Il faut alimenter l’appareil virtuel en données.
Voici un exemple que j’ai implémenté pour alimenter deux compteurs virtuels au départ des données de production et réseau fournies par la passerelle Enphase.

Remarque: Victron recommande, à juste titre, de ne pas utiliser un compteur virtuel comme compteur réseau.
Concernant une sonde météo virtuelle, je viens de faire un rapide test. D’après la documentation seul l’irradiance et la vitesse du vent sont configurables. Voici un code qui pourra t’aider.
