PIN submission

[veitw]

Hi @alengwenus,

thank you very much for your effort. The sml component works great for me.

Do you plan to add support for sending a PIN to the meter?

I use a Holley DTZ541, unfortunately it emits only very basic OBIS data unless a PIN is submitted:

• active power
• inbound power meter tariff 1
• inbound power meter tariff 2
• inbound power meter combined
• outbound power meter

But after a PIN is supplied, it will send these additional values:

• voltage L1
• voltage L2
• voltage L3
• current L1
• current L2
• current L3
• voltage phase angle L2:L1
• voltage phase angle L3:L2
• voltage phase angle L1:L3
• current phase angle L2:L1
• current phase angle L3:L2
• current phase angle L1:L3
• mains frequency

Best regards, // Veit

All energy meters I know have a button or can be flashed using a torch to enter the PIN. Doesn't that work with your energy meter?

It has one, it also shows the extended values on the display screen after entering the PIN.

But after a minute or so, it returns to the basic values and one has to re-enter the PIN. Thus the question whether you plan extend the component to submit the PIN to the smart meter.

I have checked the manual of your meter. There is the possibility to disable the pin retrieval. With that option you should be able to continuously see all values.

This is what I had already configured:

• Pin off
• Info on

It gave me only the information described above.

@BMOD89: Do you have a real manual for this device? So far I only found some very basic guides, mostly like quick start guides for the menu.

I guess it is the same manual: https://www.holleytech.de/wp-content/uploads/2021/03/Benutzerhandbuch_mME-DTZ541_V2.0.pdf

I have a different meter, but the principle (menu and so on) is similar and for my meter it is sufficient to set the values as you just described.

I am not 100% sure but I think the optical interface is only unidirectional. So you cannot set a pin via the optical interface. At least I haven't read about that possibility yet...

@BMOD89: Thank you very much. From this document I learned that, differing from the quick start guide, the power meter does not have two but three different modes for the D0 interface; "reduced", "complete" and "manufacturer-specific" data set -- and the additional information I'd like to monitor, which was said to be available in the quick start guide, is only transmitted in the manufacturer-specific mode.

Regarding to the manual, this mode can be enabled via the "rear interface" -- whatever that exactly means, as it is nowhere mentioned again in the manual...

It seems that "rear interface" refers to the RS485 port, which is in fact on the front of this power meter, but not accessible to the consumer. :(
