Monitoring results from a 5kW Ecodan heat pump

You can tell I was really happy with this code @abbbbbottttt:


def getEnergy(self):
    # TODO: Misses the last hour because of BST
    for i in [-2, -1, 0]:
        fromDay = datetime.date.today() + datetime.timedelta(days=i)

        fromDate = "{:%Y-%m-%dT%H:%M:%S}".format(fromDay)
        argh = {
            "DeviceId": 191113,
            "FromDate": fromDate,
            "ToDate": fromDate,
        }  # "UseCurrency":False
        energyJSON = self.getContent("EnergyCost/Report", argh)

@MyForest Thank you. Out of interest, how come the readings, if you’re just comparing current to previous?

Hey @abbbbbottttt

I was actually capturing these readings for some other purpose. It was only when the other ones vanished that I started using this one for working out the energy delta.

@MyForest Thank you. I’m really close to having everything up and running now but I seem to be getting all 0 values when I run the Energy Report for today:

Hi @abbbbbottttt

That is odd.

You have averages in your list that I don’t have. Mine is an FTC5, I’m assuming yours is an FTC6.

Do you see the data you’d expect in MELCloud itself?

Here’s what I just received from mine:

@MyForest - Yes, FTC6. Unfortunately, I don’t seem to see the energy report for today either which is a bit disappointing. So it looks like I’m left without the capability to get up-to-date energy use at the moment. Thanks for all your help!
