Figure 3. A3 ALPHA meter with ITM3 RJ-11 cable
Metering Software and
System
To have the A3 ALPHA meter function properly as a data collector in the
EnergyAxis System, it is important that the meter be programmed correctly
™
using Metercat
. In the Remote component tab in Metercat, be sure that the fol-
lowing options are set:
Port 1 usage is set to internal modem.
■
■
Port 2 usage is set to direct connect.
On the Port 1 Modem tab, enable line sharing (the Enable Line Sharing
■
box is checked).
On the Port 2 Direct Connect tab, the bit rate is set to 9600.
■
The other options can be set as desired. For more information on using Meter-
cat, see the Metercat documentation.
Metercat
The A3 ALPHA meter/collector requires Elster Electricity Metercat support soft-
ware release 1.4 or later. Metercat offers the following features:
program development to create user-defined configuration data
■
meter programming to send user-defined configuration data or com-
■
mands to the meter
meter reading to receive data that has been stored by the meter
■
■
diagnostic read including ILC1 option board and LAN status
ability to perform tasks related to replacing a collector
■
EnergyAxis Metering Automation Server
The EnergyAxis Metering Automation Server (MAS) reads meters over telephone
or wireless networks. Using MAS, meter readings can be scheduled or per-
formed on-request from the browser-based user interface. MAS allows all billing
data to be read from the meter; this includes data from the A3 ALPHA meter
and from each REX meter registered with the ILC1 option board. Billing data
from the A3 ALPHA meter includes multi-channel interval data, consumption,
demand, time-of-use registers as well as meter status flags. REX meter data can
be read from the stored data in the collector or on-request by using MAS to
communicate through the collector to the individual REX meter.

schrodingersbox/meter_cat README
This Rails engine makes monitoring the usage history of your Rails environment easier.
It provides meters, similar to the odometer in a car, which can be incremented
when significant actions happen in your app, and are recorded on a daily basis.
Meters are managed in RAM and periodically flushed to DB after a configurable amount of time,
when the calendar day rolls over, or when the process exits.
Some examples of useful meters would be number of users created, number of emails sent, or
other events particular to your application. Even in cases where the equivalent value could be
determined with a count query, it can still be more efficient to look up a set of meter values,
rather than run a bunch of count queries.
Getting Started
-
Add this to your
Gemfile
andbundle install
-
Add this to your
config/routes.rb
mount MeterCat::Engine => '/meter_cat'
-
Install and run migrations
rake meter_cat:install:migrations rake db:migrate db:test:prepare
-
Generate some random data
rake meter_cat:random[my_test,0,100,365]
-
Restart your Rails server
-
Visit http://yourapp/meter_cat in a browser for an HTML meter report
Configuration
All configuration should go in config/initializers/meter_cat.rb
.
MeterCat.configure do |config|
config.layout = 'meters'
config.expiration = 60
config.ratio( :failed_to_create_ratio, :login_failed, :user_created )
config.percentage( :failed_to_create_percentage, :login_failed, :user_created )
config.sum( :failed_plus_create, [ :login_failed, :user_created ] )
config.to = 'ops@schrodingersbox.com'
config.from = 'ops@schrodingersbox.com'
config.subject = "#{Rails.env.upcase} MeterCat Report"
config.mail_days = 7
config.authenticate_with do
warden.authenticate! scope: :user
end
config.authorize_with do
redirect_to main_app.root_path unless current_user.try(:admin?)
end
end
How To
Increment A Meter
The easiest way is to call MeterCat.add
.
MeterCat.add( :any_name_you_like )
You can also optionally pass a value and date.
MeterCat.add( :any_name_you_like, value = 1, created_on = Date.today )
Set A Meter
The easiest way is to call MeterCat.set
.
MeterCat.set( :any_name_you_like )
You can also optionally pass a value and date.
MeterCat.set( :any_name_you_like, value = 1, created_on = Date.today )
This is useful where you want to record a single value for the day, such as from a daily cron job.
Add Calculated Values
Calculated values (ratios, percentages, and sums) can be defined in config/initializers/meter_cat.rb
MeterCat.configure do |config|
config.ratio( :failed_to_create_ratio, :login_failed, :user_created )
config.percentage( :failed_to_create_percentage, :login_failed, :user_created )
config.sum( :failed_plus_create, [ :login_failed, :user_created ] )
end
Generate Development Data
rake meter_cat:random[name, min, max, days]
can be used to generate random data for development.
The arguments are defined as follows:
- name = String, Any string up to 64 characters long
- min = Integer, Minimum generated value
- max = Integer, Maximum generated value
- days = Integer, Days prior to date to generate values for
e.g. The following command will generate data for :my_test
with value between 0 and 100 for the last year.
rake meter_cat:random[my_test,0,100,365]
Configure Email Settings
Create or add to config/initializers/meter_cat.rb
MeterCat.configure do |config|
config.to = 'ops@schrodingersbox.com'
config.from = 'ops@schrodingersbox.com'
config.subject = "#{Rails.env.upcase} MeterCat Report"
end
Email A Meter Report
You can email a meter report using rake:
You can email a meter report in code:
Require authentication
Create or add to config/initializers/meter_cat.rb
MeterCat.configure do |config|
config.authenticate_with do
warden.authenticate! scope: :user
end
end
Require authorization
Create or add to config/initializers/meter_cat.rb
MeterCat.configure do |config|
config.authorize_with do
redirect_to main_app.root_path unless current_user.try(:admin?)
end
end
Apply a custom layout
Create or add to config/initializers/meter_cat.rb
MeterCat.configure do |config|
config.layout = 'admin'
end
