I’m using a NodeMCU for my AQI project. Initially, everything was working fine, but now when I try to update, my ThingSpeak website isn’t showing any new data. It only shows my last entry from three months ago.
The serial monitor indicates 'Data sent to ThingSpeak,' but my channel is not displaying any updated data. Instead, it’s showing 'Field value unavailable.

You may accidentally be sending data with a date format that is very old on accident (ive done this before) or you might not have the field enabled on your channel settings? I would initially try updating manually through the browser address bar (see the api keys tab of your channel view for the syntax) and then try looking a the output of your node MCU code to see what is sent to ThingSpeak and trying that syntax manually to see if it works.
