Model: Tapo L630  
Hardware Version: V1
Firmware Version: 1.1.2

Hello,

This is really critical. I bought a pack of 4 x TP Link L630 light bulbs. I paired them using the Tapo App on iOS, I updated their firmware. 

It's been now 3 weeks, and it's the 4th time I have to re-pair them. After a few days they appear as offline in the app and when I turn on the lights, when they become offline in the app and the wi-fi connection shows up as unstable, I cannot connect back. And I have to restart the pairing process. I have tried soft reset, factory reset. Nothing works. What's going on? Is it because my wi-fi router doesn't have a stable IP address. Or what is it? How can we diagnose the issue?

When the smart bulb undergoes a soft reset, the WiFi settings will be cleared while retaining all other settings. 

 

In cases where the bulb is reset due to an unstable power supply, we are planning to update the reset method, which should improve this situation. We are also offering community users an early opportunity to try it out. If you're interested, please refer to the details below.

Did you use the physical switch to control the light bulb, or with the Tapo app? Is it correct that smart bulb's default WiFi (Tapo Smart Bulb XXXX) reappears when it shows offline in the app?

This time it was the light switch.
 

Yes. The 4 different networks corresponding to the 4 different light bulbs reappear. And I have to redo the process again. 
 

Is it because I have dynamic ip at my wifi, or what is it? How can I even diagnose this, i ve looked thru the manual.
 

any advice?

Switching the light bulb from the power source has a risk of resetting the device due to grid fluctuation when the power is restored. And it is your case.

 

What are the hardware version of your Tapo L630s? Are they all V1?

Hello,

 

I have similar problem TAPO L630 (firmware 1.1.2 build 240829).
7 bulbes are wired behind a power light switch.
When the power is off for a long time, the bulbes loose wifi configuration.

I do not think they reset because the last color is still there when power is on. But the bulbes are not available in the Tapo App anymore.

 

Could it be something similare or related ?

 

REGARDS,

many thanks for your reply.

I noticed the default wifi of the bulbe is not available. Does that confirm your diagnostic of reset ?

 

The status is , when I power up the bulbes:

- they keep the last color

- they are not available in the app

- they are not showing there internal wifi network for settings.

 

regards,

Well, now it doesn't look like a reset issue in this case. Did you check your router's client list to confirm whether the smart bulbs are still connected to WiFi? 

 

Ensure your phone is connected to the same WiFi network as the smart bulbs when checking the Tapo app. Disable VPN if any. Try to reload the app homepage, or force-close and re-open the app, double-check whether the smart bulbs appear in the app under local network.
