SlimmeLezer Mini

The SlimmeLezer Mini is the successor from the SlimmeLezer+. The mini is because of it’s format, the pcb measures 16 x 41 mm. Don’t be fooled by it’s size, it’s powered by an esp32c3 and therefor more powerfull than the esp8266 bases SlimmeLezer+ yet more power efficient.

SlimmeLezer integrates your energy meter with P1 port seamlessly into Home Assistant. Plug and play, no coding necessary. It comes pre-installed with ESPHome code. After joining it to your WiFi it will be recognized in Home Assistant and can be added easily.

The SlimmeLezer is designed to work with DSMR/ESMR 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.

Older Smart Meters with DSMR version 4, 3 or 2 will work to, but will require extra power via the USB-C (not included).
