BME680 Not Working After Migration from V1

[mbauer599]

I'm having the following issue, multiple BME680 sensors are failing to work with v2 out of the box -- sensors that were (and are) working with v1. I'm using devices that are being migrated from a v1 project, so this could be the issue. Any help on how to do this properly is appreciated.

Looks like sensor script is failing and hanging:

I will stress that it's working on V1 so I don't think hardware is the issue. As well, I have updated to SUPERVISOR VERSION 12.8.8 from 10.x and have the issue on both.

What type of device are you using?

[mbauer599]

Multiple BME680s. If you are looking for manufacturers:

• Adafruit
• KOOBOOK
• ACEIRMC

I also am using a Sense HAT that also does not appear to work, however I did not (and have not) tested this on V1 so I'm excluding this for now. I also have done exactly no troubleshooting on the Sense Hat so asking for help wouldn't exactly be fruitful.

I will point out that this is probably something on my end (how I set it up or whatnot) but for V2 I have it deployed to it's own (clean new) project and did attempt to perform both a migration and a fresh build with the same effect. I'm running a PI Zero, a PI 2, and two PI 3's.

Sense V2 won't work on the Pi Zero because Influx does not have an ARMv6 build, but there should not be an issue with the Pi2 or 3. What version of balenaOS are you running?

[mbauer599]

In the long run that's not an issue for me, since I'm using a centralized Influx/Grafana for all my sensor data (one view for many rooms in my house), although I haven't even thought about building this for V2 of this project yet. Need to get the sensors working first.

Copied from my PI 2: SUPERVISOR VERSION -- 12.8.8 HOST OS VERSION -- balenaOS 2.48.0+rev1

I'm also running: balenaOS 2.54.2+rev1

Would updating this version be of use for testing or functionality?

FWIW, I was hitting this error and updating the host OS (2.98.33 after the update) worked for me. I believe this is due to the use of the kernel modules for IO in v2

[mbauer599]

As of the time of this error occuring, updating the os did nothing. I did try running on multiple pi's as well (multiple versions of pi too, including a 2/3/4) to no avail. I tried upgrading and downgrading os to no avail. I actually just gave up and rolled my own since my target was pi zeros anyway, pushing to cloud influxdb and grafana cloud so I don't need any more power on the pi.
