# SolarView is a powerful ;) datalogger for photovoltaic systems that runs on
|
||||
# an AVM Fritz!Box (and also on x86 systems). For details see the SV homepage:

# http://www.amhamberg.de/solarview_fritzbox.aspx

# http://www.solarview.info
|

#
|

# SV supports many different inverters. To read the SV power values using
|
||||
# this module, a TCP-Server must be enabled for SV by adding the parameter
|
||||
# "-TCP <port>" to the startscript (see the SV manual).
|
||||
#
|
||||
# usage:
|
||||
# define <name> SolarView <host> <port> [<interval> [<timeout>]]
|
||||
# define <name> SolarView <host> <port> [wr<i> wr...] [<interval> [<timeout>]]
|
||||
#
|
||||
# example:
|
||||
# define sv SolarView fritz.box 15000 wr1 wr2 60
|
||||
#
|
||||
# If <interval> is positive, new values are read every <interval> seconds.
|
||||
# If <interval> is 0, new values are read whenever a get request is called
|
||||
# on <name>. The default for <interval> is 300 (i.e. 5 minutes).
|
||||
#
|
||||
# get <name> <key>
|
||||
# The parameters wr<i> specify the number(s) of the inverter(s) to be read.
|
||||
# When omitted, the sum of all inverters is read. If more than one inverter
|
||||
# is specified, the names of the readings are prefixed with the inverter
|
||||
# number, e.g. 'wr2_currentPower'.
|
||||
#
|
||||
# get <name> [wr<i>_]<key>
|
||||
#
|
||||
# where <key> is one of currentPower, totalEnergy, totalEnergyDay,
|
||||
# totalEnergyMonth, totalEnergyYear, UDC, IDC, UDCB, IDCB, UDCC, IDCC,
