Hi, I was building a Dashboard for my UPS using telegraf and the apcups plugin and noticed that the status of the UPS is mapped as a TAG, is there a way to build a Singlestat for it? I was trying something like
> SHOW TAG VALUES FROM apcupsd with Key=status
name: apcupsd
key value
--- -----
status ONLINE
But this seems to only work for a table… Any help is appreciated.
Thanks
I’ve also tried to pull the data from my Home Assistant Influxdb data and still got the same NULL result 
Trying on command line:
> SELECT "state" FROM "sensor.ups_status" WHERE ("entity_id" = 'ups_status')
name: sensor.ups_status
time state
---- -----
1586606496812936192 ONLINE
But on Grafana it won’t show and I think its because it only updates on changes, so the timeframe will not capture it…
