ESP8266 - bme680_bsec no sensor values after 24-48hours

ESPHome
1

Hello, first of all, thank you so much for that ESPHome thank you for the project and all those who are involved in it. I have set up a few sensors and i think the project is brilliant!

I currently have four sensors based on an ESP8266 / wemos (different types and hardware revisions). Three of them are running without any problems so far (with 1-wire/ds18B20, analog-in and BME280). A newly installed one with BME680 (bme680_bsec) initially runs without problems and as desired, but then after 24-48 hours no longer delivers any values from the BME680. Analogue-In and Binary-In continue to work without problems, and the sensor is still accessible and responsive. Values from the BME680 only come back after a hard reset (disconnection from the power supply for a few seconds). In the meantime, I have tested 3 different power sources with which all other sensors run without problems.

As error I receive

[E][bme680_bsec.sensor:134]: Communication failed (BSEC Status: 0, BME680 Status: -2)

from the log. BSEC Version is 1.4.8.0, sensor running under sample_rate ulp.

On this basis, does anyone already have an idea for the cause or what information or tests should i provide, if any?

Thanks!

I found this:

Similar “-2” error and duration of time where it runs until failure.
It appears to be a signalling issue which can be resolved by grounding the CS pin on the module.

7

i had the same issue, and found that the BSEC Library is for the Sensor i2c Adress 0x77.
(not perfect that the docs for ESPHome have Default Adress 0x76)

I solved it to changed the i2c Adress of the Sensor to 0x77 (GND PIN one time at SPO PIN, then Restart, after that you see the 0x77 in the ESPHome Logs), and change the ESPHome Adress to 0x77, then it worked for me.

So, do you leave CS connected to Ground? Like… actually wire ground to CS?

9

Do you need to do this every time the ESP and BME sensor are powered off and on! Short the pin to ground?

10

Hi! When I said ground, it was just another (somewhat incorrect) word for negative. You just connect negative to CS (chip-select) and try that. Hope it helps.

Yup…ground made sense too lol. Thanks man. I’ll test that out. Thanks for the follow up!
