Smartyreader is an open-source printed circuit board by weigu1, from the weigu1/SmartyReader repository on GitHub, published under the GPL-3.0 licence. It is a 2-layer board of 57.1 × 30.5 mm with 23 parts on 23 nets, routed with 165 tracks and 6 vias.
It is built around the WEMOS D1 MINI. Its parts include 6 resistors, 5 connectors, 2 capacitors and 2 transistors. It belongs with the ESP8266 boards of this library.
Because of the EU Energy Efficiency Directive from 2012 the gas and electricity Distribution System Operators (DSO) in Luxembourg replaced there gas and energy meters with smartmeters (named smarty :() from Sagemcom (T210-D).
As it seems the same smartmeters are deployed in Sweden, parts of Austria and the Netherlands.
These smartmeters have a user port that delivers 10 second data (RJ12 connector under the green lid). The P1 data output communication protocol and format is specified in the Dutch Smart Meter Requirements v5.0.2 . The solution deployed in Luxembourg includes an additional security layer standard that is conform to the IDIS package 2.0 requirement. The encryption layer is based on DLMS security suite 0 algorithm: AES128-GCM. More information can be found in this document.
The Smartyreader is a simple board designed with KiCAD and decrypting the smartmeter data with an ESP8266 (Lolin D1 mini pro). The data is then published over MQTT via WiFi or Ethernet. A new version allows also to use LoRa or LoRaWAN.

The 21 most common of 23 parts.
It measures 57.1 × 30.5 mm and has 2 copper layers, 1.6 mm thick.
23 parts, built around the WEMOS D1 MINI. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
From the weigu1/SmartyReader repository on GitHub, at the commit this page was made from: the board is KiCAD/smartyreader_v1_1/smartyreader.kicad_pcb and its schematic KiCAD/smartyreader_v2_2_lora/smartyreader_ng_lora.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
