Hello, I am having an issue with multiple sensors on this hat. Just trying to troubleshoot, my question is that my I2c sensors run for a while then stop. I noticed the blue led on the grove board turns white when this happens. Can I ask what a white led means?
The white LED indicates that your SCL line is being held low. One of your sensors is failing (holding the line down). Remove your i2C sensors one at a time and find out which one is causing the problem.

Thank you. I only have a scd-30 and a gy-30 i2c connected. In the last 24hrs I've reduced my cron jobs to not overlap i2c sensor read. No lock up since. The scd-30 sensor operates differently than I am used to with its warm up required.
Do you know of a way to reset the i2c for remote devices when/if this happens since the only way it seems to reset is to remove power and plug back in. Reboot PI via restart will not work.

I will research that and learn. Appreciate the quick and great responses!
That part you linked looks perfect for my project. I bought 5 to test with just now. Just the piece of mind of having the ability is worth adding to our design. Thanks again and I will talk to you later.
5 stars on this hat. This has cleaned our project immensely!
