ESP8266 MQTT not received [RF-Gateway]

Hey together!

I installed the OpenMQTTGateway on my WeMos D1 mini and connected both 433 receive and transmit module. The board starts up fine and connects with the MQTT Broker, it also sends messages whenever I press a button on my remote, but when I publish something in the 433toMQTT topic, nothing happens, no switching of the outlet and no reaction on the serial console.
Thanks for your help

Okay, I found an error message in the serial console:
failed to open config file for writing

Okay, RTFM
When you publish to home/433/433toMQTT, then nothing happens, because you have to publish to home/433/commands/MQTTto433
epic facepalm

Glad you found the way yourself ; -)
