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)

Hi @Austin_Richards, thank you for the update.
I agree that there should be an easy way to roll back the firmware for non-dashboard users. I will discuss this with our engineers and see what’s the best solution we can provide.
For the Wi-Fi issue you are experiencing, I’ll bring this up with @Samuel_AirGradient to take a deeper look at it.
3.6.2.is better at reconecting bu stil req maual reboot sometimes.

Hi @TeMpL, thanks for your feedback!
Would you mind giving us more information about the issue you have been encountering? Does it still sometimes disconnect and not reconnect automatically?
I have been seeing the WiFi disconnect issue for a while and just ran across this thread. Both of my devices (one indoor, one outdoor) are on 3.6.2 and I have had to power cycle both of them in the past 24 hours. It’s gotten to the point where I have a Zigbee power plug on the outdoor one so I can cycle it remotely via. Home Assistant.
To the earlier post, here is what I have:
- Model number of the monitor that has the issue? (I-9PSL-DE, O-1PST, etc.): I-9PSL & O-1PST
- Please describe the symptom of the issue you experienced. It seems to randomly disconnect. I haven’t tried to track the disconnects, but from a quick look at the data history in Home Assistant, it is fairly random (The outdoor one failed just just after midnight one day and two days later at at 3PM; indoor failed at different days and times)
- What does the OLED screen of the monitor show when it is disconnected? And what is the color of the LED on the left of the monitor (red, purple, etc.)? I haven’t paid attention to the screen, but the LED is white on the indoor model.
- Network setup: Describe your network setup. Please also specify the brand and model of each network equipment. On the WiFi side it is a Asus ZenWifi mesh – two devices, running in AP mode. Those connect to a Cisco switch, that connects through a pfSense firewall to get to one of my two WAN connections.
- AirGradient monitor configuration - accessible via web browser with a phone or computer connected to the same Wi-Fi as the monitor that has the issue using:

- Is your Wi-Fi network using a unified band (a combined Wi-Fi name without separating 5GHz and 2.4GHz)? Yes
- Is your Wi-Fi a mesh system, have multiple access points, or use Wi-Fi extender? Yes
- Do you have your Wi-Fi DHCP server configured to assign a static IP address for connected devices? Not for these two devices
- Does the monitor connect to the AirGradient dashboard? Yes
- Does the monitor connect to Home Assistant or other platforms? Yes
- Is this Wi-Fi issue gone after you downgrade your AirGradient monitor from firmware 3.6.0 to 3.4.1? I haven’t tried this yet

Hi @sjthespian, thank you so much for reporting this!
@Samuel_AirGradient, could you please take a look if we can do something with this or need any further information for the investigation?
My O-1PS dropped off my network on February 12, but I’m unfortunately just getting to trying to fix it now. It last reported with 3.6.0. A reboot did not fix it, so I manualy erased it and flashed 3.6.2. It sees my WiFi networks but fails to actually to connect to any of the ones I’ve tried. My I-9PSL runs 3.6.2 just fine on the same SSID. I even tried a 2.4GHz-only SSID.
I wanted to try downgrading the firmware to verify that the hardware still functions, but the firmware page appears to only list the latest versions. Would I need to build the firmware myself and manually flash it with Arduino software?
Hi @Shinji! Have you tried to connect it to a mobile hotspot temporarily and see if it connects? Meanwhile @Tai_AirGradient will be in touch on Monday and have a deeper look for you! Perhaps you can also take a debug log and send it to us: https://www.airgradient.com/support/
