Slimme Lezer / Smart Reader

Current version: Slimme Lezer v1.0.2

The Smart Reader (successor to the P1 Wemos v3.1) is based on an ESP-12. It has a build in logic inverter which makes the data from the P1 port readable for systems like Home Assistant, DSMR-reader, Domoticz, P1 Monitor and other systems.

The ESP-12 has a build in inverter, yet not all firmware can use that functionality. Therefore the reader has a logic inverter to make it accessible for everyone.

The modules are designed to work with DSMR 5. Working with DSMR 5 means that the Smart Meter can deliver enough power through the P1 port to power the reader. Therefore no extra power adapter is needed to work.

The module is compatible with older Smart Meters, having DSMR version 2, 3 or 4. As older versions of DSMR can’t provide enough power through the P1 port, an external power source is required to work. That can be any micro USB adapter which is capable of delivering 250mA.
