InfluxDB Error: unsupported mean iterator type: *query.stringInterruptIterator + Refresh issue

[Bboy486]

I followed the directions here - http://codersaur.com/2016/04/smartthings-data-visualisation-using-influxdb-and-grafana/

All good except for two issues

1. When I add a device I have to switch between attributes (temperature and contact for example) for grafana to pull in any data.

2. I am getting an error on a lot of devices - InfluxDB Error: unsupported mean iterator type: *query.stringInterruptIterator
