Whisperer is an independent product which does not require the Sprite controller to collect data. You can add as many sensors as possible in your Netro app. You can use this solar-powered sensor to monitor your plants remotely, even if you don’t have a sprinkler system. When the water, temperature or light levels of your plants need special attention, the Netro App will alert you.
As each zone is unique, with different plants, sunlight and soil conditions, we recommend to place one sensor in each zone for best watering results. Consider adding sensors for the zones that you care most. However, in a future version of the app, we will allow one sensor to monitor up to 3 zones but the user needs to make sure the zones have similar environmental conditions.

Wi-Fi Connection

Whisperer needs Wi-Fi to connect to the internet. There are two frequency bands used for Wi-Fi communication: 2.4GHz and 5GHz. Most modern routers can broadcast on both bands. Whisperer only uses the 2.4GHz band because the 2.4GHz has a farther range than the 5GHz. To make sure Whisperer is within your Wi-Fi network’s range, the easiest way is to use your phone to test. If your phone is able to detect the WiFi signal, Whisperer should be able to connect at the same location.

Cloud Services

Yes. All the data will be saved on the Netro cloud server. You can view the data and receive alerts as long as you have access to the internet, no matter where you are.

Sensor Data

Whisperer is able to store 64 data samples. It will keep all the data until it has access to the internet and upload the data to the cloud server. You will be able to change the frequency that it uploads, from once every hour to once every 12 hours.

Functionally a very good product. However there are 2 issues I have repeatedly found. The first is that recharging it after a winter shutdown takes about 4-5 weeks of continuous light. The second issue is that despite improvements in the probe, it is still way to delicate for something you push into the ground. I have broken two probes (both version 1) to date.

Nice design and works as advertised. The data seems to be quite accurate and the solar panel is why I buy it. My only complain is the moisture probe which does not seems to be very strong and you need to be careful when inserting it into the ground.

Good concept but poor quality. After 1 week the button collapsed and water damaged occurred, the LED light doesn't stay on (if ever) for more than few minutes, also I broke two of them just pulling them out from the soil, the probe is too delicate. Also too expensive for a worth of maybe $15 of components.

Having the Whisperer sensors for more than a year now and they have been working well. I can monitor the soil moisture level of my garden and that is very convenient. The team recently improved the app to allow adjusting watering for 3 zones out of each sensor which is fantastic as all my zones are now covered!
