I am trying to show the daily COP and weekly COP for my HP monitoring dashboard:
I realised however that I can only use feed values on the dashboard so I need to do the processing on the feeds first. However, I only have access to emoncms.org and I don’t think I am able to create virtual feeds. Therefore, I had a few questions about how the feed processes work:
If I apply multiple processes to an input and use log to feed. Does that mean the following step has the input raw value again? eg I use log to feed, then I multiply that value by 0.001 and then use log to feed again.
How can I use the power to kWh/d for a pulse reading? Is there another way to create a daily cumulative feed?
This is what I have done so far:
If I want to divide a feed by another feed (i.e., the daily heat by the daily electricity use) how can I use the processes to achieve this? This is what I have tried but the power to kWh/d output is not passed to the next step…(hence why is diving the raw value by the feed i think). I have a similar issue if I try to do COP of the instantaneous feeds (the electricity value has to be Wh since is a pulse meter reading and if i use power to Wh for the heat reading it is not passed on to the next step therefore I can’t divide it by the electricity feed).
Thanks a lot in advance!
