No data recorded after 'Clear Feed' is used

borpin · 2018-11-14T18:14:37.466Z

I have a feed generated from an MQTT source

I used the ‘clear feed’ functionality to clear the data, but now no data is recorded.

The meta file simply has a x in it.

Log extract (grep on =30)

You can see the call to clear

The get_data() calls are probably me trying to view data. Each time the number of points returnd is zero though it seems to be trying to insert_data.

Just checked again and only 'null is being stored (it seems - CSV output - dates will not match)

"Unix timestamp", "xiaomi:xia-0c-Hum"
1541612700, null
1541613600, null
1541614500, null
1541615400, null
1541616300, null
1541617200, null
1541618100, null

The tool tip does not show a start time.

As opposed to one that is working…

The feed list shows it is being updated.
