Hi
So I've been tinking with emoncms for a while now.
Question for emoncms developers - why don't input processes, actually return the result of processing back? Like they are supposed to?
I've created an accumulator_hourly function, that basically accumulates data on an hourly basis.
The plan was to feed in kwh, to this, to then get an idea of power user per hour ---
I was always getting strange results. Doing some debugging, I found this, in power_to_kwh - it always returns power?
ie:
public function power_to_kwh($feedid, $time_now, $value)
{
$new_kwh = 0;
...$this->feed->insert_data($feedid, $time_now, $time_now, $new_kwh);
return $value
I change it to -
$this->feed->insert_data($feedid, $time_now, $time_now, $new_kwh);
return $new_kwh;
Am i missing something?

Re: input process return value not the real value?
They are inconsistent. The use cases are complex. Suppose you want to log to two accumulators with the second covered by a logic condition - it's not possible because the first accumulator returns the total value, so you can't add it to the second (without a bit of fancy footwork). At the same time, if the accumulator didn't return the new total, it wouldn't be possible to feed it into a daily aggregate feed.
