So the readings are all over the board. Sometimes 4.5v with magnet sometimes without, sometimes magnet doesn’t affect it at all.
I’m trying to understand this app. It comes to life.
What does the alarm button do?
Your icon is to small to see what your talking about. But I understand the alarm is to let you know if say the amount of fertilizer you are aiming for is not being applied.

I’m blown away by the ino. I am doing some home cooked home automation with the esp32 (reflashing the NSPanel by sonoff with my own MQTT firmware) and even using freeRTOS to run both cores I don’t manage to harness the power that @SK21 has here. I’m sitting here wondering if he’s as home cooked as me or if he’s got an “eddycation”. 
Very home cooked.
