I have both the devices T310 and T315 connected to the Tapo Hub H200. The hub is connected to my router through the wired ethernet port. The problem is that when i connect to the app through some other wifi or mobile data the T310 does not refresh . The T315 doesn't have such a problem.

  @CTX21 Yep same issue! Just bought a new T310. No temperature updates when using mobile data, or different Wi-Fi network. 

Weirdly, if I toggle the temperature unit from Celsius to Fahrenheit and vice versa. It forces a refresh. 

Another observation. Google Home seems to be refreshing live data. Although in between glitching out, between the correct data and what's stuck in the App. 

  @nilava Another thing to note- In the app if you trace the graph in history, you can see the latest data. But the top banner is not updated ever if you access it remotely., switching F and C refreshes but will never update after that automatically. I think their app is bogus and the worst part is they dont listen. i opened a ticket also which is of no use.

Now i have 3 sensors , one is T315, and i dont even look at them in app as i dont trust the data. what a waste of money. Tapo has become complacent and deaf.

I would appreciate any assistance you can provide. From what I understand, this seems to be a minor software glitch that could likely be resolved through a firmware update. Otherwise, the T310 devices are essentially bricked, as none of the smart actions are functioning.

Please let me know if you need any logs or additional details. I’m a big fan of TP-Link products and have heavily invested in the Omada line, which is why I decided to also go with Tapo products.

Yes, I’m experiencing the same issue. I believe a recent firmware update for the hub may be the root cause. Interestingly, when I connect the hub to Alexa via the Matter bridge, the temperature sensor works flawlessly. Although Humidity Reading is lost.

I appreciate your response, but I’d like to firmly clarify a few key points:

1. The issue is not network-related. I have thoroughly tested the T310 sensors under multiple network conditions:

   • Different ISPs (including a mobile hotspot and a dedicated leased line).

   • Full router resets and fresh configurations.

   • Separate SSIDs and isolated networks.

   • Disabling IPv6 and using just IPv4

   • All routers used are TP-Link ranging from consumer to enterprise-grade Omada series devices under SMB deployment.

2. The T310 is the only device failing. I currently have over 50 smart devices operating seamlessly in my home across Wi-Fi, Zigbee, and Matter. This includes devices from Tapo, Aqara, and competitors. None exhibit the issues I’m seeing with the T310.

3. The hub and sensor connect, but Smart Actions fail. Additionally, I noticed the T310 temperature readings pass correctly to Alexa when connected via Matter—but humidity data is lost and Smart Actions don’t trigger at all. This suggests the issue is not connectivity, but a firmware-level glitch or incompatibility in the Tapo ecosystem itself.

4. Complete factory resets of both the hub and sensors have been done. The issue persists across all configurations.

This is not a case of “common cloud disconnection” or a random coincidence. It’s a reproducible failure across multiple environments using TP-Link infrastructure.

Please escalate this to your firmware/engineering team. I am happy to provide logs, firmware versions, or conduct additional testing. But dismissing this as a general connectivity issue does not align with the facts.

Thank you
