Może komuś się przyda

Aby zintegrować dowolny falownik który współpracuje z chmurą globalapi.solarmanpv.com trzeba napisać na adres customerservice@solarmanpv.com prośbę o odblokowanie API

W odpowiedzi otrzymamy regulamin. Należy odpisać, że przeczytaliśmy i że się zgadzamy.

W kolejnej odpowiedzi otrzymamy :
API ID:xxxxxxxxxxxx
API Secret: xxxxxxxxxxxxxxxxxxx
Dane te będziemy potrzebować do naszego skryptu

W domoticzu tworzymy czujnik "Electric(Instant+Counter) i w skrypcie podajemy jego IDX
Oto skrypt xxx.py który umieszczamy w katalogu /domoticz/scripts/python

Nadajemy skryptowi prawa wykonywalności oraz dodajemy do Crontab wykonanie skryptu np. co 5 minut

#!/usr/bin/env python3
