Llama not recognising wireless charging event

[itm]

I want to use Llama to silence my Galaxy S4 when I put it on the Qi wireless charger overnight. The problem is that, even though the phone displays a message when it goes into wireless charging mode, Llama doesn't triggers its own wireless charging event.
Does anyone know of a similar app that will recognise the wireless charging event on the S4 and put the phone into Silent mode?
