HomeWizard Energy (Wi-Fi P1 meter, kWh meter, Energy Socket and Water Meter)

The info is available in the last_period attribute of your daily utility meter. If it’s not enough, you can create a template sensor fed by that attribute.

Hi, any update on this functionality? Thanks!

Faecon · April 18, 2023, 9:14am

You lost me 🫣

Add this to configuration.yaml and adjust it to your utility meter id.

template:
  - sensor:
      - name: "Verbruik gister"
        unique_id: "yesterday_energy_usage" # Something unique, self defined
        unit_of_measurement: "kWh"
        state_class: measurement
        device_class: energy
        state: '{{ state_attr("sensor.verbruik_vandaag", "last_period") }}'

Hello,
I have an issue since monday with the water meter.

the active_water_usage sensor does not relay any informations

despite the fact that all the others sensors works well

any idea ?

thanks !

DCSBL · April 20, 2023, 5:33pm

There is a lot that could go wrong, without having information about your situation/configuration.

Some ideas to think about:

Does the HomeWizard app show the same ‘missing’ information
Have you tried a reboot or something?
Is there something changed since ‘Monday’?

n3xT · April 20, 2023, 6:48pm

thanks for your support,

Unfortunately, the Homewizard app does not show the active_water_usage, just the total, and value are the same as HA.

I’ve updated HA Core from 2023.3.6 to 2023.4.5 and OS to 10.0 yesterday, so yes already rebooted a lot of time.

What is the advantage to see the voltage ? What can you see or learn from it ?

Faecon · April 21, 2023, 8:21am

Is it possible to get the date out of the “peak demand current month” ?

@Faecon
Is it possible to get the date out of the “peak demand current month” ?

Opened Add 'Last update' timestamp attributes for timed HomeWizard sensors by DCSBL · Pull Request #91837 · home-assistant/core · GitHub to allow users to do this.

But you have to create a template sensor again, so time for you to practice

Hi,

So far I have not been able to get this working.
I put this piece of .yalm in the folder configuration.yaml. But I still can’t get it to work. Can someone help me with this?

Hi, Help needed with the Homewizard P1 meter.

I noticed with one of the updates when the homewizard P1-meter loses the WiFi connection values of some sensors are filled in when there is no data or time out errors.
In the past there was no problem, but when I disconnect the P1 meter my monthly counting is doubled as soon as new data is received.
I made special month sensors with kWh and Euro, because we receive a discount every day. (every day same amount)

My configuration.yaml for the energy sensors is:

recorder:
db_url: mysql://hass:[email protected]/homeassistant?charset=utf8mb4
purge_keep_days: 365

Hello!

Using the P1 meter now for a while, but since a week we have solar panels and i can see in the P1 meter that we exported about 100kWh, but when i look in HA it is saying ‘disabled by intergration’ and even by reloading it keeps disabled. How can i fix this?

@DCSBL

DCSBL · June 28, 2023, 12:27pm

Export is disabled by default when export is “0” during installation.

Just hit the and then enable. And wait for a reload.

PyroPath · August 7, 2023, 1:03am

Over the weekend I’ve added a few solar panels to the roof of a little building in the garden. To keep track of all energy collected in one place, I’ve also added a KWh meter on the combined input. Total is now 4kWp. However, now the P1 and KWh meter take turns to stop communicating with HA. I’ve to disconnect power and physically remove the P1 meter from the port. Insert power and the plug back into the port or cycle the breakers for the KWh meter. After that they come back to live. At the same time, my router sees them as connected and the app works without a problem. Any ideas what’s causing this behavior? It only takes a few hours before one of them or both become unresponsive again…

jouster · September 6, 2023, 2:32pm

Is anyone in the UK using the WiFi KwH meter in their UK consumer unit…

Tim_Br · September 30, 2023, 9:57am

Anybody tried to recreate the new energy display?

Jaymade88 · October 2, 2023, 3:55pm

This is the closest that i can get for the circular gauges using circular custom card, which you could probably copy for the other ones as well.

PyroPath · October 2, 2023, 9:34pm

For anyone encountering this issue, it’s something to do with the guest network. I’ve changed both the kWh meter and the P1 meter to the “regular” network and if the WiFi now goes down, both happily rejoin and everything stays working in Home Assistant. Don’t know if it’s ASUS guest network specific, and I can’t understand what’s causing it, bu this fixes it.

DennisStraathof · October 23, 2023, 10:33am

Hi,

Is it possible to gather historic data from the P1 meter or from HA?
Reason for my question is, that I need to switch to a new raspberry with HA installed. I can access the old one, but not able to use it much longer. However I’d like to keep the gathered information of the past 10 months (as you can imagine )

Thanks in advance.
