DSMR integrations stops irregularly since Nov 15 2022

[jan-gerard]

The problem

As of November 15 (2022) my DSMR integration "DSMR Slimme Meter" (installed as a standard integration though HA) stops reporting. When I restart HA, it works fine again for some time. It happened on Nov 15, Nov 18, Nov 20, Nov 30. Nothing was changed physically. The energy meter is connected with a P1 to USB cable (from SmartMeterDashboard.nl) since almost 2 years without problems. It is connected to a Raspberry Pie 4 running Home Assistant OS. I'd love to provide extra information, but where to find that kind of logging? And where can I find a history of core- and integration-updates? If it happens again, what can I do to capture some logging before resetting the system?

What version of Home Assistant Core has the issue?

2022.11.5

What was the last working version of Home Assistant Core?

2022.11.1

What type of installation are you running?

Home Assistant OS

My dsmr integration also stopped working yesterday. Is there any way to analyse this?

Same here. Works fine after restart, but stops and freezes at some point. This can be found in the logs `Logger: dsmr_parser.clients.protocol Source: /usr/local/lib/python3.10/site-packages/dsmr_parser/clients/protocol.py:141 First occurred: 07:25:00 (21 occurrences) Last logged: 07:39:45

I am experiencing a similar issue. I am using P1 > Wifi and everything works fine and after a couple of hours is stop updating the sensors in HA while I can see that the P1 module is still working fine and when I enable debug logging I can see the datagrams showing up in the logs. Until a couple of days ago I was using this P1>Wifi module with Domoticz and it ran for years without problems. But somehow with this integration it stops after a while.

Any idea what I can do to help debug this? (I am kinda new to HA though).

Here it is the same. Sometimes after a reboot host it works for a short while. DSMR integration worked flawlessly for a long time and all of a sudden it becomes unreliable. For me I switched to the HomeWizard integration for now to keep the Energy dashboard alive. I never wanted the (used HomeWizard as some kind of a backup) as DSMR is directly connected to P1 via an USB cable, which in my opinion should be more reliable. Anyways: I hope this issue gets solved really quickly. MY feeling is that this is caused by some dependency update along the way.

I am currently running

Home Assistant 2023.1.4 Supervisor 2022.12.1 Operating System 9.4 Frontend 20230110.0 - latest

I created an AppDaemon script that monitors the updating of the sensors in HA and if the last update is longer than the polling interval I restart the P1 module connected to my meter. When the module restarts the integration picks it up again within a minute. I can see that this disconnect/stalling happens 1 or 2 times a day. At least I have a way now to not loose any significant data. But it is annoying.

I also exprience the same issue. I am using a P1 > USB cable. After every restart of HA the monitor starts working, but after a few hours it stops working again. I am using this tool to read my energy consumption and now i have to manual read the meters. Is there maybe a workaround or is there already someone looking in this issue?

[dxfoxd]

Same here. Side symptoms, not showing Gas consumption and missing electricity values such as sensor.current_phase_l1, sensor.current_phase_l2, sensor.current_phase_l3, sensor.long_power_failure_count, etc. Power consumption is working though. Using a P1>USB cable in RPi4.

[SchulieBug]

Same here, since yesterday afternoon it stops. I restarted DSMR, checked the P1 itself and it runs fine. Within Domoticz is also shows up without any issue!

[TieskeC]

Same here!! I see the same issue. I had this before and created a Node red automation to restart however.. i check if any of the 3 phases reports < 100 VAC.. however.. the values froze so my node red check does not work.

@dannybloe : ==> I get what you did, but since I am a software noob (at least noob-ish) i would kindly like to know how you approached the re-start. preferably via node red.

Thus far i created an edit-poll-state-node that subsequently gets smooth(ed) and where i return the standard deviation. I calculate this over 5 values (which when frozen is 0). However, what node is next...

[RF197]

Same here. I have to restart the integration every few days. Sometimes it goes for a week, sometimes less than a day

[CoenWarmer]

Same here. Worked fine for a few days, suddenly stopped reporting. Any idea @frenck?
