ESPHome One spamming logs with mismatch warnings

#1

Hoping someone familiar with MallocArray’s Airgradient ESPHome repo can assist.

I have two Airgradient One’s that I’ve updated with ESPHome from the above mentioned repo.
Every 30seconds the log displays the following:
[10:58:20.306][W][pmsx003:158]: PMSX003 checksum mismatch! 0x262 != 0x1C
[10:58:20.307][W][pmsx003:125]: Start character 1 mismatch: 0x00 != 0x42
[10:58:20.307][W][pmsx003:125]: Start character 1 mismatch: 0x00 != 0x42
[10:58:20.307][W][pmsx003:125]: Start character 1 mismatch: 0x00 != 0x42

pm2.5 values are inline with what they were before the firmware change. I’ve also done a manual power cycle to see if it resolves the issue.

Changes I’ve made to the yaml:

added to bottom of substitutions:
pm_2_5_scaling_factor: ‘0.03863’
pm_2_5_intercept: ‘0’

below the wifi section and above the dashboard import I added:
bluetooth_proxy:
active: true

esp32_ble_tracker:
scan_parameters:
window: 290ms
interval: 320ms
active: true

I also have the same issue

I originally reported it here:

But they closed that particular repo and despite asking, doesn’t look like it was moved to the current issue tracker, so I’ll see if I can open it myself there as well.

Other than the logs being chatty, everything is working, correct?
