Pulse to Watt & kWh with EMONCMS 9.2 on EMONPI

Submitted by fammann on Sat, 19/12/2015 - 18:46

Hallo

somehow emoncms on emonPi does not seem to have all "process" types available as with "emoncms.org". Does anybody know how I can easily process Pulse information from a power meter? I get 1 pulse per Wh.

I found some explanations how to process pulse kWh information on emoncms.org which seems to work well. But on emoncms for emonPi I do not seem to have same "process" types available. Maybe there is a much easier way using a specific visualization tool?

Ideally, I would like to get "current Power in Watt" and "kWh/day" displayed in a dashboard.

Any help very appreciated

See optical pulse count documentation for how to log pulse data to feed on emonPi :

Thanks - not sure why I did not find this... I actually added Power calculation to the emonpi Arduino sketch "emponPi_Interrupt_Pulse" and added an additional variable "emonpi.pulsePower" to node 5. This way I can not only get kWh but also Watt displayed in CMS

Maybe you could add this extension to the official Arduino sketch?
