Arduino Code

FW and libraries for running on various HW

AmsToMqttBridge

The original FW by roarfred, runs a Wifi access point until configured. Uploads data as json to a MQTT server.

WifiFeatherRestBridge

Note: This project is still under development.

Firmware for runninw AMS decoding with off-the-shelf components, so no PCB etching or soldering necessary. Specifially, the sketch runs on the Adafruit Feather M0 WiFi w/ATWINC1500 card and uses the TSS721 M-BUS module board available from Aliexpress.

Arduino Libraries/HanReader

The shared library to read from a serial port and decode the data into packets.

Arduino Libraries/HanToJson

Shared library to create a json structure from the read HAN packets (for the different meter types).
