Power Monitoring "Dashboard": Can it be done?

Hubitat in use: C-8 non-pro

Ladies and Gentlemen:

Setting the Table: I have a bunch of Third Reality Zigbee plugs with power monitoring capabilities. I can see the measurements by going into Devices | [a power monitoring plug] | Commands and reading the Current States frame.

What I want to do: Is there a means of pulling this data out and displaying it some way? I am thinking of something in a dashboard, but have no idea how to do this. I daresay I've never even done anything with a dashboard at all except start one and foul it up so badly I delete it.

Your thoughts?

Note to the Hubitat people: I am thinking of moving up to a C-8 Pro. This will likely be around June or July. So, don't bring out the C-9 until August! :grin:

Sure. You just have to figure out what template gives you watts, amps, voltage. [Note: This is with classic dashboard.]

Not strictly a dashboard as such but a great app to easily give you some historical information and display your usage:

I use grafana with influxdb. Lets me embed graphs in other things in addition to my dashboard.

I use the power monitoring capabilities of outlets solely for triggering rules. While I could show them on a dashboard it might get bit messy/busy having the values from multiple outlets updating regularly.

For my dashboard I’m using a home energy monitor that is clamped onto the tails of the incoming supply. I use values from that to populate some variables that are displayed on my dashboard. I’m displaying:

  • energy in KW/h. That’s cumulative for the day and resets at midnight
  • Cost. Also resets at midnight. To get that I have a rule/node-red flow that multiplies energy by the unit rate and adds the standing charge
  • Power. Updated every 2 mins. How much I’m using at that instant.
  • Peak power. Rule compares each power reading to to Peak power. If power is higher than peak power it sets peak power to the new higher value. I set this to 0 at midnight (to ensure the first reading coming through is higher)
  • Min power. Similar to above but stores the lowest reading (and I set that to 1000 at midnight). I’m using that to see what the minimum usage can be. Currently on holiday but various devices that must be on are using a minimum of 220W.
