[aravindjaimon]

The problem

I have 3 P110 plugs available. 2 of them are connected to grid and 1 is connected to battery (always online). The two plugs that are connected to grid goes offline when electricity is gone. Once it comes online, The functionalities are working fine. But the following items are unavailable.

Hi @aravindjaimon, is the log file you uploaded from an actual instance of the grid being disconnected? When the grid gets disconnected does the connection to the internet also get interrupted?

[applegeeks]

Happened to me today. What worked for me was to completely power off the smart plug from the mains. Power it back on and then reload the integration in HA.

Same issue for my P110 devices. I tried a workaround that worked for P100 devices (turn off LED in Tapo app and turn on again, then power cycle device). But that workaround did not work for this issue.

Hello, I have same issue too since today for P100 / P110 / P115

Hi, I have uploaded 3 log files where two are the ones that become unavailable.

When the grid is gone, the Internet is still working. All the other peripherals are connected to UPS which comes out through the Battery our plug. Ill recreate the issue once again and share the log file here.

It seems from the previous log that when the devices came back online they initially raised a lot of errors because they were not connected to the cloud and not able to get the device time. That caused a lot of the modules to get disabled. Would they definitely have had full connectivity to the internet as soon as they turned on?

my P110's doesn't work in integration anymore. Although I see them (and can work with them) via stock app

I also have the same issue from this topic, once a P110 gets disconneted for a certain time from the mains power, when they get power again i have to reload the device integration.

I have 3 P110 and today all of then failed the connectivity with the cloud, i have a lot more devices from tuya and those worked ok without problems.

For the last two days (approx) I have the same issue with 4x P110.

[zqnikals]

yeah. after each power outage i need to rebbot HA to get current consumption back

[imsuperimposed]

None of my P110s are connecting I have 5 have rebooted HA, the integration and power cycles the unit, this started three days ago.

[aravindjaimon]

Got a work around for the same by making the 2.4Ghz wifi channel to constant. Mine was set to Auto now moved to channel 6. Since today once all devices including router is restarted, Things started working normaly. But there can be a fix inside the integration as well.

This is not related to this issue. Please upgrade to 2024.7.3 and power cycle the devices to clear this issue.

[aravindjaimon]

@sdb9696 I got why its not working for me, I am using a TPLink mesh system in my home, I am not experiencing any issue once the mesh is turned off. Is there any patch that can be done to the system for this?

[sdb9696]

So I'm working on a PR in the python-kasa library that could fix this. Any chance you could reach out to me on discord so we can test it with your setup? My username is sdb9696.

[sdb9696]

This issue is fixed in the latest beta 2024.8.0.b0. Please feel free to test this out on the beta and provide any feedback in the homeassistant discord beta channel. (Make sure you have backups enabled in case you need to rollback).
