BME680 Reporting the wrong big value for Gas Resistance (and therefore all the other divided parameters )

tactmaster commented 1 year ago

The problem

I have a BME680 on a sense board. https://www.kickstarter.com/projects/nexuselectronics/sense-an-open-source-environment-monitor.

The Gas resistance doesn't change it is always at 12887828.00000. It effects booth the bme680 and bme680_bsec competents

So I have tested the on a raspberry pi with the examples given adafruit lib (non BSEC lib). I have tried with the platform io using this example. It work fine. https://registry.platformio.org/libraries/boschsensortec/BSEC%20Software%20Library/examples/basic/basic.ino It uses BSEC code 1.8.1492.

From looking at the ada fruit code it would appears to be 2 variants of the the BME680

Which version of ESPHome has the issue?

2023.3.2

What type of installation are you using?

Home Assistant Add-on

Which version of Home Assistant has the issue?

2023.4.2

What platform are you using?

ESP32

Board

featheresp32, esp01_1m

Component causing the issue

bme680,bme680_sec

Example YAML snippet

esphome:
  name: sensor2
  friendly_name: sensor2

esp32:
  board: featheresp32
  framework:
    type: arduino

web_server:
  port: 80

i2c:

bme680_bsec:
    address: 0x77

sensor:
  - platform: bme680_bsec
    gas_resistance:
      name: "BME680 Gas Resistance"

Anything in the logs that might be useful for us?

No response

Additional information

I am trying to upgrade the from version BSEC version 1.6.1480 to 1.8.1492. However the structure has changed to the lib a little bit, I am not that experience with ESPHome code but i I would give it a go.

Hi, you have a BME688, that's why the resistance value is different. Search for BME688 in ESPHome's feature requests, I think there is a custom component.

Yes you are right. Thanks Here: https://github.com/esphome/feature-requests/issues/2134 https://github.com/esphome/feature-requests/issues/1332

The PR is here https://github.com/esphome/esphome/pull/4585 It seems to work (i compile it from the dev environment and rebased it )
