Hello,
If you have a sensor that returns instantaneous power measurements (W or kW), to add a sensor that returns energy consumption or production (kWh), you need to use Riemann sums.
Do you think this could be added to Gladys or to the Zigbee module in question?
Why not!
I think the idea is pretty good! But I can’t vote — I’ve reached the limit.
Wait, actually it’s a device without an index?!
That’s what I understood: you have the power but not the consumption.
Yes, you have the power. And power is in watt-hours, so if your device consumes 1200 W and runs for 30 minutes you have consumed 600 Wh.
