The dashboard of an energymeter connected with LoRaWAN and MQTT
GAHE GHDS100E Energy Meter is equipped with RS485 Communication. Readings are retrieved by ESP8266 (Wemos Mini) running Modbus RTU library, then send the data directly to Thingspeak every 15 seconds.
It collect's the data of a density based traffic light controller.
