Hi David,

Unfortunately it is not possible to simulate hardware devices. See:

> [@Simulation error - please help](https://forum.xod.io/t/simulation-error-please-help/3911/4):
>
> You can’t simulate extra hardware like buttons, LCD, LED, or sensors. These need replaced with tweak or watch nodes or run on actual hardware. You can use debug when running on hardware to combine tweak/watch nodes with extra hardware.
