I am looking at comparing the readings from my SMETS2 smart meter (a Kaifa MA120) with the readings I am getting from a Victron VM-3P75CT, to see how they compare.
I can access the 10 second readings from my smart meter via my Octopus Home Mini - and making GraphQL calls to Octopus - which can return:
- readAt (ISO 8601 timestamp)
- consumption (Wh - meter reading)
- demand (Watts)
- export (Watts)
Does anyone know what the demand value is based on - is it an instantaneous power usage at that point in time, or an average over the previous 10 seconds?
I presume it is the same as the number displayed on In Home Displays.
Thanks!
