Linky Shield for Arduino

Description

This shield plugs into any Arduino Uno shaped board and allows you to read real-time information provided through the official consumer-side Télé-Information Client (TIC) output of the french Linky electricity meters. That information, refreshed approximately every 10 seconds includes:

• Power (in W)
• Current (in A) for each phase
• Accumulated consumption (in Wh)
• Advance notice for EJP Rate (Préavis)
• Pricing for EJP Rate (Heures Normales, Heures Pointe Mobile)
• Pricing for HC Rate (Heures Pleines, Heures Creuses)
• Pricing for Tempo rate (Bleu, Blanc ou Rouge)
• Tomorrow's color for Tempo Rate (Bleu, Blanc ou Rouge)

Features

• Example firmware provided in the links below
• Supports long distances
• Screw terminal connector to easily connect cables from your Linky meter
• Doesn't use any gpio or interrupt, only the I2C pins
• Led to display activity
• Comes with headers assembled, so you don't have anything to solder

Use cases

• Home automation, where meter is located too far away for wireless sensors
• Advanced control of power hungry home appliances (water heater) when using the Tempo option
