Shelly is frozen

[21-Jailbraik-21]

Hello, thanks for the script
I have 2 Shelly 1Plus PM running in Venus OS.
I've only been running the script for 2 days.
But today a Shelly is frozen in the VRM - the display shows 58 watts. But it's night :)

IP is the same ???

Dear @21-Jailbraik-21 , a possible issue with Shelly could be

• IP address , as @Halmand mentioned
• unstable WiFi connection
• Firmware update on Shelly

I noticed that the shellyPlus1PM values froze after an unstable WiFi connection. A resuming seems to fail as well after a shelly firmware update.
In both cases, a reboot of the VenusOS device solves the issue.

Best, Andreas

[21-Jailbraik-21]

OK thanks
It just happened again.
Have fixed IP addresses assigned.
Updates are current.
Will watch again.
Could you try a daily restart?

[Halmand]

my shelly runs 2 months no problem.
Wifi 2,4Ghz or 5Ghz many have problems with 5ghz

[21-Jailbraik-21]

All three run in the 2.4GHz range.
L2 froze again today.
I have 3 pieces: L1 / L2 / L3

make logging to debug and look the log

Unfortunately, L2 is offline again.
Yesterday what it L1.

Copied part of the log.
I hope you can help me.

[Halmand]

the Ip adress are Fixed and have no a second device withe same IP ???

[ThomasLohner]

This happens when the shelly is not available. For example i see this after shelly reboot. There's some error handling in the script but maybeI the loop somehow gives up after a couple of tries. Then the script is still running but not gathering data anymore.

[21-Jailbraik-21]

Hello, just wanted to give feedback.
It's been working for a week now with no problems.

The problem was probably with me: WLAN access point was activated. Since I got rid of it - no more problems.
