Issue with P1 Smart Meter

Posted: Tuesday 12 February 2019 21:02

Hi All.

I have a Issue with a lot of CRC Failed messages.

Version: CURRENT: 4.10373 (BETA) and 4.9700 (Stable)
Platform: Raspbian on Raspberry Pi 3
Plugin/Hardware: Philips Hue
Description: Issue with P1 Smat Meter

I have tried the following, but unfortunately I still get CRC notifications
1) reset the hardware device in domoticz (delete / reboot / readd)
2) reset the hardware dongle it self
3) upgrade to last BETA.

Code: Select all

How is the data arriving into Domoticz? I mean, direct usb cable into the raspberry, via a serial to USB converter or via a raspberrry running ser2net for example?,
CRC errors can be caused by a bad cable, wrong serial settings, length of cable between p1 and usb device (interference ), usb power to your domoticz and faulty p1 on the meter

Things to try:
use a different means of getting the data in domoticz. ie. change cable, or try something like serial2net, triple check baudrate settings

Do you still have this problem? I had a new meter installed and now I have similar problems!

Hi,

You said:

I assume, that you had no problems with your old meter?
What is your baud rate? Should be 115.200 8N1.

Regards

I had no problem with my old meter. New one is L+G E360. I have baud rate at 115200. I see no option to set 8N1 somewhere. Running on Version: 2020.2.

Did you try to disable the "CRC message validation" in the settings of the P1 meter?

Thanks.

Now I am getting some values in. But I am still getting a lot of:

This is not the correct way to start with. CRC errors means that there are communication errors between the P1 port of the smart meter and Domoticz.
You can disable these, but that does not solve the cause of the CRC errors. If you hide these, it doesn't mean that they do not exist anymore.

Unfortunately the output interface of the smart meter are not the same for all types and brands.

You did not tell which type, you used before.
The probable cause might be the cable. For the Landis and Gyr E360 (and also the E350) a pull up resistor is required.

See: http://domoticx.com/p1-poort-slimme-meter-hardware/

See also this post: https://www.domoticz.com/forum/viewtopi ... yr#p231414
and: https://www.domoticz.com/forum/viewtopi ... yr#p228375

I think you should solve the issue and check, if there are changes between your old Smart meter and the Landis + Gyr E360.
And then you can re-enable the CRC setting again.

Of course you are right, but it might be a way (temporary) to tell if the message is then OK.
The option is there, so you might try to use it temporary. Why is the option there?

The first versions of the P1 Smart Meter protocol, such as DSMR 2.2, didn't contain a CRC check. So, if it happens, that you have an old meter, with a protocol prior to version DSMR 4.0 and you want to use Domoticz, you have to disable the CRC check.

This protocol itself, I cannot find at the website of Netbeheer Nederland, but if you are interested you can check:
http://read.pudn.com/downloads145/doc/6 ... l%20P1.pdf

Another reason, I cannot imagine.

The change that disabling the CRC check solves the problem is very small, so disabling is not recommended, as long as the protocol supports CRC.
Most of the smart meters do.

The old meter was a Kaifa SSMR5.0 MA304H4CNL. The cable I bought ready made.

Did you ever find the solution to E360 and CRC errors? I am having this same issue. Is the CRC calculated differently than in older protocol versions?

No, the protocol has not changed and the way the CRC is calculated has not changed either.

Did you check your cable?

Best regards

I dont think it is a cable since there is another user with the same setup and he also gets the same crc errors. More finding is that the E360 uses ESMR5.0 protocol and I wonder if that has a different crc checksum calculation.

Hello @bortek,

Please do not X-post your post.
That will probably not gain more attention, but create more irritation.

I will answer your question at: viewtopic.php?f=6&t=31593&start=20
