From Logitech Harmony to Broadlink

[RueDesButtes]

Hello,
Domoticz V4.9700 / Raspbian / RPI3
I own a logitech Harmony and a RM Pro, both are recognized in Domoticz,
In Logitech, I have a special button that ON/OFF a Benq Projector, this button is not shown in domoticz, only the activities are.
I would like to send a command to a RM device, when the Benq ON is pushed, and a command to another RM device when BenQ OFF is pushed.

Can someone give me some advice.

Thanks
