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

Hi Fabian,

Not sure why I get this message…
Seems it does not want to accept a 0.34 value, only whole value’s seem to be allowed as input.
Any idea how I can change that?

my card-code:

Never mind…

Adding step to the input_number config solved it for me:

input_number:
t2_energy_cost:

min: 0
max: 100
step: 0.01

you need to check if the , (comma) is working, I have a . (point) as input number

Does de P1 meter reset at 10.00 pm? This happens every day.

Hi @DCSBL ,
Is it planned to include the new watermeter as well?
Quite sure I would buy it if integrated in HA…

DCSBL · June 30, 2022, 5:55pm

Of course

The watermeter is added to the API documentation and most of the things for this addition are ready and tested. I hope I have everything completed soon to open a PR so that the watermeter can be used in version 2022.8, just before they are shipped!

Friedrieck · June 30, 2022, 6:35pm

Impressive, thanks!

Tash · June 30, 2022, 8:14pm

Hello, would you happen to know if this water meter is compatible?:

On the webpage I can see Itron, Elster or Sensus as being compatible, but there is no reference to the model. Since I have another brand installed (quite old), I plan to add a second water meter (see the picture), but I would like to be sure of the compatibility before anything.
Thanks for the great work! The P1 works just great and the integration with the ha is very well executed.

DCSBL · June 30, 2022, 8:32pm

That is something for HomeWizard Support, please ask it there (the chat icon on the bottom right on the website)

Thanks for the compliment

Tash · July 1, 2022, 7:52am

Great! I just asked them, they say it is compatible.

@jvbragt : Just checked, but mine seems to be updating hourly just fine… local issue ?

vtriet · July 3, 2022, 9:19pm

@DCSBL : Today I received the kWh meter as a replacement for the pulse counter + HomeWizard Energy link I had installed since 2013 … kinda replacing the HomeWizard with HA, sorry !

Installing went smooth, only for me to mess up the input/output wiring causing the App (setup for Solar) not to register energy ‘production’ … so after an easy switching the wires it looks great. (a mention in the install leaflet would be nice.)
Tonight I wanted to see if I can connect to HA but noticed that currently its connected to my WiFi SSID using a DHCP address … Ideally I want all these types of devices to have a fixed IP address outside the dhcp scope, any way to set this up ? (I don’t think the current Ziggo router supports IP assignment based on MAC addresses)
Thx ! Richard

DCSBL · July 4, 2022, 4:38am

No worries! The ‘old’ HomeWizard is +10 years old, technology needs to be replaced :). Nice to see you choose for a HomeWizard device again…

This is mentioned as basic installation instruction. But maybe we can make it more cleare somehow. Thanks for the feedback!

All basic routers should have something to assign fixed IP addresses. I remember you can select something like ‘advanced settings’ or something. Then just powercycle your meter. The kWh meter does not support any other IP configuration than DHCP.

vtriet · July 4, 2022, 2:37pm

Thanks, I will look into the DHCP issue and see if I can fix that with the Ziggo router.
To follow up : should the kWh meter automatically be visible on the Energy Dashboard ? Or do I need to manually add that ? (maybe a noob question, sorry)

DCSBL · July 4, 2022, 3:31pm

Yes, after adding the meter to Home Assistant, you need to add the meter to the dashboard (via settings → dashboards)

vtriet · July 4, 2022, 7:55pm

Worked like a charm, thx !!

The P1-meter and kwh-meter were working very well until I discovered that they weren’t recognized by HA anymore since about 2:30PM in the afternoon. Nothing had changed and both devices are online and in the HomeWizard Energy app show recent information.
When trying to re-add them and entering the (fixed) ip-address I get ‘unexpected error’. Now it’s impossible to monitor the energy-usage anymore. What can have caused this, and better: how to solve? I was on 2022.6.7 on Docker. (upgraded 2 days ago) and tried with the latest dev 2022.8.something, but same issue.
And local API is enabled in HomeWizard app

DCSBL · July 6, 2022, 6:25pm

Try to power-cycle your P1 meter

DikkieDick · July 6, 2022, 8:23pm

I did, didn’t solve it. Powercycling the kwhmeter is a bit more tricky.

DCSBL · July 6, 2022, 8:53pm

A few things;

To give a bit more context for my last post. There is an known issue that the Energy devices do not handle an unclosed API connection properly. If this occurs to many times the device won’t accept any new connection, but this should be solved by a reboot. Try to see if this is the case by going to http://<ip_address>/api. You should see valid JSON and no error.

Both devices are lost at the same time. That indicates to me that is is not related to the device but to your network or Home Assistant so we can rule the previous idea out. Can you check if your installation is not changed somehow (like a Docker update that blocks some traffic or a (new) router setting)? You also can try the same API endpoint to see if the device is reachable from that installation.

You also mention HA 2022.8. Are you sure? The latest is 2022.7, i’ve tested this version a moment ago and I see no issues. Configuring and fetching data just works fine. Can you see something in the log for the unexpected error message?
