# AMS Reader
This code is designed to decode data from electric smart meters installed in many countries in Europe these days. The data is presented in a graphical web interface and can also send the data to a MQTT broker which makes it suitable for home automation project. Originally it was only designed to work with Norwegian meters, but has since been adapter to read any IEC-62056-7-5 or IEC-62056-21 compliant meters.
Later development have added Energy usage graph for both day and month, as well as future energy price. The code can run on any ESP8266 or ESP32 hardware which you can read more about in the [WiKi](https://github.com/UtilitechAS/amsreader-firmware/wiki). If you don't have the knowledge to set up a ESP device yourself, or you would like to support our work, please have a look at our shop at [amsleser.no](https://amsleser.no/).

Go to the [WiKi](https://github.com/UtilitechAS/amsreader-firmware/wiki) for information on how to get your own device! And find the latest prebuilt firmware file at the [release section](https://github.com/UtilitechAS/amsreader-firmware/releases).
## Installing pre-built firmware
If you have a device already running this firmware and you for some reason need to upgrade via USB port, you can use a [this web-based tool](https://www.amsleser.cloud/flasher)
If you are using a development board and want to flash a pre-built firmware manually, get the necessary files from the [release](https://github.com/UtilitechAS/amsreader-firmware/releases) section and visit the [WiKi](https://github.com/UtilitechAS/amsreader-firmware/wiki) and have a look at the [Flashing](https://github.com/UtilitechAS/amsreader-firmware/wiki/flashinghttps://github.com/UtilitechAS/amsreader-firmware/wiki/flashing) section
