I noticed my O-1PST monitor doesn’t show temperature history correctly in Home Assistant. I removed and re-added it to see if it made a difference without any luck. The O-1PST shows graphs normally on the airgradient dashboard.
My other 3 indoor monitors work ok.
Looks like you had one significant dip to ~-1000 and it throwing off your entire graph. If you change the graph time to only the last 4 hours, I bet it shows correctly and once that dip ages out, your graph will look normal.
I think I saw someone else mention erratic temp readings and it was being fixed in an upcoming firmware.
Good catch… so something is causing the ocassional “bump” down to -1000.00 C. I look forward for the next firmware to resolve that.
We will fix this on the firmware side.

Is this coming for DIY Pro PCB 3.7 as well, or is it just for the ONE? Our ESPHome firmware has always been randomly flaky/randomly freezes after a couple days for some reason, so really looking forward to the possibility of a native integration.
Hello!!
I began to investigate and learn about the integrations of IoT devices using HA and being able to have AirGradient monitors locally online, here is a summary of what I observed and learned:
I have two Open Air monitors, (1 model O-1PP Firmware Version: 0.6.4 and 1 model O-1PS Firmware Version: 3.1.4)
When I configure my HA for the first time and activate the corresponding services, the model with firmware 3.1.4 is automatically detected. Not so the other one. So I tried several times to update following your instructions through the ESPHome service, but I ended up giving up and installing the latest version of the firmware directly from the firmware session but when detecting the monitor, it told me that version 3.1.1 was required; so I proceeded to install the recommended firmware and now it was recognized in HA.
But, this morning when I check the versions of the monitors, I realize that both now have the same version 3.1.4 and are both online in my HA. I understand that one has been updated remotely (OTA), is that correct?
These are just observations and comments about my experience setting up an integration in HA.
I’ve found my DIY Pro also occasionally crashes with ESPhome firmware. Not often enough to investigate though… maybe once every 2-4 weeks.
My DIY Open Air has been stable.
Hi Luciano, nice to see you here in the forum!
Yes the observations you made are as they should be.
The push button of PCB3.7 is currently not supported but it will be compatible with Home Assistant and you should be able to make all configuration changes directly from Home Assistant.
More information on how to flash this version is here:
Thanks! Tried it on a few of our 3.7s, seems to work alright, though the server connection seems a bit flaky, the entities going “unavailable” pretty frequently. But it’s better than the crashes I was seeing with ESPHome, since I’d have to manually power cycle them. That got old fast.
Will this all be coming out for v3.3 as well?
I’ve been observing reboots with ESPHome and the ESP8266 devices ever since the beginning, but other than resetting the TVOC index, it hasn’t overall impacted the functionality.
The latest release is working much better for the newer devices with the ESP32-C3 chips due to a watchdog timeout extension option that isn’t available for the lower end chips
