=head1 NAME

Outputs the total and daily production, DC current, DC voltage, DC power for the inverter and the connected panels from Solarman (Smart) API.
To get the API-Keys a E-Mail to customerservice@solarmanpv.com is needed.

=head1 CONFIGURATION

Tested with a "Deye SUN600G3-EU-230 600W" inverter.

Dependencies:
 - curl
 - jq

plugin config:

  [solarman_api_inverter]
    env.SLRM_APPID 2XXXXXXXX2
    env.SLRM_DEVICE_SN 2XXXXXXXXX6-1
    env.SLRM_MAIL "XXXX@YYY.de"
    env.SLRM_PASSWORD 'aXXXXXXXXf'
