TP-Link Tapo L530 offline in Google Home - Works fine in Tapo App
Hello,
I am encountering an issue with the my Tapo L530B. Previously this was working no issues with Google Home. On the 1st of January, 2026 (I am based in Melbourne, Australia), I tried to use voice commands in the morning to turn the light on and Google home said it was offline. I spent hours clearing cache, deleting, adding and relinking with google home to no avail. I had no issues connecting it through the Tapo app so left it.
On Friday, the 2nd of January, 2026, I checked Google home in the morning and the light was available again and working with voice commands. Great, however this was short lived.
The next day, Saturday (3rd of January, 2026), the light was once again offline and unreachable in Google home but still working in the Tapo app. I purchased another Tapo L530B thinking it might be the globe but again the same issue with the brand new light. I can add it to Tapo, can add it to Google home through linking but it is always offline.
I have also tried another brands bulb and has no issues so this seems to be a Tapo/Google home issue and not a network one.
I will say I also have multiple Tapo smart plugs in the same Tapo account which can be linked to Google home and controlled via Google home and with my voice, no issues. It is just the bulbs that seem to be impacted.
Thank you in advance for any help.
To add to this, I have just checked the smart bulb while I am at work and it is now showing as offline. I tested it this morning before I left for the day and the globe was online and able to be controlled via the Tapo app but not via google home still.
As you can see the wifi signal is very strong so I am at a loss here as to what the issue might be. Like I said, was working no issues until a week ago and not it is unusable
Hi @Wayne-TP
I did a hard reset and the device is connecting fine within the Tapo app but still not connecting with Google Home. I can link Tapo but the bulb is offline as soon as it is added. Furthermore the name of the bulb from the Tapo app is different to what is coming through on Google Home. In Tapo it is called Office Light but in Google Home it is trying to add "Smart Bulb".
There appears to be some kind of syncing error between this bulb and the tapo servers which was not present prior to January 1st, 2026 as I can confirm that when I am on mobile data I am unable to access the bulb as it appears offline
I have tried the instructions about changing the DNS server however the problem persists.
As I said previously, I would understand if all my Tapo devices could not connect to the Cloud servers but it is just these bulbs. If there was an issue with my network, the smart plugs should not be able to connect to the server either.
