Hi, just had a scare, as my Aqara home security went off due to a less than 4 month old Aqara smoke detector reported smoke in my livingroom. Since I’m currently away on business, I called my good friend and neighbour who rushed home from work to check it out finding absolutely NOTHING wrong.
So my question is if others in here have had same experience as me (hope I’m just unlucky), but if others have had the same we need an update otherwise the products is not helping anything. 
I’ve seen a few people mention false alarms with the Aqara smoke detector, so you’re definitely not alone. The good news is that in many cases it’s linked to things like steam, humidity, or even aerosols rather than a real fault. A quick self-test and checking the battery often helps, and Aqara support has been responsive if a unit turns out to be defective.
I’d see it as the detector being “extra sensitive,” which is better than the opposite. Still, it’s worth keeping an eye on it and maybe contacting Aqara if it happens again. Most users report stable performance once the environment is ideal, so hopefully this was just a one-off and your system will keep you safe without further scares.
It’s placed at my new house we have not really moved into yet, and the humidity is similar to outside so around 60% and temp is like 25-27C
The strange thing is the log shows something for like 5 min going up and down and to 0 and then back up a little and then nothing more…
If you’re currently renovating or painting, I strongly recommend removing the smoke detectors and putting them away in a safe, clean place. Once you’re finished painting and renovating, wait about another week and then install them. Believe me, I speak from experience 
You should also keep the minimum distance to the walls so that the sensor can “breathe” freely
Thx but everything is done and has been done since New Years so that’s not the reason. There is plenty of distance as it almost in the middle of the ceiling 
Looks like there is something wrong with your smoke sensor, may I have your Aqara account, so that the developer can check?
Oh yes… you’re definitely not alone!
I’ve had my fair share of false alarms too — and of course, they love to strike when I’m on a business trip, in the middle of the night. My wife is… let’s just say… not the biggest fan of Aqara smoke detectors anymore 
I’ve actually removed a few of them. Turns out they don’t like outdoor air (too many particles) — and definitely hate bathroom steam.
One trick that sometimes helped: blowing the sensor clean. But to be honest, that’s not exactly a long-term fix.
So, no solution here either — just solidarity.
We’re in this smoky mystery together.

Hi Naomi
I wrote support yesterday so I’m sure someone will get back to me fast as you always do 
Sound like we have same type of wife 
and yes I’m sure they will be sending an update to the smoke alarms soon or mine are going down until they do
Ok, please let me know if you need my help
Today mine on the Living room is having the same issue. It triggered 2 hours ago to 0.11 or 0.125. I blew up some air on it, and it went to 0. Now again, the same issue.
It is a lovely sunny spring day today and not that humid. The other one on the kitchen like 4/5 meters away (open space) reports 0.
Same multiple false alarms, it’s going crazy 
pretty annoying, looks like you have to add them to the weekly house cleaning schedule 
Same experience, false alarms all the time, no moisture, no dust, just random triggers at random times. The device is completely unusable. There is no such thing as false alarms are better than missing a real alarm. If a device triggers false alarms the device will be shutdown or ignored. Or Aqara releases a firmware update to allow to select a higher threshold or this device is garbage. The only solution I see to not waste the money on it is to connect it one day to the Home Assistant and define myself the alarm trigger threshold.
Personally, I have three detectors and I’ve never had any issues with them. They have always worked properly at the right time without any false alarms. Something I often see recommended is to place the detector outside for a while and then bring it back inside. However, I strongly suggest contacting customer support by email if this is the only detector in your home.
I had the same issue with 2 of my 15 smokedetectors. I suspect it could be dust or spiderwebs. I will try to change their location
Mine failed again 2 days ago when I was sitting on my couch and cleaned it like 2 weeks ago so have to send it back as clearly it’s faulty and support agreed
