Cons - Requires a 2.4Ghz wifi connection and will not connect to a SSID that was broadcasting both 2.4 & 5. - Connects to alibababa hosted servers in China. - An absolute bear to setup if you have an advanced firewall running Suricata / Snort! This tripped 3 Snort rules. - The sensors require a Phillips screw driver (included) to access the batteries. - There doesn't appear to be a rubber gasket sealing the battery compartment. - The sensors require ~ 6" of soil to fully seat. - Instructions are near worthless! I could write better instructions in my sleep!

Connected easily to the hub and app and is working great in my outdoor flower pots.

This is the only smart soil meter I can find on the market that has a display screen on the device itself,so I don’t need to use my phone all the time. Connectivity is stable. APP is easy to navigate and quite functional for plant owners. If wanna check remotely and record moisture level data via the app, buy the sensor + hub version and you can add many extra sensors under the same gateway. This is fairly useful if you have multiple plants or hanging plants. Otherwise, the sensor only version is good enough. I grow dozen of perennials and some veggies either indoor or in backyard and always forget which ones I have watered or not. To keep my plants alive and healthy is never easy! THIS SOIL METER DOES HELP A LOT! Now it is so easy to tell if my plants need a drink while I walk by or check on phone when I’m away. The app allow monitoring moisture level changes over time,so I can adjust my watering plans accordingly. Have 5 of this for now, might get more later. The only downside is the probe is not long enough for some large potted plants. Other than that, this is one of the most useful plant care tool I've ever used. It does bring me peace of mind and keep my plants happier.

Ok for the price, but (a) update latency is quite long (minutes) and sensors disagree with each other by roughly 10%.
