Hello,
Great tuto. What if you load your program, solder it to a sensor, and then realize you need to modify the program. Is there a way to update it?

Small change required for Json to transmit readings.

The {{JsonPayload}} ingredient is (none)

Note that the URL for the Webhooks – Receive a web request with a JSON payload trigger is in a slightly different format than the regular IFTTT Webhook URL (https://maker.ifttt.com/trigger/{event}/with/key/{key} vs https://maker.ifttt.com/trigger/{event}/json/with/key/{key}).

If the URL of your web request does not include /json/ as above, the {{JsonPayload}} ingredient will be empty:

Hello, very nice and detailed tutorial.
I got an ESP32 and would like to do something similar. I only want to write to a database when a GPO input is switched on and off. The code should be a lot simpler then, right?
How would you program that ?
Thanks a lot, Chris

This is a great tutorial. I would like to continue using C++ with my ESP8266 as I want to add this low power mode to an existing C++ program. Do you have or plan a tutorial using C++ rather than Python?

Hi Erik.
If you’ll have a battery powered project, the ESP8266 board we use in this project is the one that consumes less power in deep sleep mode: https://makeradvisor.com/tools/esp8266-12e-esp-12e/
If you want to use full feature development board, I’ll recommend an ESP32. If it comes with an holder for a rechargeable battery, it’s better because it will make the circuitry simpler.
Regards,
Sara

Hi, I’d like to do this project. My weather station will be placed outside a building and hook up to Wifi there. I am thinking it should be battery powered to gain freedom of placement without worrying about power chords from inside the building. The weather station could operate in the same location for a year or even several years (replacing batteries when required). The weather station must use microPython. Based on this information, would you recommend for this project that I purchase a ASP8266 or ASP32 board? And, in the case of ASP32, would you recommend for this project the board that has a battery holder? Any help will be greatly appreciated.
