EASUN ISOLAR SML III 5.5kW - Problem about esphome-pipsolar HOT 6 OPEN

Please double check your wiring. The incoming bytes (garbage: \xFF\xFF\xFF\xFF\xFF\xFF\xFF) looks like bad grounding (GND).

Is the inverter compatible with the SmartESS wifi dongle?

from esphome-pipsolar.

If you use esp32:
tx_pin: GPIO16
rx_pin: GPIO17

or ESP8266:
tx_pin: GPIO1
rx_pin: GPIO3

# Enable logging logger: baud_rate: 0
I saw the same on pins GPIO4 and GPIO5

@ZVlog Any updates? I would like to close the issue. Did you see @BeckoPopov recommendation?

Please try to attach the inverter to GPIO1/GPIO3 and disable the logger on GPIO1/GPIO3 by baud_rate: 0.
