sonoff pow rebooting every hour

[Reinhartd]

Hello!

yesterday i have posted the problem with TODAY_POWER, and this problem is the reason.
I have 2 sonoff pow and 2 sonoff Switches.

• sonoff Switch with V 2.0.10 NTP is OK, and no rebooting
• sonoff pow with 2.0.10 NTP is NOT OK, and rebooting every hour.

when i disable SONOFF_POW and activate SONOFF ( on the sonoff_pow module in user_config.h ), then sync with NTP is OK and no reboot (but i have no data from energy).
//#define MODULE SONOFF_POW

here is the syslog with the reboot situation

What happens when all logging is set to 0? (seriallog, weblog and syslog).

[Reinhartd]

i have found a solution!
the init time of first WIFI connection is very slow, if 9 seconds is too low then can the NTP init not runing on reboot!
i have changed this line and NTP is now running on my POWs.

if ((rtcTime.Second > 57) && !ntpsync) {

here is the log, NTP is now running on my POW after rebooting!

... and no reboot when change the hour, TODAY_POWER is now ok!

Do you think this method is ok?

[arendst]

It's a nice workaround.

In version 2.0.11 I've updated NTP sync to wait for a wifi connection. You might give it a try.

[Reinhartd]

Thank you for your good work an for the new Version, i have tested it in the Night on 2 devices!
in 2.0.11 the reboot Situation is very better, reboot ist only 10 - 12 hours. I have all logs disabled.
When the device is rebooting, the TODAY_POWER is saved, it's very good.
When the power consume is 0, then the PERIOD_POWER is always 0, is this correct? When power consume is coming, then the PERIOD_POWER is increase.

The calibration of HLW working fine and NTP sync is 100% ok!

hm, my WIFI Router is rebooting ervery day at 07:00, is this a Problem when the pow lost the Connection?
I disable the automatic Wlan reboot and test it again!

[arendst]

PERIOD_POWER is the power consumption between two teleperiod results. As you noticed it's 0 when no power has been consumed. Note that it's resolution is Wh so with a small teleperiod you won't see any value either.

You router reboot might well be the cause of sonoff reboot. I will look into it and see if a more gracefull recovery is possible.

[Reinhartd]

i have diasbled the automatic router reboot and my sonoff pow ist now running 27 hours an never reboot with 2.0.11! All functions now working correct!
Thank you for your good Support!
