Yes, the Grobo Premium and Grobo Solids both rely on a WiFi connection to the internet to work.
Grobo collects and analyses over 7,000 data points every day (that's a lot of math!). We do this to ensure that your plant produces the greatest yields in the shortest amount of time. Most of the algorithms we use to do this run on our servers to analyze and improve your grow.
This connection also allows Grobo to send you emails! This means we can send you notifications when you have to add water or care for your plant.
If your internet goes down, Grobo will try to reconnect to WiFi every few minutes.
