Power consumption values are different to Multimatic App
If I use the "VWF 88/4 CENTRAL_HEATING CONSUMED_ELECTRICAL_POWER" sensor as an individual device on the energy dashboard it's comfortable to show power consumption for each day. But if I compare these values with the multimatic app they don't match. For example for yesterday the app shows 7kWh, the dashboard 5kWh. It's different for all days i compared. Do you have any ideas?
Hello,
I don't have any idea right now, but let's check that. I don't have any consumption sensors myself, so this is quite hard or me to test.
Consumption sensors are refreshed every 30min. So you might have different values if, for example:
- consumption for day 1 (between 00:00 to 23:59) is 5kWh
- sensors are refreshed at 00:05 (I mean here, just after 00:00). So this consumption is considered day 2 for HA. So might see some difference here.
- So day 1 will be 5kWh and day 2 xxkWh + 2kWh (that are actually from day 1).
Can't you check, for example, for one week in both HA and multimatic to ensure values are closed to each other ?
I can also release a new version which will fetch consumption sensors more often (but it will only reduce the error margin, there will still be some).

Hey, thank you for your fast answer. To check this I take some screenshots from the sensor graph in HA and the mutlimatic App.
October 21-23
As you can see the sensor is only fetched once a day around 12 am. So you are right, the value is half from the past day and half from the current.
So, last version https://github.com/thomasgermain/vaillant-component/releases/tag/1.12.9 includes a higher refresh rates.
Maybe values should be closer to what can be seen in the app.
Please let me know how it looks !
I tested the last version for some days, but unfortunately it behaves the same. Data is only fetched once a day around midday. (Only one day is a little of because of a local network issue.
Anything else I can do?
I released the 1.14.0b1 (beta) version.
As suggested in another issue, this issue might be related to the server cache. I added some headers, so the server should not use its cache. There are two notes:
- I don't even know if the difference between the integration and multimatic is due to the cache
- I can't test it since my installation is not compatible
Bad news. Thanks for trying to solve it via the new headers. Unfortunately, the value is still updated only once a day. Please let me know if I can help with testing or troubleshooting in any way.
I am running this, too. I see several changes per day, which roughly seem to correspond with the heating phases for zone 1.
Good Morning! I think I have a similar problem. In the app yesterday I had a largely constant solar production (VRC 700/4 CENTRAL_HEATING SOLAR_YIELD). In the energy dashboard some of it is missing. Instead, there is a solar yield today that was definitely not physically present (totally cloudy). Maybe this information will help somehow. If I can test something, I will be happy to do so. Many greetings Thomas
Oops, no I have installed the latest release version (1.13.0). I will install the new one and then test it. But I need some sun for that, and unfortunately that doesn't look good here in the next 3-4 days. But I'll give a feedback.
