OpenMQTTGateway - ESP8266 or Arduino program for home automation
|
|
|
|
Act as a wifi or ethernet gateway between your GridFree SUN-2000G inverter and a MQTT broker.
|
|
Send inverter metrics by MQTT.
|
|
|
|
This gateway enables to:
|
|
- publish MQTT data, which are received by RS232 ModBus.
|
|
|
|
Library for read metrics from GWL Power, GridFree SUN-2000G inverter <https://shop.gwl.eu/GridFree-Inverters/GridFree-AC-Inverter-with-limiter-2kW-SUN-2000G-45-90V.html>.
