+#### Reading the meter via a IEC62056-21
+
+The IEC62056-21 is a common protocol not only for electric meters. It uses an infrared port to read data.
+[Aquaticus](https://github.com/aquaticus) has created an [ESPHome component](https://community.home-assistant.io/t/new-iec62056-21-component/555236) for reading this data. [PiggyMeter](https://aquaticus.info/meter.html) is a complete project that allows easy installation.

 #### Using (Smart Message Language) interface
 
 In countries like Germany, SML (Smart Message Language) is used typically. ESPHome's [SML (Smart Message Language)](https://esphome.io/components/sml.html) is one way to integrate it. If you prefer to integrate it via MQTT, [sml2mqtt](https://github.com/spacemanspiff2007/sml2mqtt) is another open source option.
