This tutorial provides a good walk-through of setting up ifttt. The code in the tutorial is C based.
This repository is for posting in a micropython environment, which can be loaded on your hardware by following the instructions here. It was tested using unix (macos) micropython.
To run the program, an API key from ifttt.com needs to be obtained and put in a JSON file (stored in the same directory as main.py) as follows:
event_cfg.json: {"API_key":"your_key", "event_name":"your_name", "sleep_time":21600}
The sleep time parameter is in seconds.
To run, execute: micropython main.py or micropython main.py -h
A dummy routine (values_dummy) allows the code to run on any hardware by using the defaults.
The code doesn't work on an ESP8266 - it runs out of memory when doing the urequest post. This could be resolved by using frozen modules.
For my application, I used an ESP32 and an si7021 to log relative humidity and temperature to a google sheet.
The following modules are required:
- upip install logging
- upip install argparse
To run on an ESP, a configuration file with the wifi parameters needs to be in the root file system. Here is an example:
wifi_info.json: {"SSID": "xx", "password": "yy"}
