Here is the code to read the Open Energy Monitor V3.4 with a RFM69 module connected directly to the Raspberry Pi. It is interrupt based and does not ask for a lot of processing power. A few Python modules need to be preinstalled and the program needs to be run in sudo mode because it accesses the ...

Can't get the RFM12 chip to work on the Pi B (without going to C code). It reads a few bytes and the the rest of the bytes get overwritten before they can be read. Not sure if the faster Pi B 2 would perform better. My Beagle Bone Black has no problems. But I moved on and I now own a RFM69 chip ...

Ok update so far, hooked up RFM12B chip to Raspberry Pi. You are missing the Chip Enable 0 line in your diagram! It needs to be hooked up to pin 24. And the MOSI does go to SDI on the RFM12B module. Ok, so far this works but then the trouble starts. If I do a print data I get a couple of bytes fine ...

Yes lovely those MISO and MOSI terminology. Master Input Slave Output=MISO I would say goes to SDO on the RFM12B and MOSI then to SDI (Reverse from what you wrote!). I am not using the IRQ line from the chip. I found that it was to slow (Python couldnt keep up with it). That is the reason why I want ...

Okey thanks! Shall try the Open Energy Monitor, again later in this week. I think it's a problem with quote messages, the location disappear when I use it. Dutch is little hard to understand! for a Swedish guy :), but thank's anyway. You can always use google translate. :D I have a Pi B laying ...

I've got also a CC 128 managing 4 devices. With a Perl script, I've got the watt values, but the Kwh values are not updated because I only read the xml live values not the summarized ones. Also, the virtual device is not in the good type, i would like to have a type = Usage, Electric but it's not ...

Hi! I have setup a Raspberry pi B+ with latest domoticz image. Raspberry Pi Details: Type: Model B+, Revision: 1.2, Memory: 512MB ls /dev/spidev* /dev/spidev0.0 /dev/spidev0.1 udo raspi-config Advance option SPI Enable Serial enable I2c enable sudo apt-get install python-rpi.gpio python-dev sudo ...

Just wondering what CTs you went with? I looked at Open Energy Monitor but as you said they are setup more for single phase or 3 phase. I couldn't find a CT for 100 amp per phase 2 phase service like we have here in North America. I used the Aeon labs HEM through zwave but I am finding the kw ...

Hi! Nice project! I have also an energy monitor V3. My first thoughts was to use the monitor separately on a dedicated Raspberry Pi apart from Domoticz, but then I saw your nice project. My question is? Is it hard to adapt your script to Raspberry Pi ? I'm not a Python programmer :D No the python ...

Ok I got a bit futher with this. I created a Python Scripts that will read the data directly from a RFM12B chip into my BeagleBoneBlack. I am not using the nIRQ line from the chip but use polling which makes the BBB very busy. But it does give me data so I am very pleased. The origional project uses ...

I think you are almost there. Did you create the 2 devices needed in Domoticz? They are not created on their own. And when you create them you will get a new IDX value, you will have to replace the 2 IDX values in the script with yours..Then it should update..Keep checking back here I might modify ...

what type off cable do you use? when i search the internet for a usb to apc cable, they are very expensive My APC ES-650 came with the cable. Check this link http://pinoutsguide.com/UPS/apc_usb_cable_pinout.shtml Looks like it is a RJ50 but the crimper for this might not be easy to find. Greetings ...

Will this script also shutdown the Pi when running on battery power? Or do I have to add Some values or perhaps with blockly? I modified the script to do a shutdown -h when the battery power is down to 10% and the UPS in ONBATT. It requires to make shutdown to work without password, the ...

The APC (Brand) is a battery backup (UPS), most of them have a USB cable that you can plug into the device that run Domoticz. The voltage sensor is build into the APC. So you will be reading the line voltage that the UPS is measuring....

I made one too, this one is in Python script for whoever wants it, now with auto shutdown when battery power is down to 10% #!/usr/bin/python # # Script to read APC battery backups settings and voltages. # And publish these to domoticz software. # # (C)reated by Rtm-soft Jan 2015 # # This code is ...

Hi, Is there anyone working on the Open Energy Monitor? I ordered this energy monitor V3 with 4 CTs. I want to make my own driver for the RFM12b so that I dont need to interface with the RFM12Pi which looks like an extra step to me. Why can't a 600 Mhz 32 bit processor (Or 1000 Mhz Beagle Bone Black ...

Looking forward to see your lua script! I tried the Lua script but I failed in opening the com port, so then I made something REALLY simple in Python. I am running this script on my Beagle Bone Back with Domoticz installed. All that needs to be done is to create two Virtual Sensors in Hardware. One ...

Hello everyone, A friend of my has the same device. It should not be hard to program a driver in LUA..So I will keep you posted on the progress..
