Just purchased one if these and this thing is awesome. Reads and monitors everything with wifi or cloud or both. You can set it up to run an entire system automatically and for about 1/4 to 1/2 the price of bluelab depending on how automated you want it. Auto top offs, auto drian and fills, auto ec and ph balancing. Notifications to your phone for all kinds of different parameters that you can set. It will also graph all the information for up to 3 months. If you want longer records you can download them as a file and save them for later. This company and this product are legit, I have spoke with them numerous times and they have great customer service.
I currently have the system set up in a five gallon bucket with automated pH balancing.
The app works the monitor and the website works the controller (they’re working on putting the controller in the app as well).
This is what the app looks like.
This is the monitor interface from the web.
This is the controller interface from the web
I highly recommend this product for anyone looking to automated the grow!!
