MQTT Device Configuration and Automation Tips

Hello everyone, I’m currently transitioning from ioBroker to Home Assistant and have been exploring MQTT integration. Setting up MQTT devices has been quite promising, but I’m facing a specific challenge with data utilization. I’ve successfully received data on the MQTT topic, but I’m unsure how to process and use it within HA effectively. For instance, I have a value of 550.01 representing my household consumption, and I want to leverage this data for further automation. Does anyone have insights or tips on how to configure this properly? I’d love to hear your experiences or any workarounds you’ve discovered. Looking forward to your suggestions!
