QUESTION
I made a function to clean null values but it doesnt working as well as i expected. This is my change date function.
This function take generated date from thingspeak and change it for better reading.I added option for short version of date and longer.
...ANSWER
Answered 2021-May-29 at 14:03If you look at the Date documentation, you will find that the date parsing will differ depending on the host machine. This explains why it works in codesandbox and not in your machine.
Quoting it:
parses a string representation of a date, and returns the number of milliseconds since January 1, 1970, 00:00:00 UTC or NaN if the string is unrecognized or, in some cases, contains illegal date values (...) There are still many differences in how different hosts parse date strings, therefore date strings should be manually parsed (a library can help if many different formats are to be accommodated).
My recommendation is to use Momentjs to parse and handle the date. It also helps you format your output, so you don't have to do it yourself:
QUESTION
I'm new to API data fetching and I have used this ThingSpeak API library for Android. to get JSON data from a Thingspeak URL to my Java Android application.
The JSON data looks like this
...ANSWER
Answered 2021-May-08 at 07:32Your code represents a JSON Array and not a JSON Object.
getFeeds()
must return a list of Feed
objects. Find the last Feed
object based on the lastEntryId
and which gives you a feedObject
. Now you can print the feedObject.field1
value.
This is a pseudo-code in Kotlin for help.
QUESTION
This was done 2 years ago and was working until today
It used to get data from a JSON on thingspeak and display it to me
I need help to understand what happened and how to fix it
...ANSWER
Answered 2021-Apr-15 at 15:05Run it like this and look at your console. It looks like you might have run your code through a beautifier or something and it altered the line breaks/broke your code.
You'll see that you're having issues with CORS. A good way to resolve this is https://github.com/Rob--W/cors-anywhere/
QUESTION
I have a ESP8266 which can connect to the wifi just fine (can see it on the mobile hotspot) but it does not registrer it itself (as in it does not continue the code)
sometimes it can registrer it and sometime it doesn't.
I could not find any solutions for it.
some of the code is in danish (mostly just comments)
...ANSWER
Answered 2020-Nov-17 at 10:47The most likely fix was to change the hotspot from my phone to a pc.
My phone most likely did not give it an IP adress...
QUESTION
I've created chart that shows temperature from past 20 minute. Data is obtained via GET request from my Thingspeak meteo station. How could I send new request every 10 seconds and update only data in chart.
I think chart.update() would work, but I have no idea how to implement it :/
Here is some code:
...ANSWER
Answered 2020-Oct-29 at 20:09basically you need access to chart so if you move its context/scope to be outside of the function then you can access it from another function....
something like....
ommited some of the code as well this is the core bits..
QUESTION
When running a program on the Raspberry Pi Zero W, which involved the RPi Camera, I encountered an issue. This was based on the Joy Detector Demo, from the AIY Kit. Normally, it would change LED colours and make noised based on camera facial input (emotions), but I also added a part which would stream the extent of joy to ThingSpeak.
The expected output was for the program to run, using the camera , instead the following message appeared:
...ANSWER
Answered 2020-Aug-10 at 15:00you should enable the camera. In command-line type 'raspi-config' and then enable camera
QUESTION
StackOverflow fellow developers,
I am doing some Arduino coding to working with measuring Fine Dust Monitoring Device,
However, I have a question regarding with If-statement.
In the code below, I added nested-if statement in the while loop, and some reason,
...ANSWER
Answered 2020-Jul-06 at 15:55You may be getting unexpected behavior due to floating point comparisons or may be due to some unhandled cases, or may be because RunningMedian::getMedian()
is changing on any/every condition check. Another possible reason is maybe RunningMedia::_cnt
is not more than 0.
Also I would recommend updating your library to its latest version (v0.1.15).
Try putting this code inside your while
loop:

I want to connect ESP32 to demo thingsboard using MQTT and I've used umqtt.simple to connect to it but there's a problem. Whenever I try to connect it gives me either this (File "umqtt/simple.py", line 99, in connect), OR (File "umqtt/simple.py", line 57, in connect IndexError: list index out of range), which I believe they are the same. Although when I tried to connect ESP32 to thingspeak (with some edits) it connected, sent and received data very well. So what is the problem?
My code:
...ANSWER
Answered 2019-Dec-05 at 16:20The problem seems to be, that umqtt from micropython only supports no authentication or user AND password authentication. So I've edited my code as follows:
