# AMS <-> MQTT Bridge
Orignally designed and coded by [@roarfred](https://github.com/roarfred), see the original repo at [roarfred/AmsToMqttBridge](https://github.com/roarfred/AmsToMqttBridge)

This repository contains the code and schematics necessary to build a device to receive and convert data from AMS electrical meters installed in Norway. The code can be used on both ESP8266 and ESP32, both as custom build devices or built from readily available modules. It reads data from the HAN port of the meter and sends this to a configured MQTT bus.
