Hi,
I am working on a project to create a solar powered garden gate sensor. There is plenty of examples out there for solar weather stations on running on esp but I am stripping the sensor part and replacing it with magnetic reed sensor.
I think I have got all the parts sorted (just waiting for aliexpress to deliver all the bits) but the one thing that I still need to sort out is the deep sleep matter. I want the device to only wake up when the gate is opened or closed so reading the esphome docs I will have to use ESP32 as they only appear to have the option to use wake up pins. I have a couple of NodeMCU ESP32 boards available so I was thinking about using that (unless someone can suggest something less power hungry)
The magnetic sensor has two wires one connected to GND second one to a GPIO pin ( I picked pin 4 as according to the esphome documentation that is one of the wakeup pins)
My basic config base on what I understand about the deep sleep and wake up pin:
binary_sensor:
- platform: gpio
pin:
number: 4
mode: INPUT_PULLUP
name: "Garden gate open"
device_class: door
deep_sleep:
wakeup_pin: 4
Is that correct?
