When you changed your settings, did you click “save”? You always need to save the settings for them to take effect. Can you post a screenshot of your settings?
Yes I always hit save. Always have a green connection light.
This is my setting and then the measurements that have been taken every hour. Almost perfect and well within the massive buffer that I set to try to get it to stop testing every hour.
Low-8. High-10. It should not retest because it’s been solid around 9dkh.
