OSError: [Errno 0] Error

[TomComm27]

I have the following problem when executing the script:

2) config.yaml

device: /dev/ttyUSB1
mqtt:
   url: 192.168.178.XXX
   port: 1883

My inverter is: Solis 4G Mini Single-phase inverter

I use this adapter:

[TomComm27]

Ich habe das problem selber gelöst. Einfach das komplette "config.yaml" Skript verwendet:

device: /dev/ttyUSB1
slave_address: 1
poll_interval: 60
poll_interval_if_off: 600
inverter:
    name: solis2mqtt
    manufacturer: Ginlong Technologies
    model: solis2mqtt
mqtt:
    url: 192.168.178.XXX
    port: 1883
    use_ssl: false
    validate_cert: false
    user: Tom
    passwd: mypassword

I think the "use_ssl: false" and/or "validate_cert: false" was the key changer👍
