Hi all,
I’m pleased to say that my smart garden system has arrived. The packaging was excellent with everything well protected and labeled. Time to start putting it together. Once I figure out how I can host photos to post here I will add some pics.

Now on to the questions;
- I would like to extend the cables a fair bit. Is there a limit to length of wire between the rpi and the sensors? I would like 3m plus of length to work with.

Thanks,
HS

Hi all,

So I’ve completed up to step five in the manual and so far so good. A couple of points to note:
- Sanding of the 3D printed parts is required. Not much; just enough to “break the edge” to remove the little bit of flash on the corners. After that the legs had a tight resistance fit with the top and are quite secure. I used some emery paper for the sanding.

- Fitting the circuit boards into their individual slots in the top took a little more persuading than I expected. This is my first time working with this material (pla?) and it is brittle. I managed to crack one of the lips around the oled slot. No biggie as it doesn’t affect fit and isn’t noticeable.

- For the boards with the Grove connectors on the bottom (oled and sunlight) I had to connect the cable first then fit them into their slot.

HS,

Extending the cables 3M should work. Worst case you might have to adjust the thresholds a bit.

Extend one sensor and then use testMoistureSensors.py to see if you have any difference.

Appreciate the comments about the 3D prints. Next batch we will adjust those parameters just a bit.
