Devices ON OFF in a reaction

Hi All,

I have 4 buttons that control 4 devices.

I want only 1 button to be on at a time, meaning that one device is ON and the 3 others are OFF.

To do that, I tried using a Reaction on the Move button to send a 0 on all the other Buttons.

but the device does not react.

So my question is, how to set ON/OFF a device in a reaction action

Thanks
