[FEATURE REQUEST]Simple example to show Values from MQTT topics #557

Closed Raudi1 closed 1 month ago

Raudi1 commented 1 month ago

I'd like to use AWTRIX to display some values from EVCC on my Ulanzi display. There's already a flow, but I can't get it to work. And I don't seem to be the only one: https://github.com/evcc-io/evcc/discussions/10283

EVCC is already publishing the data to the broker under the topics evcc/site/homePower and evcc/site/pv/1/power etc.

It would be great if there was an easy example how to subscribe to an MQTT topic and display the values.

There is no example, because it doesn't work as you think. You can't just subscribe to another device because Awtrix doesn't know the data structure and how to parse it. Instead you need to send the data in a predefined and well documented structure.

Flow are just community automations for several Smarthome systems. In your case N8N. But you can use any other system wich can send http or mqtt request.
