Dupline Mastergenerator G3800 X015 modbus / switch integration

Configuration

Hi,

I have a Dupline Mastergenerator G3800 X015 with modbus support. I’m able to create a switch, which I can turn on/off.

Below you will find a setup of all 128 channels as a switch with verification of whether the swich is off/on.

This way you can “upgrade” your old dupline system to a smart home

You need a USB to serial RS232 cable and connect it in com1 on the master generator.

Hope this helps anyone with an old dupline G3800 X015 Mastergenerator.
