# OWCOUNT.pm
#
# FHEM module to commmunicate with 1-Wire Counter/RAM DS2423
#
# Attention: This module may communicate with the OWX module,
# but currently not with the 1-Wire File System OWFS
#
# Prefixes for subroutines of this module:
# OW = General 1-Wire routines Peter Henning)
# OWX = 1-Wire bus master interface (Peter Henning)
# OWFS = 1-Wire file system (??)
#
# Prof. Dr. Peter A. Henning, 2012
#
# Version 2.25 - October, 2012
#
# Setup bus device in fhem.cfg as
#
# define <name> OWCOUNT [<model>] <ROM_ID> [interval]
#
# where <name> may be replaced by any name string
#
# <model> is a 1-Wire device type. If omitted, we assume this to be an
# DS2423 Counter/RAM
# <ROM_ID> is a 12 character (6 byte) 1-Wire ROM ID
# without Family ID, e.g. A2D90D000800
# [interval] is an optional query interval in seconds
#
# get <name> id => FAM_ID.ROM_ID.CRC
# get <name> present => 1 if device present, 0 if not
# get <name> interval => query interval
# get <name> memory <page> => 32 byte string from page 0..13
# get <name> midnight <channel> => todays starting value for counter
# get <name> counter <channel> => value for counter
# get <name> counters => values for both counters
#
# set <name> interval => set query interval for measurement
# set <name> memory <page> => 32 byte string into page 0..13
# set <name> midnight <channel> => todays starting value for counter
# set <name> init yes => re-initialize device
#
# Additional attributes are defined in fhem.cfg, in some cases per channel, where <channel>=A,B
# Note: attributes are read only during initialization procedure - later changes are not used.
#
# attr <name> event on-change/on-update = when to write an event (default= on-update)
#
# attr <name> UnitInReading = whether the physical unit is written into the reading = 1 (default) or 0
# attr <name> <channel>Name <string>|<string> = name for the channel | a type description for the measured value
# attr <name> <channel>Unit <string>|<string> = unit of measurement for this channel | its abbreviation
# attr <name> <channel>Offset <float> = offset added to the reading in this channel
# attr <name> <channel>Factor <float> = factor multiplied to (reading+offset) in this channel
# attr <name> <channel>Mode <string> = counting mode = normal(default) or daily
# attr <name> <channel>Period <string> = period for rate calculation = hour (default), minute or second
#
# In normal counting mode each returned counting value will be factor*(reading+offset)
# In daily counting mode each returned counting value will be factor*(reading+offset)-midnight
# where midnight is stored as string in the 32 byte memory associated with the counter
#
# Log Lines
# after each interval <date> <name> <channel>: <value> <unit> <value> <unit>/<period> <channel>: <value> <unit> <value> <unit>/<period>
# example: 2012-07-30_00:07:55 OWX_C Taste: 17.03 p 28.1 p/h B: 7.0 cts 0.0 cts/min
# after midnight <new date> <name> <old day> <old date> <channel>: <value> <unit> <channel>: <value> <unit>
# example: 2012-07-30_00:00:57 OWX_C D_29: 2012-7-29_23:59:59 Taste: 110.0 p, B: 7.0 cts
