Feed processes

Hi again!

I'm feeling quit dumb, everyday opening new help topics... This time my doubts are with the feed process sequence...

What happens in each process and what happens after the process? Can you explain me what happen in this sequences (the input data is accumulated kWh; for tests purposes I'm using emoncms.org in order to have the full emoncms installation working properly)?

 

Sequence 1:

- Log to feed (stores the accumulated kWh)

- kWh to power (convert the accumulated kWh in instantaneous power W)

- kWh to kWh/d (does it uses the accumulated kWh or uses the power from previous process? And what is the output exactly?)

 

Sequence 2:

- Log to feed (stores the accumulated kWh)

- x 0.001

- kWh to power (convert the accumulated kWh in instantaneous power kW)

- x 1000

- Power to kWh (converts the instantaneous power W in accumulated kWh)

- kWh to kWh/d (converts accumulated kWh in kWh/d?)

 

 

How to use Histogram and what does it do exactly?

What is Wh increments do kWh/d?

What does the Accumulator do? And Rate of Change?

What does the +feed -feed /feed *feed do? How does it work?

 

I tryed to searched for this answers in the forum and in the emoncms documentation but couldn't find anything...

 

 

Edit: I've created a new input to add the sum of the 2 gas meters (boilers and kitchen). This new input don't receive any data, I only want to use it to do some feed processes. I've attached a .jpg with the process feed. Those 2 +input are updated when the respective inputs receive data (every 5 minutes in this case). But the rest of the processes aren't updating.
