Looks like I’ve got the same issue. There is 20 min worth of missing data on a regular basis, and i only ever 50% data quality in the feed summary. All other feeds maintain ~100%.
This is the data from my newly added ‘solar diverted’ feed. This is CT on the live wire of a cable running from an mk2router to the immersion tank. Below is a night time data set (so no current to measure).
Below is day time data set:
The CT is connected to a TX, running a modified sketch from Robert Wall,
