I came across OpenEnergyMonitor at the fullychargedlive show.
I have been looking to build a data logger from an arduino and with limited time never got to a finished project. I have a fair amount of experience with electronic design and manufacture and coding is a hobby.
I have to say what these have achieved is very impressive and i want to buy in!
- My primary goal is to datalog my ground source heat pump system. I have a lot of experience in the design and installation of heat pumps if anyone needs advice.
Items i wish to log:
*Ground Flow Temp
*Ground Rtn Temp
*Heating Flow Temp
*Heating Rtn Temp
*Heat pump kW (Have bad experience of clamp meters giving very large deviations without a powerfactor, so i already have a energy meter with a pulse output installed, I see this system can use a AC-AC adaptor to correct the power factor, is this accurate or should i use the pulse from my energy meter?)
*Heat meter (Kamstrup, Pulse or Modbus)
I notice the HeatPump project that had hardware specifically for the above is not active in the shop any more.
Is the Heatpump project running?
Can the EmonPi handle the above?
On the web interface i would like to display custom calculations such as COP?
Is there a neat way to measure copper pipe temperatures with the supplied thermocouples?
Can the pulse from my meter be used in place of the light pulse sensor input?
Must you have a clamp sensor to calculate COP, or can the light / pulse input from a meter be used over time?
Appreciate any advice!
