Custom library for electricity meters Neva MT 3xx
Project description
Library for electricity meters Neva MT 3xx
Working via serial port or RFC2217 server. IEC 61107 protocol is used (currently IEC 62056-21) and OBIS codes.
Installation
python -m pip install pyneva
Usage examples
From CLI
$ python -m pyneva -i rfc2217://192.168.88.109:1884 --val total_energy active_power --obis 60.01.00*FF
Connected to: [NEVAMT324.1106 : 11111111]
Values:
total_energy TotalEnergy(total=16484.51, T1=12896.28, T2=3588.23, T3=0.0, T4=0.0)
active_power ActivePower(sum=1499.8, phaseA=5.0, phaseB=1372.4, phaseC=122.3)
OBIS:
60.01.00*FF 60089784
From code
from pyneva import NevaMT3
# /dev/ttyX for linux local port
# comX or COMX for Windows local port
with NevaMT3("rfc2217://192.168.88.109:1884") as meter:
print(meter.model)
# NEVAMT324.1106
print(meter.serial_number)
# 11111111
print(meter.total_energy)
# TotalEnergy(total=16348.84, T1=12790.08, T2=3558.76, T3=0.0, T4=0.0)
print(meter.voltage)
# Voltage(phaseA=233.81, phaseB=233.02, phaseC=232.15)
print(meter.active_power)
# ActivePower(sum=1968.8, phaseA=5.0, phaseB=1833.4, phaseC=130.3)
print(meter.seasonal_schedules)
# (SeasonSchedule(month=1, day=1, weekday_skd_num=1, sat_skd_num=1, sun_skd_num=1),)
# Returns tuple with seasonal schedules.
# Each schedule specifies from which date the tariff starts,
# and the numbers of tariff schedules on weekdays, Saturdays, Sundays separately.
print(meter.special_days_schedules)
# ()
# Returns empty tuple if you have no special days tariff schedules (max 32 days).
print(meter.tariff_schedules)
# (
# TariffSchedule(parts=(
# TariffSchedulePart(hour=7, minute=0, T_num=1),
# TariffSchedulePart(hour=23, minute=0, T_num=2)
# )),
# )
# Returns tuple with tariff schedules.
# Each tariff schedule contains parts of the schedule.
# Each schedule part describes from what time of day the tariff starts
# and tariff number (T1, T2, T3, T4).
