Activate 3 dump load when I export 500w 1000w and 1500w

Hello

I would like to activate 3 dump load when I export 500w 1000w and 1500w

is it possible? I have read everything I have been able to find without any luck. I have an ESS with a MultiPlus2 48/3000/35/32 and a Cerbo GX and mains connected 2500w solar system.

Regards Jens

I guess with Node-RED you could use the two relays of the Cerbo for that.

Another option would be to export the feed-in / grid-export data via modbus from the cerbo.
Afterwards you are free to choose a device / smart-home system / etc. of your choice and implement the mechanics there.
