Hello, I setup a small project using my old Raspberry Pi 2B and the Pimoroni GrowHAT. I attached some sketches below. (topdown/sideview) Part list: Raspberry Pi 2B (only ethernet attached/no USB) GrowHAT Mini 3x moisture sensors 3x 1m moisture cable 3x mini pump 3x 1m tube for pumps camera modu…

[image] Tadpole4315: For testing I used 3 different USB-chargers Chargers or Power Supplies? I ask because there is a difference. Have you tried the Official Micro USB Power Supply?

Sadly not the official. The original one I got with the Pi 2B died some time ago. I ordered the official power supply again and will report back when it arrives. I did not think that it would make that much of a difference because it had been running stable for years with a simple samsung USB-cha…

[image] Tadpole4315: So in theory there should be no problem if the power supply is stable? It will help get you a more stable system. Chargers are notorious for not having a stable voltage output under load. And that’s something a Raspberry Pi doesn’t like very much. I would think 2.5A would…

The official power supply arrived today, sadly it is worse than the other chargers I had laying around. I ordered it from one of the official resellers on the official pi website. The water head is at around 0.20m when removing the camera even worse when connecting it. So the problem must be some…

I have a Grow Hat Mini here, setup with a Pi Zero. I’ll blow the dust off of it, and try and do some testing on it, before the day is out. I have errands to run first.

Booted it up discovered that there are no auto watering menu options on this install. I reflashed my SD Card with Legacy 32 bit so I can do a fresh install. It’s doing updates as I type this. I should have something to report before the day is out.

Ok, now I have access to the auto watering pump settings. I’ve turned on the auto watering and near as I can tell it’s all working as advertised. I have one pump that seems noisier than the others, works OK though. No stuttering on any of the pumps. Pi Zero with the latest version of the Official M…

Thank you very much for your testing and time. The problem lies propably with the Pi 2B, I read some other people having problems with this model powering 5V-USB-devices even with the increased power in boot-config. I ordered a Pi Zero2 WH now to run the sensors and pump. If power is enough for t…

A Zero2 is likely a good choice. I found myself waiting quit a bit of the time for things to happen. while I was setting everything up, with just a Pi Zero. It will be more than fast enough for the Grow software. Spoiled by my Pi 4’s and Pi 5 I guess. It’s been a while since I’ve done an OS & softwa…
