The hardware from openenergymonitor

hardware's Introduction

OpenEnergyMonitor Hardware

OpenEnergyMonitor hardware is open source hardware. This github repository hosts all the Eagle schematic and board files for the hardware units in addition to images for quick access.

Update: most hardware designs have now been moved to dedicated repos, see individual folders

hardware's Issues

break out the Arduino A6 & A7

hi , first of all apologized to draw issue for my question , however I was wondering why didn't you break out the A6 & A7 pin for extra V or I measurements, I thought with reserve the A4 & A5 for I2c ,still have 6 Analogue pin for measuring 3*2 V-I line
actually base on your hardware design I made pre design schematic using ESP as communication control center with one Arduino connected as I2c slave, I really appreciated if I have your comments or idea about that

Components value

Could you please tell me what are the values of following components, it's missing in eagle drawing:

L1
D2, D3, D4, D5, D6

Request: extract gpio i2c or RTC integrate

it's possible to extract the bus i2c (pin 4 and 6) from gpio of the raspberry pi?
are useful for connecting a RTC or a display.
or maybe integrate an RTC with a small battery type CR1220 ??
Great job!!

Internet of Things - Bill of Rights

Big fan of the openenergymonitor ecosystem (free software and open hardware), I'm a user and promoter of your software and hardware (in particular for non-tech people who can in that way support your awesome work).

I came across the Internet of Things Bill of Rights initiated by @adafruit
https://github.com/adafruit/iot-bill-of-rights

The project doesn't seem to have moved recently but I was wondering if you thought it might be interesting to associate emoncms/openenergymonitor to such an initiative. I haven't read https://emoncms.org/site/privacy in detail but I think there are similar notions.
