bmr-hc64-client 0.1.1

Python library for communication with BMR HC64 Heating Controller units

bmr-hc64-client

Python library for communication with BMR HC64 Heating Controller units.

This is a fork of slesinger/pybmr

Features

• List, read and save heating circuits
• HDO reading
• List, read and set shutter blinds (experimental)

Product website:

• https://bmr.cz/produkty/regulace-topeni/rnet
• https://bmr.cz/produkty/regulace-topeni/rt64

Install:

python3 -m pip install bmr-hc64-client

Usage examples

Create connection

from bmr_hc64_client import Bmr

bmr = Bmr("http://192.168.1.5/", "username, "password")

Circuits

Get number of circuits:

numCircuits = bmr.getNumCircuits()

Load circuit status:

circuit = bmr.getCircuit(0)
print(f"Circuit {circuit['name']}: temperature is {circuit['temperature']} °C, target temperature is {circuit['target_temperature']} °C")

Load circuit schedules (what schedule is assigned to what day). It is possible to assign a different schedule for up to 21 days.

circuit_schedules = bmr.getCircuitSchedules(0)
print(f"Circuit 0 schedule for the first day is {circuit_schedules['day_schedules'][0]}")

Save circuit schedules:

bmr.setCircuitSchedules(0, [0, 8])

Schedules

Load schedules:

schedules = bmr.getSchedules()
print(schedule[0])  # Print the name of first schedule

Get schedule details:

schedule = bmr.getSchedule(0)
print(f"Schedule {schedule['name']} has timetable {schedule['timetable']}")

Save schedule:

bmr.setSchedule(0, "New schedule name", [("00:00", 21), ("06:00", 23), ("21:00", 21)])

Delete schedule:

bmr.deleteSchedule(0)

Summer mode

Get summer mode:

if bmr.getSummerMode():
    print("Summer mode is ON")
else:
    print("Summer mode is OFF")

Set summer mode:

bmr.setSummerMode(True):

Load summer mode assignments (which circuits will be affected by turning the summer mode on):

assignments = bmr.getSummerModeAssignments()
for circuit_id, value in enumerate(assignments):
    if value:
        print(f"Circuit {circuit_id} is assigned to summer mode.")
    else:
        print(f"Circuit {circuit_id} is NOT assigned to summer mode.")

Add circuits to summer mode:

bmr.setSummerModeAssignments([0, 1, 2], True)

Remove circuits from summer mode:

bmr.setSummerModeAssignments([0, 1, 2], False)

Low mode

Get low mode:

low_mode = bmr.getLowMode()
if low_mode['enabled']:
  print(f"Low mode is turned ON since {low_mode['start_date']}, target temperature is {low_mode['temperature']}")
  if low_mode['end_date']:
    print(f"It will be turned off automatically on {low_mode['end_date']}")

Turn the low mode ON, set temperature to 18°C:

bmr.setLowMode(True, 18)

Turn the low mode ON and let it turn OFF automatically after 3 days:

bmr.setLowMode(True, 18, datetime.now(), datetime.now() + timedelta(days=3))

Turn the low mode OFF:

bmr.setLowMode(False)

Load low mode assignments (which circuits will be affected by turning the low mode on):

assignments = bmr.getLowModeAssignments()
for circuit_id, value in enumerate(assignments):
    if value:
        print(f"Circuit {circuit_id} is assigned to low mode.")
    else:
        print(f"Circuit {circuit_id} is NOT assigned to low mode.")

Add circuits to low mode:

bmr.setLowModeAssignments([0, 1, 2, 6, 7, 8], True)

Remove circuits from low mode:

bmr.setLowModeAssignments([0, 1, 2, 6, 7, 8], False)

HDO

Load HDO status:

hdo = bmr.getHDO()
if hdo:
  print("HDO is currently ON")
else:
  print("HDO is currently OFF")

Backup of BMR Controler Unit Configuration

There is a CLI tool that can be used to backup configuration of actual BMR Controler Unit. It can be used in automations or just as a remote management tool. For more information refer to https://github.com/dankeder/bmrcli
