iNode Energy Meter is a wireless energy monitor with built-in memory where the results are saved, even every 1 minute. It is designed primarily for home automation. Analysis of daily consumption may help reduce the cost of electricity consumption by choosing better matched fares and changing the habits of users.
Measured energy counters: minute and total are broadcasted (live usage monitoring) with a period of 0.32 to 10 seconds (can be set using iNodeSetup.exe).
Available in two versions: with photo detector element (electrical energy meters), magnetic field sensor or reflective one (for water meters).
The iNode Energy Meter can be used in Home Automation to work with existing elements. You can use for this miniature computer Raspberry Pi 2 or Pi 3 running the script in Python (iNode-LAN) or Bash (BlueZ and BT4.0 USB adapter). Running on a Raspberry Pi 2 or Pi 3 Python or Bash script (easy to modify only in a text editor because it does not require compilation) receives the data and analyse them. It can send them further to virtual sensors of Domoticz Home Automation System or to the ThingSpeak.com collection of data and their visualization. Both Domoticz and ThingSpeak are free, while the sample script is available for download on http://support.inode.pl/ (user: inode without a password).
