Hi all,
I got my second hand FLM V2 I think and I know basics of Raspberry Pi and Node-red.
My setup is this:
A. 1 clamp is on the internal consumption
B. 1 clamp is on the first solar panel convertor
C. 1 clamp is on the second solar panel convertor
In Node-red I did read the FLM with MQTT and it works well.
I made 3 gauges.
1 total internal consumption.
1 sum of the 2 solar convertors
1 Deduction of total consumption - solar convertors.
Now I would like to store the daily data into node-red and here my knowledge stops.
It needs to be with db I think.
Is there here somebody with a working Node-red Flow?
PS: it is not possible to add an image to this post. Sorry
Store for what? Just to display? Then you can dump the data in a graph with the desired timespan and node-red will cache it.
Caveats:
- data lost when node-red restarts
- at the rate the data comes in from Flukso, the graph will become slow to display, so add some filter to reduce the rate
See data in node red dashboard to see daily solar production and consumption of internal circuit.
And even send it to csv.
You may be able to use pvoutput.org

I did it with WWW.EMONCMS.ORG
Works great!
I changed the mqtt output format to a json object (rather than array) and use influxdb and telegraf to store all the outputs. Then use grafana to graph it as I please. Sure it's not node-red but satisfies 'store daily data' requirement.
