LEO (ließt Energie optimal) can be used to read SDM power meters via Modbus and a single power meter via SML protocol (optical). The reporting of the measured values will be done wie MQTT (WiFi or Ethernet)
- ESPhome: Used for config and flashing
On one side there is a singe ethernet port. This can be used to connect to Ethernet (if configured) The other side has three pairs of connectors:
- input voltage (5V | GND)
- optical sensor (+ | -)
- ModBus (A | B)
For flashing a YP-05 flasher is used. Check the picture how to connect it.
- The Jumper of the flasher must be set to 5V
- The Jumper on the PCB must be next to the blue wire on the PCB
- 1.0
