Hi!
I have domoticz running with a p1 cable to track power consumption and delivery. The data is pushed to a mosquitto server.
I thought I’d link that information into home assistant, but it’s not as straightforward as I thought.
I’ve set up the Mqtt add-on. And the logging shows it’s receiving data. However, I don’t have any entities popping up.
Seems that needs to be done manually? Per device?
Can’t find any documentation on how to take this further.
The log

Might be overlooking it but cannot find power consumption/delivery device here? Or should I go more general?
fter searching a bit further, this seems to be an example of a template:
mqtt:
sensor:
unique_id: 'efergy_monitor'
name: 'Energy Usage'
state_topic: 'energy/maintariff'
value_template: "{{ value.split(',')[2] }}"
device_class: energy
unit_of_measurement: W
Not the easiest way to set it up

Also, didn’t anything show up under Settings → Devices & services → MQTT?
I would have expected that… But no…

What is that 10.0.0.4 device?

Ah ok, you’re right; the way it is arranged (on mobile apparently) and the foreign language confused me. 
Got a bit further… Created all sensors:

Now energy dash is still empty… Seems domoticz and home assistant work very differnently.

The energy dash is not updated instantly.
Did you configure it?
Otherwise it would not be 2 different platforms…
