This piston will create gauge tiles and piston state for a HEM.
The piston shows:
- Power
- Energy
- Current (calculated)
- Cost (calculated)
You can set your cost per kWh in the variable. Cost is a simple calculation assuming a flat rate per kWh. I believe there’s another example in here that calculates based on time of day.
Make sure to put the piston in a category that shows tiles to get the gauges:
I prefer the medium-sized gauges but note with it set to medium you won’t get the piston state display.
