Tapo 304M randomly lost power for fraction of a second
Hi,
My Tapo 304M is connected to my router and NAS ,today it decided to lost power for a fraction of second , which caused my devices to crash.
All the firmware etc are up to date. there was no load on the extension as well, it is plugged in directly to wall socket
NAS load was around 40W and router load was around 30W

Same here.

I have 3 though and one went down. Has about 45w on 2 sockets, and 4w on another.
What might be worthwhile noting, is according to my home assistant logs, from 4 hours prior to its lost power, it kept disconnecting from the 'cloud connection'... with an ever-increasing frequency, and towards the end, an ever-increasing amount of time spent disconnected.
I've two theories as a result;
- Something was coming down from the cloud telling them to reset their connection. Or..
- The disconnections, regardless of cause, are reflective of, or related to, something crashing on the strip itself. Which it eventually resolves with a full reboot.

@leo1543 this is exactly what I saw in my home assistant logs as well
Many disconnect and reconnect state flapping from cloud connection and all the plugs also flapping from unavailable to on , eventually it did a full reset.
Happened around 14:30 BST April 30
Strange indeed!

Since you're using Home Assistant to manage the smart plug, it's worth checking whether the problem is caused by HA, as we have seen similar reports before. For more details, you may contact our support team for further assistance. Contact Technical Support
By the way, just in case you didn't know, Home Assistant isn't a supported third-party by Tapo. Managing Tapo devices through unofficial channels may lead to abnormalities we can't explain.

Suspect 'manage' is doing a lot of work there. My Home Assistant does nothing with the strips other than monitor them for power consumption data. Which is to say, it is poll-only. Though I don't know what you expect to check - there is nothing my end configured to simunateously disable all sockets on the strip temporarily. And similarly, no 'software function' exposed via the plug that'd allow an extremely quick change from On>Off>On.
Furthermore, realistically, it is TP-Links protocol. Is it reasonable that something that interacted via said protocol would be able to crash the strip via polling? Or otherwise inadvertedly cause an extremely brief loss of power delivery? I think not. Even a crash shouldn't interrupt delivery I'd have hoped.
Perhaps the firmware should be updated to support sending logs out via syslog? Then everyone could be sure.

It’s not uncommon for frequent polling from Home Assistant to cause devices to go offline or crash. Some users have also noticed that HA occasionally reports incorrect status — for example, showing a plug as off or unresponsive when it’s actually still powered on and functioning normally.
If you’d like to understand the exact cause behind this specific incident, you’ll need to contact our support team. And if you can confirm that the issue isn’t related to HA, for instance, if it persists even after unlinking HA, that would be very helpful information to share with them.
By the way, are you certain that the power strip lost power? Or is that based on logs from Home Assistant?
