BME280 errors when WiFi is unavailable #3530

Closed acronce closed 1 year ago

acronce commented 2 years ago

The problem

I'm preparing an ESP32 based sensor as a gift. To that end I've configured it with that person's WiFi credentials. But when I boot the device after changing the credentials the BME280 sensor doesn't initialize (i.e. has_state() reads as false).

If I go into the device via captive portal and configure it for my network, the BME280 sensor starts working. It's as if lack of available WiFi or the presence of the device's AP is interfering with the I2C bus.

The other sensors (pmsa003 and senseair) work fine when WiFi is unavailable.

I've tried a few things, like increasing the frequency and changing the setup_priority of the I2C bus, but have not been able to work around this issue.

I realize that it's unusual to have an ESP device that's not connected to WiFi, but in this case the unit has its own display and can function without a network. It would be nice if the temperature sensor works when WiFi is unavailable.

Which version of ESPHome has the issue?

Version: 2022.5.1

What type of installation are you using?

pip

Which version of Home Assistant has the issue?

N/A

What platform are you using?

ESP32

Board

LILYGO® TTGO T-Display 1.14 Inch LCD ESP32 (16MB CH9102F Chip)

Component causing the issue

i2c or WiFi

    humidity:

Anything in the logs that might be useful for us?

I don't know how to get the logs when the device is in captive portal mode, and the problem goes away when the device connects to WiFi. I cannot connect via USB due to the port being blocked in my installation.

Have same issue. I checked uart logs:

[02:11:40][V][bme280.sensor:203]: Sending conversion request...
[02:11:40][C][bme280.sensor:086]: Setting up BME280...

That message repeats twice per second until wifi is connected

UPD. Removed from config everything except i2c, bme280 and logged in VERY_VERBOSE mode. Logs:

Again, thanks for your help.
