Nightly outage of all data between 02:28 and 03:38

Hi All!

First time poster, but I have a fairly comprehensive setup based around an Emonpi monitoring Solar, battery & ASHP. Absolutely love the product and would be lost without it :slight_smile:

One thing which has me puzzled however is that there seems to be a period between 02:28 & 03:38 every night when the Pi is offline.

I have looked into the logs and it seems that there isn’t anything of interest in there… An excerpt from last night just shows the following around that time:
2022-01-10 02:17:50.489|WARN|emoncms_mqtt.php|Not connected, retrying connection
2022-01-10 02:17:50.568|WARN|emoncms_mqtt.php|Connecting to MQTT server: Connection Accepted.: code: 0

Does anyone here have any ideas as to what this may be, or how I may be able to debug what’s going on / been going on at all?

Many thanks!

Bump, although this time although the start time of the outage was consistent the end time was slightly earlier:

Can you paste in the system information from your Admin → System Information page?

Sure…

So it looks like your Pi rebooted at (11:06 - 7:51) 3:15AM?
Are you losing power to it?

Do you have SSH access? If so, can you check the contents of /var/log/syslog around the relevant time?

Probably not relevant for you, but I had a related problem where a subset of my data was always missing between midnight and about 1:00 am. It took a while to track down, but in my case the data was being captured from a “smart” hybrid inverter through mqtt. Apparently this inverter goes offline for about 15 minutes at midnight while it checks for - and installs - any firmware updates!

Thanks for the replies :slight_smile:

I should have ssh, I’ll try at lunch and pull any relevant logs. I don’t think there’s any reason it could lose power. The weird thing is that it is in the cupboard with our ashp controllers and it occurs nightly when the domestic hot water is heating up. Not sure if this is linked?

I did think it was more likely to be one of the peripheral devices sending days in but then as greebo noticed I saw the actual pi was logging a reboot.

Apologies for the massive file dump, I tried to attach but couldn’t attach a text file.
Looks like the pi reboots at the start time of the outage (~02:18)

I wonder why it then takes > 1 hour to start logging data again? This includes the sensors directly attached to the pi (I have 3 heat sensors attached which don’t log anything in the ‘outage’ period)

Can you see any clues in the log?

Thanks!

I think this is the most interesting part:

Given that the below log entry seems to occur every 5 minutes, and last occurred at 2:15, the power must have dropped between 2:15 and 2:17

Going back to your previously posted log:

I’m not sure what is happening between 2:19 and 3:43 - but not much!
Is it waiting for timesync before doing anything else? It does seem to “come alive” once timesync has succeeded.

I think your main goal will be to avoid the power outage in the first place instead of trying to work out why it takes so long to come back. Obviously the cause of the delayed start would be good to know as well, but the root cause is (probable) loss of power around 2:17AM.

Did your Internet router or Access Point go down as well between 2:17 and 3:43? (just wondering about the delay in achieving time sync)

Yes I do agree about the avoidance of the outage being better than trying to fix the subsequent symptoms. I may try changing the power source to another socket to see if that makes any difference at all.

What I don’t understand however is if we are seeing the logs of a shutdown event at approx 02:17, and the cause of shutdown is power loss, how is the pi able to have enough juice to log a controlled shutdown? Does the pi have a mini UPS (capacitor?) built into it for events like this?

We’re looking at two different logs from 2 days, and the one from the 12th I can’t see the full picture :slight_smile: I’m not sure if the power loss and the controlled shutdown are related. It could be that the pi did a controlled shutdown after booting up following a power loss because the file system needed corrections when fsck ran. That can trigger an automatic “controlled” shutdown - after the fact.
Just a possible scenario - the pi lost power, restarted, found (and corrected) file system errors on the rootfs, then triggered a controlled shutdown/restart. That is just a guess though because I can’t see the whole log from the 12th.

The log from the 13th didn’t show any signs of a controlled shutdown.

The Pi doesn’t have a real-time clock so you can’t rely on the timestamps at all until the network has come up and the time has been synced.

The “Reached target Shutdown” messages are referring to a systemd user instance (pid 553, not pid 1), so it doesn’t refer to the system itself shutting down. It looks like a user logout more than anything else. Odd.

It does look very much like a power outage. I would suggest you find a teenager who is going to be up at 3am anyway to log in to the thing and see what happens around that time :grinning_face_with_smiling_eyes:

What power supply are you using for the Pi? Is anything else plugged into the USB ports?
