DomesticHotWaterProduction does not report Water Consumption and Volume Estimation in Overkiz

[lorban]

The problem

I have a AtlanticDomesticHotWaterProductionV2_CV4E_IOComponent hot water boiler which works nicely except for these two entities:

• Water consumption is displayed but it's value is always Unknown.
• Water volume estimation at 40 °C is grayed out and This entity is unavailable is reported while I'm reasonably certain the boiler supports it.

What version of Home Assistant Core has the issue?

2023.6.2

Hi everyone,

Exactly same case and same issue with these 2 entities. Any updates or improvments ?

Many thanks in advance, BR

[iMicknl]

Please add your diagnostics. Does it work in the CozyTouch app?

[iMicknl]

@f0xbr0wn, @lorban, can you please add your diagnostics? Otherwise I have to close this issue.

1. If your device already shows up in Home Assistant, go to your integrations page and select Overkiz, your hub and the device. Press the 3 dots and select "Download diagnostics. Otherwise, go to your integrations page and select Overkiz. Next to your hub, click the 3 dots and select "Download diagnostics".

2. Attach your diagnostics (JSON file) to this issue by uploading the file in a new comment (drag and drop supported).

[lorban]

Here it is: config_entry-overkiz-5da932967dc69a9590a4a27f5c9503f6.json.txt

Thanks!

[iMicknl]

Do you see this status in the CozyTouch app? I see that core:WaterConsumptionState is present in your definition, but not in your states. core:V40WaterVolumeEstimationState is present in your states and should show 18592 in Home Assistant.

The 'Water volume estimation at 40 °C' sensor is disabled by default and you need to turn this on in Home Assistant by clicking on it and selecting 'enable'. Is this a sensor that is used a lot, and should we include it by default?

[lorban]

I have some graphics reporting the water consumption for the week/month/year in the CozyTouch app, does that mean there is no way for HomeAssistant to get this data?

Now that I enabled 'Water volume estimation at 40 °C' its value is 18592 L. I'm not sure what this value means, I thought it would indicate how much hot water I have left in the tank, if I take water at 40 °C.

Regarding your question if that sensor should be enabled by default, my opinion is that it should as I see no reason why a specific feature would need to be explicitly enabled while the other ones are by default.

[iMicknl]

@lorban I have some feeling that it is disabled by default because we couldn't figure out what 18592 L means. Do you have such a big tank?

As you can see in your diagnostics, these are the raw values we get from your device. Besides what is available in your file, we cannot add any extra sensors.

[lorban]

My tank is a 200 L one, so my guess would be that this reading's unit is centiliters: 185,92 L looks reasonable.

I'll monitor this value over time to see how it varies over time.

Thanks for your help!

[iMicknl]

Thanks @lorban! Can you perhaps check in your official app if the same value is mentioned somewhere? Happy to change the unit for this one to CentiLiter.

[f0xbr0wn]

Please find in attchment. Yes it works in Android app.

Thanks in advance, Bregards, config_entry-overkiz-468bbd862383527549db48047dd030ac.json.txt

[iMicknl]

@f0xbr0wn how many liter is your tank? Your value is 26958 for Water volume estimation at 40 °C.

 {
              "name": "core:V40WaterVolumeEstimationState",
              "type": 1,
              "value": 26958
            }

[f0xbr0wn]

Mine is a 250 Liters

[iMicknl]

Interesting, so it is not in centiliters... Because 269,58 wouldn't fit in that sense.

[lorban]

@iMicknl if the temperature in @f0xbr0wn 's tank is over 40°C, this may still be an accurate reading: he may be able to pull 269,58 liters at 40°C out of his tank if it contains water that's much hotter than 40°C.

I'm not saying the unit definitely is cL, I'm just not ruling this out yet.

[lorban]

@f0xbr0wn I checked my paperwork and when I got my tank (an Atlantic Explorer V4), I had a choice between these two sizes only: 200 and 270 L.

Could it be that your tank actually is a 270 L one instead of a 250 L one?

[iMicknl]

@lorban that could explain it as well! I will mark it as centiliter and add it by default.

[f0xbr0wn]

@lorban no, it's a 250 L capacity. Only 2 models available for Atlantic Aeromax v5 VS : 200 or 250L.

Hi everyone,

I do have same issue with 'water consumption' that is not shown (it does in Cozytouch app). Anyone a solution to get these values in Home Assistant as well?

Thanks in advance.

Regards, Gerben

[iMicknl]

@gvansteeg please add your diagnostics + a screenshot of the current value in the CozyTouch app.

[gvansteeg]

@iMicknl, thanks for your reply.

Attached are diagnostics and a screenshot of the 'Warmwaterverbruik' part in Cozytouch app.

Please let me know if you need more information. Regards, Gerben

Hi everyone,

I also have the same issue with 'water consumption' that is not shown (it does in Cozytouch app). I have added the sensor 'Water volume estimation at 40 °C' and also see a strange value, but the Water consumption field still remain 'unknown' Anyone a solution to get these values in Home Assistant as well?

Thanks in advance.

Hi everyone,

Water volume estimation at 40 °C, give us a lot of confusion.

Something clear is that water heater can produce water at 40°C more than their capacity. Because it's the result of mixing hot water of the boiler with cold water (into your shower mixer). As you can see in the manuel, my 120l water heater could "produce" 207l of water at 40°C.

I think that core:V40WaterVolumeEstimationState returns an estimated value for the amount of water at 40°C produced by the boiler. It seems that this value is cumulative and increases every day. It may be equated with consumption (did Atlantic do it in the Android App?), but it shouldn't be because if after a certain time the water temperature drops inside the boiler, the boiler heats up and this value increases without having taken any hot water.

I ran a few tests and found that the value went up and down is core:RemainingHotWaterState . As this value is beyond my water heater capacity, and near the value of the manual (the water heater return 208 for 207L in the manual), I think this value give the V40WaterVolume available. But this state is not available for all water heater of this issue. overkiz-c929b452d11011669b3ec40de555a1c6-MALICIO-338da5a98907175791460b197aa669a2 (1).json

Hope this help!
