A simulator that mimics DSMR smart meters. Usefull for testing P1 to $protocol devices.
It sends a static telegram every second at the TX pin. This telegram is the example telegram found in the P1 companion standard (https://www.netbeheernederland.nl/dossiers/slimme-meter-15/documenten) It blinks the builtin LED when sending a telegram.
It was built using a Wemos D1 mini, because I had one close at hand. :-)
Future updates will include an acurate timestamp and correct CRC.
