From my support ticket with TP-Link, they have released an updated firmware for the P110 - 1.3.4 Build 250520 Rel.171612

I am in the process of applying this to most, but not all, of my P110 v1.0 hardware devices to check it. If it works, then I'll do the remaining ones.

If not, then I will get the flash log and send that backto TP-Link.

Hello,

Did you send us all your P110 Mac address ?

  @jeepcook 

I am working through the problem with one specific device, which has the problem (almost) all the time.

I applied the new firmware to all 7 of my devices in the end, although it's annoying that on some devices when it resets that is enough for power to blip and take the device powered offline, whereas on others it blips without dropping power to the plugged in device.

The new firmware (1.3.4 Build 250520 Rel.171612) makes no difference - the very next time I turned that device on, it lost its configuration and I had to set it up again via the Tapo App.

I have shared the flashlog file from the P110 with TP-Link technical support for them to continue to investigate.

  @Paul362 

So there are real problems. They have to stop the broadcast of this firmaware !!! 

  @Paul362 

Fort information, in my side it's easy to reproduce the bug (plug reset) when the plug is in 2 automations.

  @jeepcook 

Mine is the most basic use, with no automation, no timers, no schedules, no nothing.

I'm mostly just using the P110 to measure energy consumption for certain key devices.

I power the plug on, use the device powered by it for a few minutes, then I power the plug off.

With that basic use case, there is a random chance that when I power the plug on it has lost it's configuration.

This has only happened since upgrading to the newer firmware release.

Edit: I had a slightly different type of error today. Turned plug on okay, used device okay, turned plug off and at that point it reset and lost configuration with amber/green flashing lights.

Also, TP-Link technical support have explicitly asked if I use Home Assistant. I do, but noting that is a poll and read only system with no automation outside reading the energy data to populate the Home Assistant Energy Overview screen, so I can see where my energy usage is occurring. But I thought I'd highlight they wanted to know if HA was in use.

  @Paul362 

Ok so we have all possible cases.... I think they clearly didn't do a complete validation for this update.

It's disappointing because my project is (or was?) to automate everything in my house with the Tapo ecosystem.

TP-Link technical support has analysed my flashlog file and has provided another newer firmware to see if that improves or fixes things.

So in summary, firmware wise

• 1.3.1 Build 240621 Rel.162048 - older firmware that worked perfectly fine
• 1.3.4 Build 250403 Rel.150504 - introduced the problems and stability issues
• 1.3.4 Build 250520 Rel.171612 - problems still persist
• 1.3.4 Build 250523 Rel.181305 - currently testing problems still persist

Edit: This latest firmware, whilst improving things a little, still has issues.

When turning the device off via the button on the left, it doesn't seem to work. Wait a few seconds, press the button again, and sometimes it works, but sometimes it resets the smart plug and you lose configuration and have to set up as a new device in the Tapo App again.

  @Paul362 

I can confirm, some of my plugs are keep flashing so I had to pair them again and now automations are not working with new firmware and all data is gone

  @SugarBaby 

I don't know if these newer firmwares are publicly released or not.

If not, then you can log a support call with TP-Link and link it back to this thread, so they can see you're impacted like others are.

Hopefully they'll get to the bottom of these problems and then roll out a proper fixed firmware for all customers.
