Data can now be logged to Emoncms runnning on the emonPi’s local server, data will be saved to the Raspberry Pi’s SD card.
For application specific input processing see:
- Login to Local Emoncms http://emonpi/ (or local IP address)
- Navigate to
Setup > Inputs
You should now see an updating input list of connected nodes (e.g emonPi, emonTx, emonTH) and they keys (e.g. power1, power2 etc.) together with the last received value. If you do not, see Setup > Troubleshooting.
Input data is not saved to disk. To save an input Emoncms Input Processing is used to log an input to a Feed. Feed data is then logged persistantly to disk. To log an Input to a Feed:
- Click on the
Input Config Spannernext to the input you wish to log to a Feed:
- Process List setup box will open
- Choose required Input Process e.g
Log to Feed
- Create a new feed giving it a name e.g.
useor log to an existing feed *
- Select the default
- Select a logging interval e.g.
10sfor emonTx/emonpi or
- Click add to
Addto add that input process
If logging a
Power value input you will also want to create a corresponding KWh Feed. This is done by adding another input process:
Power to KWhInput Process
- Create a new KWh feed e.g.
- Once required input processes have been added click
Changed, Press to Save
Closethe Input List window
- The Inputs page should now display the active input processes in the
- Navigate to
Setup > Feeds
- Updating feeds should now be visible
- To view the feed data click the
- This will open
- Multiple feeds can be overlayed on the same graph by checking the boxes on the right hand side
- To view daily data see Emoncms > Daily KWh.
Note: no data will be visible immediately. Wait a few hours to build up some data before trying to view a feed.
* Using standard feed names such as
import_kwh (case sensitive) will automate the setup of MyElectric, MySolar PV and Android app dashboards. See Setup > Dashboards and Home Energy and Solar PV applications pages for more info.
** IMPORTANT: Feed interval logging time should not be less (faster) then the default node update rate. Choosing a longer (slower) update rate is fine and will conserve disk space:
|Node||Max Update Rate|
We recommend making regular backups of local data. See Setup > Import/Backup.
