Should the red blinks be there?

Hi
I did happen to see red blink on my Pow-K+ as on https://www.youtube.com/shorts/YlMpvfMDF2Q
Seems to be working OK but I needed to ask ;-)

Interesting!
No, there should be no red blink. Normally, there should be a red indicator or an error message shown if there are is red blinking.

As indicated in the Firmware v2.2. User Manual, a single red blink indicates that the meter received invalid data:

I propose you take a peek "under the hood" by running a Telnet debug: https://www.amsleser.no/module/ets_blog/blog?id_post=24

I did get Device is booting, please wait when disabling debug and now the red blinks are gone.
Maybe uptime (52 days) "overflow"?
Enclosing telnet log
telnet.log
There are some
No HAN data received last 30s, single blink

[ArnieO]

Interesting.
It was probably the reboot that fixed it, but the problem should not have been there in the first case. On Pow-K there is no cable issue, so it should not fail the reading in this way.

Uptime 52 days should certainly not give overflow.

Which version Pow-K hardware are you running? A screendump of your Info-page should provide the information I need to assess.

[rogerthn2019]

Reboot is known to fix a lot but shouldn't be needed?

[ArnieO]

OK, so this is a Pow-K that you bought from us?
If you still have the issue of "No HAN data received last 30s" after reboot (that should not be needed), I suspect an issue with your board - and would like to replace it.

Yes, Pow-K+ bought from you.
It has been replaced once, due to unexpected reboots by you 2023-03-30.
There are no "No HAN data received last 30s" right now.
Let's wait and see if it happen again, maybe after 49.7 days uptime.

[ArnieO]

OK, that is a good plan!

Found the bug, uptime (millis) rollover is the issue

[rogerthn2019]

I did happen to see red blinks again before the upgrade to v2.3.6, uptime +50 days.

Huh... "No HAN data received last 30s, single blink".
