I recently started using the RFXcom RFX-433EMC USB/Wi-Fi/MQTT with HomeAssistant. You can flash different firmware versions in it. I’m using the RFX433EMC_MQTT_Wi-Fi firmware. Within HA, I haven’t activated the Mosquitto broker because I have a Mosquitto broker running on another system. I do use MQTT integration within HA.
Now for my problem: After configuring everything correctly, my RFX433 appears correctly in HA, and I’ve enabled the auto-discovery option to integrate my light switches that way. This works fine; as soon as I send the on/off signal with the remote control, the switch appears in HA. However, when I try to control the switch from HA, nothing happens. Do I need to configure anything after integrating?
