Package: pyglowmarkt
pyglowmarktIntroductionPython API to the Bright/Glowmarkt/Hildebrand API for energy consumption.
There is a python API and a command-line script.For instructions on use with Home Assistant, seehttps://github.com/danmed/Glow2MQTTInstallpip3 install pyglowmarktAPI example usageConnectYou need an account fromhttps://glowmarkt.com/from glowmarkt import *

cli = BrightClient("myusername@example.org", "MyP4ssword!")Discover virtual entities and resourcesA virtual entity is e.g. your Glowmarkt device or SMETS2 smart meter.
A virtual entity has multiple resource e.g.Electricity consumptionElectricity costGas consumptionGas costents = cli.get_virtual_entities()

for ent in ents:
    print("Entity:", ent.name)
    for res in ent.get_resources():
        print("  %s:" % res.name)Meter readings over a period of timeAssuming we've got a resource from the discovery above...get_readingsreturns a list. Each element of the list is a[timestamp, value]pair which will be aKWHorPenceobject.
Usevalue.valueto fetch the floating point value, orstr(value)to
represent as a string with the kWh/pence unit.# Get time now, and 4 hours ago, this is the reading window
now = datetime.datetime.now()
t_from = now - datetime.timedelta(hours=4)
t_to = now

# Results will be summarised at one hour readings
period = "PT1H"

# Round times to start of period boundary
t_from = resource.round(t_from, period)
t_to = resource.round(t_to, period)

rdgs = resource.get_readings(t_from, t_to, period)
for r in rdgs:
    print("    %s: %s" % (
        r[0].astimezone().replace(tzinfo=None),
        r[1]
    ))Timezones are managed according to t_from and t_to.  If you want to use GMT
timezone, make sure t_from and t_to are set to use that timezone.Tarifft = res.get_tariff()
print("    Tariff: rate=%.1f standing=%.1f" % (
    t.current_rates.rate,
    t.current_rates.standing_charge,
))Not implemented / testedThe API provides the means to get the current value of a resource (the last
data point acquired) and the meter reading (the cumulative value, the number
you would see if you go and look at the meter.I can't get these to work, maybe not implemented, or maybe only work with
Glowmarkt hardware (I'm testing with a SMETS2 meter).Command lineglowmarkt-dumpAccesses the bright account and dumps out each resource's readings, and
tariff information, human readable.usage: glowmarkt-dump [-h] --username USERNAME --password PASSWORD
