im so sorry but I don’t understand it. like I wrote I can see the examples in my Mqtt broker.
when I change in my broker the messages I can also see in the log from the mirror that it changed this values but how can I trigger with this a alert for example or a notification? what I have to configure? in the config.js file by the module: MMM-MQTT-Bridge? when yes what? I copy the examples already.
