About the same. I’m not getting as frequent of reboots, but they do happen sometimes, but I also see the unmodified ESPHome install with similar stability, so I don’t know what to think

Same here. Occasional reboots every other day. It would be best to find out where it is coming from for every crash but that requires logging everything from serial and possibly removing and adding every single sensor to reduce the possibilities. At this moment it isnt really convenient for me to do that and I don’t have a second board to test it. I don’t really want to stop logging data for too long.
Another way to look into these issues is to look here GitHub - nkitanov/iaq_board: IAQ Board is a DIY (Do-It-Yourself) device for measuring internal air quality
It looks like most of the hardware is the same and they encountered the sgp31 issues also.
Or just put all the sensors on a breadboard and see if the same issues arise after a while.
If someone has a good test strategy we can try to collectively find the main issue(s)
It’s either an individual, hardware specific issue (not likely, since there are multiple of you), or there is an issue with ESPHome. I say that because I’ve been running mostly-stock AirGradient code with OLED, SHT, TVOC, S8, PM5003 on a modified v3.3 PCB with OLED on 5V and SHT on 3.3V, I2C at 100kHz, Arduino Core 3.1.0, Software Serial v6.12.7 and it has been running non-stop for 17 days, 21 hours, and 9 minutes with zero reboots, zero sensor dropouts/timeout. Rock solid.
I’d concur that there is a problem with ESPHome. Having reduced the pair of devices I have to just literally the ESPHome WiFi stack and an uptime sensor, they still reboot every few hours.
It’s worth noting that ESPHome has several built-in reboots e.g. WiFi drops for a period, though detecting these is tricky when the presence of debug logging seems to sometimes be enough to cause more instability!
What I notice about @argafal’s approach is that the Home Assistant native API is not in use. I might have to try the MQTT approach. Despite the native one being ‘recommended’, I generally have more faith in MQTT.
Thanks all by the way for chipping in thoughts, this is both frustrating and interesting!
Having trialed some changes for a while, I am fairly confident in saying that this set of ESP lines are causing the problem for me. No sensors needed, just enabling UART seems to start reboot cycles. Remove this and the device is rock solid (albeit doing very little!)
esp8266:
board: d1_mini
framework:
version: recommended
platform_version: 3.2.0
esphome:
name: "${devicename}"
libraries:
- uart=https://github.com/plerup/espsoftwareserial.git#6.17.1
# Remove this, reboots solved
uart:
- rx_pin: D5
tx_pin: D6
baud_rate: 9600
id: uart1
- rx_pin: D4
tx_pin: D3
baud_rate: 9600
id: uart2
So this does seem to point back to some instability around the UART code again, but I was under the impression 6.17.1 did not have the major errors the new versions did. Very odd; I’ll see if I can carve out some time to see what the actual reboot failures are.
The graph downloaded confirms that, unless the build is really broken in dependency management somehow, that it has the right libraries

Just following up, I got the following software WDT errors in two stack dumps

(Stack 2 in next post due to post length)
which both look reliably inside ESP8266SoftwareSerial::read_bit
I’m not sure I’m much closer to understanding the problem, though I shall try again with SoftwareSerial 8.0.1 and see if anything changes. I did read on espsoftwareserial github that there can be issues with WiFi interrupts being higher priority than UART interrupts and thus WiFi can be a potential cause of timeouts, so I think that’s probably my next mole to try whacking…
It’s slightly frustrating to keep running into advice that could be summarised as ‘Don’t use ESP8266’ when the existing Pro hardware is already purchased & using it

I’ve been away for a bit but I’ve seen my device mostly restart on hardware wdt and a occasional wdt 4 so software. No stack dumps saved sadly. My uptime is now around 5/6 days. And I also run espsoftwareserial 8.0.1 and all other the recommended versions.
I have about 20 esp devices with esphome and all run the native api. Only the airgradient has reset issues so I don’t want to blame the api at this point. Many have uptimes of months.
I’ve seen that esphome 2023.4.2 released today has a fix for i2c reset issue which can cause a hardware wdt. I updated immediatly and I will test again for next days/weeks. If it only resets on software error it makes it a lot easier to debug.

Some progress. I was able to narrow down the UART problem more. The specific problem area seems to be 9600 baud. If I init the board with this, I’ll get regular reboots (with zero sensors listed in ESPHome). With 115200 (which of course renders the associated sensors useless), the board appears to be stable.

I just found a Github issue that sounds almost identical to this problem. Frustratingly it was closed as theoretically fixed in ESPSoftwareSerial 5.3.0. It’s still interesting to see that this sort of thing has cropped before.

I was curious if anyone on this thread has had any luck proving that ESPHome actually pays attention to version information. I notice some really odd behaviour, when I select framework version & platform_version.
Changing version to e.g. 3.1.1 yields no change other than a warning about not using the recommended version.
Changing platform_version yields no messaging whatsoever.
Changing both to e.g. 3.1.1 & 3.2.0 respectively yields weird messages like Installing platformio/framework-arduinoespressif8266 @ ~3.30101.0, which bears no resemblance to 3.2.0, but does mention 3.1.1 in its documentation (3.1.1 of what, nobody bothered to document).
None of this behaviour seems to match what is written in ESPHome’s documentation.
Other than whichever bunch of devs responsible for this need training in versioning semantics and documentation, does anyone know whether we can prove we’re actually running a given version of these packages?
ESPHome’s build dependency graph looks to be semi-useless, because it doesn’t even mention any of these packages.
I should add, to the above, the reason I’m trying to narrow this down is that with version: latest, platform_version: 4.2.0 and ESPSoftwareSerial:8.0.3 I’m suddenly getting hardware watchdog timeouts, whereas a board with just version: recommended and ESPSoftwareSerial:8.0.1 is still stable (if no UART sensors), but it’s currently impossible to prove anything as to what I’m changing!
In my experience it uses the right version and installs a new version if it isnt cached. I don’t think it is ever possible to ask code which version it is because is dependent on the developer to put that into a debug message or so. The reason I know changing arduino versions works is because dependencies are changed and my device did respond different and some bugs have gone away.
To give a little update on my crashes. It only happens every few weeks now. The i2c fix has helped in my instance. Most of the time its hardware watchdog. I run the recommended arduino framework and espsoftwareserial 8.0.1.
Thanks @Hendrik - out of curiousity, is your full config posted anywhere? I’d be interested to compare, as I’m still at the point where if I do have reboots, it’s software watchdog every few hours.
This is my working version. I will update it soon because I will change the tvoc sensor.
