I’m using a P1-dongle with watermeter ([Producten - Smartstuff](https://smart-stuff.nl/shop/)). The device is MQTT capable, see [MQTT | Handleidingen](https://docs.smart-stuff.nl/dsmr-api/geavanceerd/mqtt)  
There is a message for the read out of watercosumption: water\_delivered. /\* FixedValue \*/  
My question is: how can I get this value into my Homey Pro. My goal is to read the daily consumption as well as the total meter reading.  
As you may have noticed, I’m a layman in the MQTT area, and I would be grateful for any help.

I tried to ‘translate’ that to my situation, but I didn’t succeed.
