Lechacal board configuration, emonhub

georgel · 2019-01-02T15:44:57.356Z

Also going to step in here and ask for help.

I got the Lechacal boards, if I do a serial retrieve i can see data coming back… although the numbers does not look correct atm, trying to check this… (attaching a text output and python script used to retrieve)

But if I go inputs I don’t see any. Any advise

Could it be that because I don’t have a LCD connected the rest of the stack is failing?

Any ideas how i now configure the base emonpi images / devices/input to be able to show these.
Also want to configure a kW/h line.

Hello @georgel

I dont think this is related to the original thread. The LCD not being present should be fine.
It sounds like a emonhub configuration issue to me. OpenEnergyMonitor hardware uses emonhub as the intermediary between the serial port and emoncms. Emonhub decodes the data packet which is usually in the RFM format and then forwards that data on to emoncms.

It looks like the Lechacal board provides a CSV output. You can use the direct serial interfacer for this. There is an example of the configuration here: emonhub/conf/interfacer_examples/directserial at emon-pi · openenergymonitor/emonhub · GitHub
