Setup

1. Copy AmsToMqttBridge\Code\Arduino\HanReader\src to Arduino\libraries
2. Download the following libraries and put them in Arduino\libraries
   • ESP8266WiFi
   • PubSubClient
   • ArduinoJson
3. Set MQTT_MAX_PACKET_SIZE in PubSubClient.h to at least 512 (i used 1024)
4. Edit the following variables in the project:
   • ssid
   • password
   • mqtt_server
   • mqtt_topic
   • device_name

Output example:
