ThingSpeak

关注

Hi all, for my postprocessing of measurement data in Thingspeak I have written several functions that I use in Thingspeak visualizations. I would like to save my functions once and use them in all my visualizations (as you would do it in every local Matlab program). However, I haven't found a way to do this in Thingspeak. My workaround is to copy+paste all my functions and parameters in every visualization code. This works, but it is not nice. When you want to update functions or parameter settings, you need to open every single visualization and do the changes manually. Any help is appreciated. Thanks, Christoph

I want to write information for controlling a device in my ThingSpeak channel, can I store the control parameters in ThingSpeak and read all of the paremeters at once back to the device? I'd like to be able to read multiple fields without having to make multiple calls to the ThingSpeak readfield command on my Arduino or esp32 or ESP8266. Is this possible?

I would like to be able to issue this: https://api.thingspeak.com/update?api_key=myapikey&field1=634567 from an android app. Do libraries exist that I could import into a android java project to make it easy? Or what would be the raw java code to do this?
