![]() ![]() ![]() Turned out, this library was not compatible with my ARM-based Due board. (NOTE: JeeLink was later replaced with JeeNodeUSBĪs a starting point, I used a great port of RFM12B library to C++ by Felix of For this I purchased a couple of RFM12B modules and a JeeLink from JeeLabs shop: The next logical step was to test wireless communication between this sensor controller and whatever the base might be. So, instead I decided that I’d need faster processor, more analog inputs and 12-bit ADC resolution. EmonTx has only three current probe inputs with 10-bit resolution. This could be the result of limited measurement speed and/or limited processing power or the Arduino Uno -based hardware. When I removed the plastic cover, I noticed that there is quite a lot of space under it, so I hoped I could nicely fit all required hardware inside and hide it from view.Īs far as I could see, the original EmonTx approach from OpenEnergyMonitor was to measure current at the input to the breakers. This way I could have detailed power data as well as compute total house consumption. I thought that it would be nice to monitor these 10 output lines individually and independently. To begin with, I looked at the electrical fuse box in my apartment and noticed that I have 10 or so circuit breakers leading to separate electrical house circuits. Software: Arduino IDE, EmonLib and RFM12B library by LowPowerLab.UPDATE: Raspberry Pi has now been replaced with Ubuntu NAS and Backup Server.Hardware based on Arduino and Raspberry Pi platforms.Concept based on OpenEnergyMonitor project.UPDATE: Temperature/Pressure sensors added: Additional Sensors for Home Energy Monitor.Eventually include data from other sensors, like temperature, pressure, humidity, motion, light, security, etc.Monitor, archive and analyze energy consumption in the house.
