Kaifa crashing on entity generation unique_id

[TheDiverM]

Hi
I have just installed your nice little software, but on my kaifa 3 phase meter it say 0 volts on ams_voltage_l2, is this something in you module or is it something wrong in my meter?

im using this mbus module:

Thanks for using my software.
Your issue is not a problem. It's how the meter is programmed. I do not know the reasons to why it is so.
It's noted here in this document on page 3: https://www.nek.no/wp-content/uploads/2018/11/Kaifa-KFM_001.pdf

another issue, migth be that I use a pi3, but the software runs for about 1 hour, then stops, while measurement comes in it is a load of 1.4 to 1.9, when it stops measure, load drops to 0.1

is the pi 3 just to small or is there something else.

the pi that has the mbus adapter only runs the norwegian han sensor, nothing else.
last log entry

from log on rpi:

The unique_id error is known, but it will not stop homeassistant from working.
The socket.send() error might though.
I have the software running on a pi3 as well, without problems. (I also get the entity id error on the hourly package)

[TheDiverM]

for me this halts the entire homeassistant collection of data from the meter, only way to get it running again is to restart the PI.

im open to suggestions for how to fix this issue

[TheDiverM]

I found this line:

homeassistant.exceptions.HomeAssistantError: Entity id already exists: sensor.ams_active_power_import_none. Platform ams does not generate unique IDs

seems like system try to create the ID:
sensor.ams_active_power_import_none
but it already exists

another question, do you use 32bit or 64 bit version?

[turbokongen]

I am running:
/bin/bash: ELF 32-bit LSB executable, ARM, EABI5 version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux-armhf.so.3, for GNU/Linux 3.2.0, BuildID[sha1]=3e5e2847bbc51da2ab313bc53d4bdcff0faf2462, stripped
Please try the unique_id branch and see if that will fix it for you.

[turbokongen]

Make sure you use the latest code. Just published another fix for this.

now Im running on 32 bit hassio for rpi3 (was running on 64 bit when errors occured)
and now it seems like all runs fine, and no errors in the logs.
so maybe put something in readme about error in 64bit version..., ill give another feedback tomorrow if test runs fine all nigth

edit: still running stable, so I guess, 32 bit was the trick
