New Fusebox, P1 Smart Meter KAIFA lost results, please help!

[ThirstyThursten]

Hey Guys,
I bought a house a few months ago and the previous owner installed a Raspberry Pi with Domoticz, the P1 KAIFA information worked perfectly at that time, however I had an electrician change the whole fusebox in the closet downstairs and now I don't get the same information anymore.

He renewed everything above the P1 meter.
At first I could see in Domoticz how much energy my solar panels returned but somehow that information is gone, the graph line went from between 949 - 1260 kWh to a 0 flatline after the renewal of the fusebox.
Somehow this makes me doubt if my Solar panels are connected properly to deliver back to the grid.
Maybe good to mention is that I have 6 parameter/subdevices called Usage_1, Usage_2, Usage_3 and Delivery_1, Delivery_2, Delivery_3 (and ofcourse the gas one.)
Now I know I sed to have most data on Usage_1, Usage_2 and Delivery_3.

I'll add some screenshots below.

So could it be that the electrician made an error reconnecting everything, or could it be he swapped some wires and the value is now in a different parameter?
If it would come to the point where I have to delete the hardware and devices from Domoticz with or without loss of data that would be okay, ofcourse without loss of data would be preferable.

I hope someone can help me since I couldn't find anything about this particular issue.

This is a screenshot of the Graph for Delivery_3 which used to be the Soalr panels.

This is the Graph from Elektra which should be the P1 itself (IDX1) Notice the subtle difference in blue tint in the first graph where you can see Usage_1 smoothly go over in Usage_2:

And this is the P1 data line in teh Devices tab from the Domoticz Dashboard now as you can see there is a lot of different data but it doesn't reflect in the sub devices I'll show below here:

HI, @ThirstyThursten

Let me first explain, what I conclude from your graphs.

1. I see, that you are not on the latest beta, but probably on the stable version, as I miss some option beside the menu.

2. As you use Usage L1, Usage L2, Usage L3 and Delivery L3, I assume that you have a 3 phase network and kWh meter, but that you have a 1 phase inverter for your Solar Panels. Delivery L1 and Delivery L2 is not activated in Domoticz. So previously the inverter has been connected to L3.

3. I also see that, at the time of the screenshot, you do not use any power on Usage L2. It might be, that equipment, connected to L2, used no power, but it also might be that the power for that equipment was delivered by the inverter of the solar panels. In that case it means that the electrician, who did the retrofit of you installation moved the connection of the inverter to the grid from L3 to L2.
To check that, I recommend to activate Delivery L1 and Delivery L2 in Domoticz for the moment.

4. At the time of the screenshot, your consumption was 591 W + 114 W = 705 W. This differs a little from the total consumption of the Smart meter
(760 W).

5. I see a few "strange" things in the graph.
In the graph of last week I don't see any data for Wednesday, Thursday, Friday and Saturday.
If I compare Last month, I see some consumption on 17, 18 an 19 December (Thursday, Friday and Saturday)
Sunday and Monday (today) are correct.

You also mentioned that you noticed the change from Usage1 to Usage 2. Usage 1 is the low tariff (night tariff), which is used in the weekends and nights of the working days. Usage 2 is the higher tariff, you pay during working days.
The switch is at 07:00 h in the morning and probably approx 23:00 h in the evening.
This graph is normal.

6. Obviously you lost your production October 23, which is probably the day, the electrician changed the meter.
But did you start Domoticz at December 16?

Conclusion.

I would definitely check if the inverter is connected (circuit breakers and connections) and if so, which Phase.
I would do this before deleting anything.

Hey @FireWizard!

Most of your assumptions are correct!
1. Yes I'm on stable. I can definitely switch to beta, but I'm afraid of bugs.

2. Yes I have a 3 Phase network, ANd Yes, the Solar inverter used to be connected to Delivery L3. But my conclusion is it isn't anymore.

3. Is it logical that in the last screenshot (where Delivery L1 and L2 are turned off) there is also no Wattage recorded than? I thought it should still show data even when turned off.

5. Yeah I noticed that too, But I do not understand why it is that way.. xD

6. Yeah it's actually teh 26th October, the Smartmeter display also showed a code or a change for that date, I believe indeed that's when the electrician came. Also since the 15th of December the gridowner has a disruption in their remote reading system.

As to your conclusion I opened up the fuse box and in fact did see that the Solar inverter is connected, also my energycompany and grid owner guys did get a return delivery from the solar panels. So it is connected however my Domoticz doesn't show the information, now there are just 4 cables coming out of the smart meter (3 black ones as Fase and 1 red one as 0 line) and 1 of the cables is connected to the solar inverter fuse.

I'm going to add/turn on Delivery L1 and Delivery L2 right now and see what happens although I'm wondering why there is no data value right now.

Thanks for your thorough look and explanantion! I hope we can figure this out!

OMG! I just checked it and there is a Wattage value for Delivery L1 (without tunring it on) ofcourse the sun has to be shining for the data (Most stupid I've felt since I don't know when..)

However next question!
Is there a way to combine the graphs? Liek either swap all the data that used to be on L3 in the database to L1 (and the same for the usages?)


EDIT:
Now I'm getting confused..
I'm getting data on Usage L1, L2 L3 and Delivery L1..
Isn't it weird to get data on All 3 of the usages and also the Delivery?
Or is Delivery L1 only viable if Usage L1 is 0Watt?
Or how should I interpret this?

Hi, @ThirstyThursten

To make a long story short.
Can we conclude that everything is working fine, but that the electrician has moved the connection from the Solar panel inverter from L3 to L1?

However next question!

I do not know this, as I have never tried it. Perhaps another users may know this, I suggest to raise this question in another topic and perhaps you will receive a useful answer.

You did not mention your location (of the Smart meter).

Normally you would expect that you either consume from the grid or you deliver to the grid.
So it is either consumption L1 or delivery L1.
However in Belgium the used protocol differs slightly from the protocol used in The Netherlands.
In Belgium you might see both consumption and delivery at the same time.

Hey @FireWizard!
Yeah I'm a Dutchy!
And Yeah I guess the Electrician changed the wires!
However I still notice usage on all three of the Usage L1, L2 and L3.. Is that weird?

And I will than perhaps open another topic.
Thanks for you quick replies today! Appreciate it!

Not at the moment, as it is already dark at this time of the year and I assume, you have divided your equipment equally over the 3 phases.
At the moment you have no production from your Solar Panels. Even during daytime in this time of the year it will be less than your phase L1 might consume.
