1. for the hardware
• a big memory capacity for storage all the data during several months (for 10’/15’, hours and day average consumption data) and several years (for week, month and year average consumption data)
• digital inputs used for counting pulses or read status of circuit breakers or acquire tariff periods
• digital outputs for load shedding to act on reduction of energy consumption
• analog inputs if we want to analyse consumption with output information like temperature.

2. for the configuration
A simple configuration tool to set-up the installation easily. The main functionalities of this tool are:
• enter a name for each measurement channel
• enter energy type (water, gas, heat, …)
• enter weight of one pulse
• choose several recording periods (10’, 15’, 1h,1w,1m…)
• generate dashboards, reports and mimics diagrams

3. for the software
• must be a web server
• can generate CSV files of values from the database 10’ or 15’, hour, day, week, month and year records consumption
• can generate curves for analyses
• offer the possibility to download CSV data files for Excel analysis.

I know currently a RTU called iRIO or RIO that has these features and I am interested to know if there are other devices of this type in the market.
