esp-12 and current weather @ openweathermap.org
Posted: Wed Jul 15, 2015 6:23 amHello everyone,
I'm working on a code to connect to the openweathermap.org api and display the weather information on a LCD via another arduino board (I wasn't able to make the I2C Bus work for the esp8266).
The code is kinda dirty right now and has a few old things in it, which should not be troubling though. So far it's kind of working. I can connect to the api and collect my data. Then I send it to the Arduino mega and it displays the data/numbers on my lcd. For some reason this is only working for the forecast. I can not make it work for the current weather information.
I hope someone can help me out here, cause I'm running out of ideas.
Working Code so far:
When connecting to http://api.openweathermap.org/data/2.5/ ... id=2947416 it tells me, that it connected but for some reason the whole respond is empty, like there is nothing to be read.
