I use separate 2.4ghz set to 20mhz bandwidth. always use channels 1,6 or 11 depending on neighbors.
mine disconnected today.
I wanted to assign a static DHCP and see several unknown devices in my router. how can I find the MAC address of the meter?

If you have the dashboard configured - bring up the “Show monitor information” window. The device serial is the MAC.

Hi everyone,
@IPMI @Zenit I have configured your place to receive 3.6.2. I’d greatly appreciate it if you can provide us with your feedback after the monitor is updated to the new firmware.
@uncle_t You can find the MAC address in the monitor’s serial number as @tadawson mentioned. And if you don’t mind, please feel free to reach out to us via support as I mentioned above. I’m happy to enable for your Place ID to get 3.6.2 if you would like to test it.
@tadawson Thank you so much again for providing the info for our friends in the community.
And I’d like to say thank you a lot again for everyone here who help providing your valuable information to help us fix the issue. Especially those who enrolled for testing the FW 3.6.2.
Please feel free to let me know your feedback on the FW 3.6.2.
If it works well for most users, I will bring this up to our team, so we can roll out the new firmware globally.
Thanks and hope you’ll have a nice weekend guys!

@Tai_AirGradient I’m afraid regarding my O-1PST the issue was a “PEBKAC”: in my paranoia I had set that particular outdoor SSID on a timed On/Off shedule! So the monitor “disappearing” was quite natural I’m afraid.
I’m happy to retain both monitors on 3.6.2 and see what happens.
Sorry for the false data point

Both my monitors are on 3.6.2 and everything is fine, last week the Wi-Fi disconnection issue didn’t happen anymore.
Thank you and have a nice weekend!

Hi there! I just submitted the support ticket. The monitor which dropped offline the last time has dropped offline again.
Here’s some more information to help.
1: Model is the AirGradient ONE. Note that I have 3x AirGradient ONE Devices and 1x AirGradient Open Air devices on the same network and in the same location. Only one device is experiencing issues.
2 and 3: OLED Screen shows Wi-Fi is disconnected. The left-most LED is lit solid red. My UniFi Network reports the monitor is simply dropping off of the Wi-Fi. The monitor itself continues to report and measure data locally via the Screen and LEDs.
4: My Network uses Ubiquiti UniFi UXG-Pro (Gateway), a USW-Enterprise-24 PoE Switch, has 3x U6-Enterprise-IW and 1x U6-Enterprise Access Points.
5: Here’s the configuration of a monitor which is working, and a monitor which is dropping offline:
Malfunctioning Monitor
country "US"
pmStandard "us-aqi"
ledBarMode "co2"
abcDays 180
tvocLearningOffset 12

Good Monitor:

For safe measure, here is a third monitor which is also working properly:
country "US"
pmStandard "us-aqi"
ledBarMode "co2"
abcDays 180
tvocLearningOffset 12
noxLearningOffset 12
mqttBrokerUrl ""
temperatureUnit "f"
configurationControl "local"
postDataToAirGradient true
ledBarBrightness 100
displayBrightness 100
offlineMode false
monitorDisplayCompensatedValues false
disableCloudConnection false
model "I-9PSL-DE"
httpDomain ""
extendedPmMeasures false
Curiously, one of the “Good” monitors reports Thailand as the Country/Region rather than United States. I’m in the United States.
6: My network broadcasts two separate SSIDs, a 2.4/5Ghz combined network on WPA2, and a WPA3-SAE network broadcasting on 2.4Ghz, 5Ghz, and 6Ghz. The monitors are connecting to the WPA3-SAE Network.
7: Four access points, which are all hardwired to the network. No wireless meshing is in use. However I run protocols such as WPA3-SAE Fast Roaming, and 802.11R/802.11K/802.11V on the access points.
The wireless signal for my monitors ranges from -49dB to -60dB. The problematic monitor will have a different RSSI depending on which access point it selects.
8: Everything is DHCP for the monitors.
9: Yes
10: Yes. Home Assistant
11: Did not try a downgrade. Let’s try the latest firmware.

Hi guys! Hope you all had a great weekend.
@IPMI Please don’t worry at all! If you need any help, please just let me know.
@gianfranco.bottini Many thanks for the feedback. I feel encouraged to hear it. Looks like we will be able to roll out the new firmware globally soon!
@Smith6612 All set! No actions needed on your side. You should get the new firmware in a few hours. Or you can force the monitors to detect the new firmware quickly by just power cycling them. Feel free to reach out to me if there’s any issue.
Thank you everyone.

I’m having the same issue with 3.6.0 however no amount of rebooting or erasing and reconfiguring wifi helps get it back online. Can you send me the firmware for a manual update?

Hi today my Unifi wifi access point restarted for a firmware update and so was offline for about 4 minutes. My AirGradient One I-9PSL-DE did not auto-reconnect. Stayed offline with red LED lit. I had to power cycle the unit.
It has firmware 3.6.0, serial# is 34b7dabd4c50 - can I please try the 3.6.2 or whatever firmware may fix this issue please?

Hi @Rev, thank you. We have started rolling out the 3.6.2. Some places might receive the update earlier or later. Please hang it there!
Hi @luckman212, I have set your place to get the 3.6.2. You can expect your monitor to be updated in a few hours. Alternatively, you can try power cycling (unplugging and plugging in) your monitor to force it detect the new firmware quickly.
Note: You might see the firmware dropdown selector blank, and the ‘Always update to the latest stable version’ unchecked. But please don’t worry, you don’t have to do anything, as the 3.6.2 is currently only visible to us at AirGradient. Users will see it as soon as we have it globally released.
Thank you all!
@Tai_AirGradient Thank you. I see my monitor already upgraded to 3.6.2. I will re-test it now.
update: good news, it seems to fix the issue where the unit would not re-connect after briefly losing the WiFi connection (e.g. for AP reboots).

@luckman212 That’s quick! Thank you a lot.
Please feel free to let me know if you experience any issues on the new firmware.
Today I woke up and both my devices
-
I-9PSL (SW 3.6.2)
-
O-1PST (SW 3.6.2)
are unable to connect to my WIFI
I restarted the I-9PSL, it couldn’t connect, but it provided a Wifi Network (airgradient-34b7da9fxxxx). So I connected to it, selected my Home Wifi SSID and PW, but it can’t connect. So it starts showing its Wifi Network (airgradient-34b7da9fxxxx) again.
Can someone please help me? Is this an issue with the subscrpition plan change that starts today?
Hi @funbrake, welcome to our community.
Please rest assured that the issue is not related to the subscription plan, as these air monitors are open-source hardware and software.
For your case, I think it’s possible that a disconnection occurred at some points.
You might want to try reconnecting the monitors to your Wi-Fi again (within 180 seconds after the monitor (outdoor) starts blinking, or displays “xxs to connect to Wi-Fi hotspot…” (indoor)).
If the connection is not made successfully within this 180-second time frame, the monitors will reboot themselves.
My unit (I-9PSL) just updated to 3.6.2 today and is often dropping out and reconnecting to WIFI, Which wasn’t the case before. Is there web flasher to downgrade? Downgrading through the dashboard is failing and the main tool AirGradient ONE (I-9PSL), Open Air (O-1PST) and Open Air Max (O-M-1PPST...) Firmware Versions is locked to 3.6.2. A Factory reset did not help.
Update, had to override DNS in my router settings, which let the AG One connect to the server and roll back its firmware. My existing DNS server works fine with 3.4.1. What is interesting is my resolver (AdGuard Home) was resolving fine and wasn’t blocking anything. There really needs to be an easy way to rollback an AG that is not connected to the internet.
The real issue is the firmware shouldn’t drop the WIFI connection if DNS isn’t working. (With or without post to airgradient enabled)
