New functionality: method to separate out night / day usage over time. Could you please comment on possibility of adding a method to total kWh for night and Day usage. It would be a useful tool e.g. calculating benefit of cheap night rate (good for pocket and environment). I'm not sure where to start any ideas or guidance??
That would be useful indeed. I try to run dishwasher and washingmachine at night for that reason and would be nice to assess the savings.
I am working on this not quite finished yet
It separates the E7 import usage period from the rest of the day
Let me know if you are interested and I will post the code (not sure how to do this)
Yes please send code to firstname.lastname@example.org
Hello Ian, great work! can you add it as an attachment here? Click File Attachments below the editor box here, then browse and upload.
I have attached my latest version of my revised display
It now shows the current days totals and Yesterdays totals
Attached is my code
Not sure if the attachment worked on the previous post
Nice! I'm considering starting an emonGLCD gallery page with screenshots and code for different customizations. That way users can mix-and-match bit's of emonGLCD code to help customize their own displays. Would you mind if I included your emonGLCD photo and code in the gallery?
No problems with that
I will continue to post up my updates
Looks great. However I was looking for something similar to kWh/d except breaking it further down to peak and off peak hours, then to present as bargraph. Any pointers or ideas welcome.
The E7 number is Off Peak rate usage and Import is Peak rate usage - I suppose I should have given the Import line a better name - I will change this on the next version.
The current version only caters for Economy Seven times after midnight
Should be easy to change so that it can caters for off peak times that spans midnight. My off peak times are on a label on my meter - the times vary by region in the UK.
Hi Ian, Thanks for reply, your code naming convention and code explanations look fine even for a novice like me, I will definitely use this in near future.
However now I'm investigating how best to get similar information from data collected via the standard emontx by querying the mysql database directly.
I may be missing something but I'm hoping it will be easy enough to query database and retrieve kW used for peak and off peak. Very similar to kWh/d on bargraph except peak/ off-peak would be side by side instead on over 24 hours.
