* DSMR 5 Specification states that the p1 port should deliver 250mA, not all smart meters do so (ZIV is a well known example)

Doesn’t work on a mbus port, almost every meter has wireless-mBus, that’s different, that’s used to connect to gas and water meters.

SlimmeLezer Pro

The SlimmeLezer Pro is the combination of the SlimmeLezer+ and the WT32-ETH01. The Pro is because of it’s functionality. It can be used with WiFi or Ethernet (not at the same time unfortunately, due to restriction of ESPHome). It also has a P1 out, on which you can connect another P1 device. The P1 out can give 5 volt according to specification, but only when powered via USB. It’s based on an esp32c3 and therefore quite powerful and power efficient. The PCB has about the same measurement as the SlimmeLezer: 26,25 x 61,75 mm

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).
