Temperature & Humidity Sensors repeatedly going offline with G350 – should I return them?
Hi everyone,
I’m looking for some advice regarding two Aqara Temperature & Humidity Sensors that keep going offline.
My setup
Everything was purchased less than a week ago:
- Aqara Camera Hub G350
- Aqara Camera G100
- Aqara Cube T1
- 2 × Aqara Temperature & Humidity Sensors
The setup is installed in a small studio, so distances are very short.
The G350 and G100 have been completely stable, and the Cube T1 paired with the G350 works reliably, including when triggering automations.
The problem only affects the two Temperature & Humidity Sensors.
The problem
Both temperature sensors repeatedly lose their connection and appear offline.
This happens even though:
- they are located less than 2 metres from the G350;
- I have replaced the original batteries with new ones;
- I have successfully removed/reset/re-paired the sensors;
- after pairing, they work normally for a while;
- then they eventually go offline again.
So far, changing batteries and re-pairing has not solved the problem.
What confuses me is that the Cube T1 remains connected to the same G350 without any apparent Zigbee reliability issue.
What I found while researching the issue
I searched Reddit and the Aqara Community and found several reports describing very similar behaviour with Aqara Temperature & Humidity Sensors, including with hubs other than the G350.
Reported symptoms include:
- Temperature & Humidity Sensors randomly going offline while other Aqara devices remain connected;
- sensors disconnecting despite being very close to the hub;
- replacing the battery not permanently solving the problem;
- sensors coming back after re-pairing or pressing the button, only to disconnect again later;
- reports of this behaviour going back several years and involving different Aqara hubs;
- similar reports still appearing in the Aqara Community in 2025–2026.
Because this behaviour appears to have been reported with several generations of Aqara hubs, I am wondering whether this is a recurring reliability issue with these particular Temperature & Humidity Sensors rather than something specific to the new G350.
My question
Has anyone experienced this specifically with the G350 + Aqara Temperature & Humidity Sensors?
More importantly, for people who experienced the same repeated disconnections with these sensors on other Aqara hubs: did you ever find a permanent solution?
Since all of this equipment is less than a week old and still within the return period, I need to decide whether it makes sense to keep troubleshooting or simply return the two temperature sensors and use a different model/technology instead.
If this is a known issue that has persisted across different Aqara hubs for years, I would rather return them now than repeatedly re-pair them or wait for a firmware fix that may never address the underlying problem.
Any long-term experience with these sensors would be particularly helpful.
Thanks.
