NodeRed Fronius export Limit

Hi Guys

I'm trying to switch my Fronius PV Inverter off when I'm using Generator via NodeRed.
I have used a trigger to pulse every 0.5 sec to send the value 0 to the Fronius "Power Limit" when generator is running. If I don't do this the Fronius keeps delivering PV power to the system and I'm scared that this will damage my Generator.
However how do I stop this trigger after I got a start signal? It keeps setting the Fronius power to 0 even though the generator stopped. I have tried using the payload.reset command as well as payload = 1 command.

Kind Regards,

A slightly lower tech approach.

Run the generator at a slightly higher frequency and that will throttle the fronius automatically.
