bounce material event

[infrafast]

when a switch change state, the state is fired to all listeners which could cause some infinite loop (example: with domoticz, when virtual switch is updated, it all the function "change state" which then fire the event etc...) as a consequence, we only change the state (and hence fire event) if the requested state differs from the current state. This method works, however we observe some "bounce" as the command is still executed a few time s(about 4) in a second .... see below logs

fixed by adding sleep

function setPinState($pin,$state){ global $materials, $options, $pins; sleep(1); if ($state!=getPin($pin)){
