Olimex ESP32-POE-ISO no connection to inverter when ethernet enabled

[quaternionma]

My config:
NRF24L01+ connected with the UEXT interface of Olimex ESP32
MISO=GPIO15
MOSI=GPIO13
SCLK=GPIO16
IRQ=GPIO2
CE=GPIO4
CS=GPIO5

This is the relevant portion of the device profile:

"name": "Olimex ESP32-POE",
"nrf24": {
"miso": 15,
"mosi": 13,
"clk": 16,
"irq": 2,
"en": 4,
"cs": 5
},
"eth": {
"enabled": true,
"phy_addr": 0,
"power": 12,
"mdc": 23,
"mdio": 18,
"type": 0,
"clk_mode": 3
}

If the LAN cable is disconnected and the ESP32 connects through WIFiI the DTU can poll the data from the Inverter (HM-600)

However if the ESP32 is connected via ethernet (via DHCP) the DTU gets in trouble getting the data from the inverter.
In both cases an external power supply is used, so no POE is activated

Any ideas?

Same here,

with WiFi and USB-Power everything is fine.

Plugging in the Ethernet-cable (with or without POE) and the inverter "is gone"...

u can see in the logs that there are no interrupts received anymore...

:-(

hope somebody has an idea

thx kai
