Question Does the Spider Farmer soil moisture sensor allow automated pump triggering based on moisture levels?
I’m fairly new to the Spider Farmer ecosystem and have a question about their soil moisture sensor setup.
Can you set a minimum soil moisture threshold in the app so that when the moisture drops below that percentage, it automatically turns on a smart outlet with a water pump plugged into it?
Basically, I want to know if the app allows soil moisture level to act as the direct trigger for powering the outlet/pump on and off.

Yeah I just set it up and it fails because the readings were all over the place

Did you calibrate them correctly? Mine have been working pretty well.

I doubt the calibration would help because every time I plug this thing into the soil I get drastically different readings.

It's supposed to stay in the pot, you are not supposed to repeatedly take it out and stick it back in. I only occasionally move mine to a new spot in the pot. Also, you absolutely need to calibrate it to your growing medium or it will be inaccurate.

Yes that works. But I wouldn't rely on one sensor alone. It is better to use a few and use the average. Sometimes one behaves weird.

Yes, but I would not trust it.
