OK here goes. Here is a port of the monitoring part of the Open Energy Monitor - very little needed to be changed. I had an Arduino/Raspberry Pi energy monitor running for a couple of years but the Spark frees me from a long run of wires and gives me more processing power without going to the expens…

Hey great port of the energy monitor for spark core…One request though-- Could you merge the recent changes in the master open enegy monitor code to this branch too…I don’t know how and i might mess up the code… They have made a lot of improvements such as using a low pass filter instead of high pas…

@jiyojolly , thank you for pointing out the new version of the emonlib. I’ve had a quick look at the latest Open Energy monitor code . It does look neater. I’ll update the SparkEmonLib to incorporate the better filter. The dodgiest bit of the code/hardware is the correction for the time difference bet…

This project looks really cool. Nice work. I wrote up a similar project I did a while ago: https://unop.uk/dev/raspberry-pi-electricity-monitor/ I’ve considered doing some direct measurements of the meters with my core but there is no power source in the meter cupboard (ironic I know).

@JSingleton - Brilliant presentation! I also had a problem with local power near the meters and before I bought a Spark I ran a long length of 4 core telephone cable from the meters to an Arduino. The digital ports connected to 2 photoresistors (for generation and general power) and a reed switch (f…

@phec Thanks! The resolution isn’t too bad even with the 7 second sample period. You can still see the inrush current of the compressor on the fridge (although not on every cycle). There is so much more that could be done with sub-second sampling but that’s a lot of data to store so it would need s…

Here is my port of the O.E.M project for Spark. It includes the tinker code so you can feed inputs (with a jumper) with fake data. [image] officeboy/EmonCore EmonCore - Open Energy Monitor All in One for Spark Core/Photon

@officeboy , that is great. The git repository that you refer to has a Spark compatible version of emonlib and I see that you have updated it to keep it in line with the master emon branch. Consequently my gist is now redundant. @jiyojolly please note officeboy and Cinezaster’s excellent contributio…

@phec I thought you did a nice job on your library and a really nice job documenting it, but I just couldn’t bring myself to use it due to the name.

I take your point. All my Spark libraries started with S which made it easy to find them. When I did the emon one I thought oops - but was too pedantic to change the naming scheme.

Thanks…Hey I forked the master code from github and made changes to it to adapt to sparkcore myself…Finally got it working…Saw the @officeboy and Cinezaster github code after I went through hell making changes… Thanks for your input!!
