Basic Ecoflow data charting script. You need to request an API key from Ecoflow Support. Once you have this, replace these 3 sections (YOUR_SERIAL_NUMBER_HERE, API_KEY_GOES_HERE, SECRET_KEY_GOES_HERE) in the script . Then run in any web browser.

Is this still working? I just tried it with my 3 variables and just get a
static chart with no data. My unit is a Delta 2

Dang- I just get a blank chart. I've been trying to contact ecoflow, but they're not very responsive. I also can't use curl- it says device not found currently with the keys they sent me- I assume it's the same issue
Great Job ! Thx a lot !!!!!!
