Filter values from sensor

Third party integrations Node-RED
1

Hi,

I am pulling data from an Alpha ESS inverter, using a custom node in Node Red. The values are polled by the node and populate sensors which i display in HA.

What I want to do however is create 2 new sensors, which record wattage (imported) and wattage (exported). This is represented by the node as either a positive value (200) or a negative value (-200). This part works as it should.

The issue is that the “less than” value when used in HA will work backwards, it shows as a negative value as the inverter has 1 CT. I would like to take this “less than” value and change it to a positive number, then, if inverter is exporting, the import should send 0 to the import sensor. If the inverter is importing, it should be send 0 to the export sensor.

Here is what I have so far:

Use a function node:

if(msg.payload.battery.load > 0){

    msg.payload.battery.load = Math.abs(msg.payload.battery.load);
    return [null, msg];
}

If I understand correctly this will set the other sensor to zero, depending on import/export. Also change the negative value to positive.

Thanks, this works! However when the inverter goes from discharging to charging, it does not set the value of the other sensor back to 0, it remains at the last value.

When the inverter switches to charge mode, the import sensor needs to read 0 (the same the other way around).

There was an issue with the change of negative to positive, on the wrong sensor - swapped and now works perfectly! Thanks.
