Real-time Environmental Monitoring

May 14, 2021 at 4:46 pm #28844
Participant
I use WifiServer instead of WebServer which means that the original code from the opensource version uploads it data to uRadmonitor on a different manner then what I’m currently using to do a HTTPS using the WifiServer options.
Below is my current code which works for uploading it to another platform (Radmon) at this moment.
Would love to also getting it to work to upload it uRadmonitor to provide the other sensors that I can monitor already through my build in webserver page.
The json query will take a bit of work but I’m hoping I will be able to do that on my own. My main concern now is how to do the upload to uRadmonitor.
Thx!
