Growee

My favorite part is paying $1200 for this and simple commands like doing a flush, you don't know if it got the order to flush pump D, if it will eventually flush, or if it will just blink and mess around and do nothing. There's no action log to see how much it dosed, or when it dosed, or how long the pumps ran. The calibration is a nightmare lottery. I tested many runs of dosing 100-200ml and found the results constantly off by inconsistent amounts. The app hasn't been meaningfully updated in literally years. I was making these same complaints over a year ago. They spend all their revenue on more marketing. Also you won't be able to make their system work with any other grow app or Home Assistant.

While the device operates as designed most of the time, other times it doesn’t. Sometimes the nutrients doser will fall below target EC and one has to turn EC control on/off to get it to function again. Sometimes the nutrients doser will dose when it shouldn’t. Most annoying part is trying to calibrate pH. Their device makes one wait 3 mins to calibrate pH up / down each. Same for nutrients. Then it says it failed to calibrate and one has to start from the beginning. They have mentioned they are going to update the very outdated app, but so far it’s been like 4+ years since the app came out and zero updates or improvements. It’s like they don’t care and they have audacity to say they make improvement all the time. Lol, lies. Again, it works until it doesn’t. And this is the cheapest doser out there. Purchase at your own risk- this stuff is not cheap.
