This project allows to send the telemetry data of a Solovoltaic MMI-600 (which is a rebranded NEP BDM-600) to the NEP cloud and additionally to a Home Assistant installation.
Use Arduino to compile and install it on a WT32-ETH01.
In nep-gw.ino
you can change the SSID and password for the access point.
In mqtt.ino
you need to configure the addess of the MQTT server.
The WT32-ETH01 creates a Wifi access point. Configure the MMI-600 to connect to it.
The data is now send over the ethernet interface to the NEP cloud and additionally via MQTT to Home Assistant.
