HomeWizard gas values/sensors not available anymore

[vincentvdb1987]

The problem

Few days ago my digital gas and electricity devices were replaced with new onces since the previous stopped communicating. Since then I don't get the GAS information anymore from my HomeWizard P1 meter. I tried removing the integration, restarted HA and add again but still the same. I also restarted the P1 meter multiple times. The gas values are still available in the diagnostics file but I don't have any sensor available in HA. Previously the integration showed 3 devices (P1 electricity, Gas, Water), now only P1 and water.

What version of Home Assistant Core has the issue?

2024.5.3

Hey there @dcsbl, mind taking a look at this issue as it has been labeled with an integration (homewizard) you are listed as a code owner for? Thanks!

I see that also the "P1 meter energy import" and "P1 meter energy export" is not working the same as the "sensor.p1_meter_total_energy_export" and "sensor.p1_meter_total_energy_import" I had before... The Energy dashboard is showing completely wrong information with these 2 new sensors. :(

@vincentvdb1987 check if can reach your meters local api on <ip-of-meter>/api. If you can not try unplugging the meter and plugging it back in and check again. This fixed it for me just now.

[vincentvdb1987]

I can reach it without issue and get this info: { "product_name": "P1 meter", "product_type": "HWE-P1", "serial": "xxxxxx", "firmware_version": "4.19", "api_version": "v1" }

The P1 meter is also available in HA but I only get electricity and water values, no gas information

@Willem-Dekker, I think you issue is https://github.com/home-assistant/core/issues/87432

@vincentvdb1987, can you see if you still have some old entities alive in your instance? Maybe you can (backup and) remove those. I suspect we do not handle unique ID's + migration properly (introduced in https://github.com/home-assistant/core/pull/100684)

[vincentvdb1987]

@DCSBL thanks for the reply. I checked and indeed some old entities were available, I deleted them and reloaded the integration but still no luck. Anything else I should do?

[DCSBL]

Oh, I've just checked your diagnostic file. I see two things that may be concerning;

1. I cannot see your gas meter listed, only your watermeter. This may be the root of your problem → Your supplier fkd up and did not connect your gasmeter properly.
2. I do not like the unique \u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000 string, this should be something more readable.

If you have discord, can you message me privately with the result of http://<ip_address>/api/v1/telegram. Or feel free to redact some data and paste it here.

[vincentvdb1987]

I had the same thought that they fkd up but in the diagnostics file I see this: "total_gas_m3": 0.053, "gas_timestamp": "2024-05-16T12:57:37", "gas_unique_id": "REDACTED",

So it looks to me like there is something available? Also when I use the HomeWizard app I see both electricity and gas usage without issues.

I am not using discord so I paste the info here, no idea if there is anything sensitive? :-D

Your gasmeter and watermeter both have the EAN 000000000000000000, this should not happen. I am not sure if this is something new or something your installed messed up. I have not seen this before.

Because we use this value as unique_id in Home Assistant, it will conflict as both IDs are the same.

So we have to figure out if this is something we could/should fix is to determine if this is new behaviour from Fluvius or just one installer that had pressed the wrong button or something. Can you get in contact with Fluvius? Just send them the telegram and tell them 0-1:96.1.2 should contain something unique.

[vincentvdb1987]

I called with Fluvius, apparently they have some issues "in transition" where a lot of EAN numbers got locked, that's why I get all 0. They are working on but it can take some months :-| Gonna contact water supplier and check if they can change the 0's, if so, then the gas is the only one with 0's and it should work again, correct?

[DCSBL]

Okay, bummer! Having one that is unique should do the trick indeed. (Maybe you have to remove the 'old' 000-watermeter first.)

It may be possible to add something to fix this issue (temporary) as this may cause issues with more customers in the near-future. We may create an unique_id based on the smart meter EAN + 'It is a gasmeter', that combo is pretty unique in most cases 🤞. I will ping the core developers to join the discussion.

[vincentvdb1987]

That would be indeed a good workaround since I don't believe that the water-people are smart enough to program a serial number in that thing :-s Support is not the best thing on these smart-devices unfortunately. Thanks for the effort, would be nice to get it working again like that!

EAN+'it is a gasmeter' should indeed be unique in most households, unless in apartment or business buildings with multiple devices where the owner wants to control everything :-)

[DCSBL]

Proposed a fix in https://github.com/home-assistant/core/pull/117940

[vincentvdb1987]

Nice! Thanks a lot!!! I am always willing to install the fix and test it, if you can guide me through the installation :-)

[DCSBL]

@vincentvdb1987 as beta week is coming close I think it is the best to wait for that. Otherwise you have to set up a development environment.

Besides this, can we add you to a firmware beta? We have developed a fix which should solve this issue. If so please fill in this form and I will add your P1 Meter to the beta channel.
