Using BME680 sensor with BSEC

jsuanet · November 1, 2023, 7:29pm

Hi Doug,

I compiled your code with ESPHome version 2023.10.3 and after fixing two C++ errors in the interval: block it compiles without errors and no messages about bsec.h.

line 421 changed to:
lambda: 'return (id(auto_mode) == true);'

line 426 changed to:
lambda: 'return (id(mq8_percent_on) > id(bme688_percent_on));'

My question about which version of ESPHome your are using is still not answered but that’s an important one, also because the location for the build files is changed since 2023.9.0 (ESPHome 2023.9.0 - 27th September 2023 — ESPHome).

It looks like you are using a (very) old version of ESPHome, because if I look at the Dependency Graph in your log and my log, the version numbers are almost all higher in my log than in yours. And I’m also missing the first line containing the ESPHome version number. (See below).

Thank you so much Jos. I went to the link you provided to September 2023 - esphome and found that my version of esphome is totally outdated and uses .esphome rather than /src (that is why I could not find /src directory. BTW, I do not know how to find what version of esphome I have, but it is from when I grabbed the integration, perhaps years ago.
I really am embarrassed, but I do not know how to update my esphome. I have 28 devices in esphome and I would like to preserve them as best I can. Any advise?

I found the version under “add-ons” and it is 2022.3.1, with “auto update” set. Why is it not updating?

I did stop/start/restar on add-on/esphome and got the above saying 2022.3.1 is the latest??

Latest add on version 2023.10.5.

jsuanet · November 1, 2023, 10:17pm

See ESPHome 2022.2.0 - 16th February 2022 — ESPHome you have to remove the old one and install new one from different repo. Removing the old one doesn’t remove the yaml files, however a backup of your yaml files is always good.

dbasberg · November 2, 2023, 5:53pm

This was the answer! Your link took me to the fix. I now have esphome version 2023.10.5 and my yaml with bme680_bsec compiles successfully.
It is not possible to say how much I appreciate the work you put in solving this problem.
My programming skills were not adequate to solve this. Perhaps there are others this will help.
I am surprised that the add-on section setting of “auto-update” neither updated or warned of a problem.
How many of my add-ons have this problem?
THANK YOU SO MUCH JOS!

Glad to read your problem is solved!

I don’t think you will have an update problem with other add-ons. This was a special one. ESPHome was a community add-on which was adopted by the HA-team as an integral part of HA, so they moved it to the official HA repro. It was also announced in one of the HA release-notes. So it is always good to check the monthly HA release notes for breaking changes.

My Olimex ESPs require the ESP-IDF framework, which (according to the Bosch forum) isn’t supported:

The current BME688 BSEC software does not support ESP-IDF

It seems like there is a new BSEC2 implementation but it shows that ESP32 IDF wasn’t tested

# What does this implement/fix? This should be in draft state, because we sho…uld probably wait for a new release of the BSEC2 library. This is a new integration based on the bme680_bsec component, updated to the BSEC2 library by Bosch. This supports BME688 sensors. Unfortunately binary configurations settings are needed for 3,3V operation, that are not included in the public repo. I requested them here: https://github.com/boschsensortec/Bosch-BSEC2-Library/issues/20 You can get the configuration files by requesting the SDK from the Bosch website. bme680_bsec already supports multiple sensors. I chose not to include these commits in my branch, because a native implementation was added in bsec 2.4 (https://github.com/boschsensortec/Bosch-BSEC2-Library/issues/3). BSEC 2.4 is not available on GitHub yet. BSEC 2.4 will be a unified version that also supports BME680 ## Types of changes - [ ] Bugfix (non-breaking change which fixes an issue) - [X] New feature (non-breaking change which adds functionality) - [ ] Breaking change (fix or feature that would cause existing functionality to not work as expected) - [ ] Other **Related issue or feature (if applicable):** fixes https://github.com/esphome/feature-requests/issues/1332 **Pull request in [esphome-docs](https://github.com/esphome/esphome-docs) with documentation (if applicable):** esphome/esphome-docs#4018 ## Test Environment - [X] ESP32 - [ ] ESP32 IDF - [ ] ESP8266 (NOT working, `section '.text1' will not fit in region 'iram1_0_seg'`) - [X] RP2040 (Couldn't get ESPhome working with dev branch, BSEC2 broken until https://github.com/boschsensortec/Bosch-BSEC2-Library/pull/22 is merged) ## Example entry for `config.yaml`:  ```yaml bme68x_bsec2_i2c: address: 0x76 model: bme680 operating_age: 28d sample_rate: LP supply_voltage: 3.3V sensor: - platform: bme68x_bsec2_i2c temperature: name: "BME688 Temperature" filters: - median pressure: name: "BME688 Pressure" filters: - median humidity: name: "BME688 Humidity" filters: - median iaq: name: "BME688 IAQ" filters: - median iaq_static: name: "BME688 Static IAQ" filters: - median co2_equivalent: name: "BME688 CO2 Equivalent" filters: - median breath_voc_equivalent: name: "BME688 Breath VOC Equivalent" filters: - median gas_resistance: # Gas resistance in Ω name: "BME688 Gas Resistance" filters: - median ``` ## Checklist: - [x] The code change is tested and works locally. - [x] Tests have been added to verify that the new code works (under `tests/` folder).
