(Partial) NEPViewer replacement for desktop/laptop computers
Utility files to view selected data uploaded by NEP micro inverter systems to the cloud, instead of using the official iOS/Android NEPViewer app. (Note: This also works for rebranded NEP micro inverters, e.g. those distributed by Anker or Nuasol.)
Temporarily disable CORS in your web browser (e.g. using CORS Everywhere with Firefox, which thankfully automatically enables the CORS security feature again on each start of Firefox),
then load NEPviewerCR+.html, with your micro inverter's serial number appended in the address like this file:///.../NEPviewerCR+.html?SN=efcdab78. The serial number must be as provided in registering your micro inverter with the NEPViewer server.
Initially the current day's power and energy curves, the most recent seven days', the most recent twelve months', and the most recent years' cumulative energy will be displayed graphically. Using the date selection control in the top left of the screen, the power curve for any other day can be displayed.
Example:
If all you want is a non-interactive plot of a day's power and energy curves, you can also use NEPviewerCR.py.
Usage: python3 NEPviewerCR.py serno [yyyymmdd]
Example:
There's also NEPstatusCR.pl, which can be used on the command line to get the most recent status of a micro inverter registered with the NEPViewer server.
Example:
(Replace efcdab78 with your micro inverter's serial number!)
$ perl NEPstatusCR.pl efcdab78
