Wrong scene value sent by Aeotec WallMote Quad zw129

I’ve noticed on occasion that when pressing a particular button on one of my wall mote quads, there is no response from the target device. I added a log statement to the associated rule and in the logs, not only do I see the wrong value sent (I get 255), but every tap of that button is sent twice:

Here is the rule:

 rule "Desk Mote received update"
when
Item desk_scene received update
then
val sceneval = desk_scene.state
logInfo("desk", sceneval.toString)
 if(sceneval == 2.0 ){
	val desklightstate = Desk_Light_Switch.state

	if(desklightstate  == ON){
         Desk_Light_Switch.sendCommand(OFF)
         Desk_Light_Switch.postUpdate(OFF)
}
else{
    Desk_Light_Switch.sendCommand(ON)
    Desk_Light_Switch.postUpdate(ON)
}
end

Here is the log output:
First tap:

2018-12-06 01:12:28.967 [INFO ] [.eclipse.smarthome.model.script.desk] - 255
2018-12-06 01:12:29.738 [INFO ] [.eclipse.smarthome.model.script.desk] - 255

Second tap:

2018-12-06 01:12:45.311 [INFO ] [.eclipse.smarthome.model.script.desk] - 2.0
2018-12-06 01:12:45.337 [INFO ] [.eclipse.smarthome.model.script.desk] - 0  

This time is even stranger. Instead of repeating 2.0, I got a 0.

After another press or two, the correct value is sent and the target device behaves correctly. So what might be the problem?
Thanks

Try using this rule

rule "Desk Mote received update"
when
Item desk_scene received update
then
val sceneval = desk_scene.state as Number
logInfo("desk", sceneval.toString)
 if(sceneval == 2.0 ){
	val desklightstate = Desk_Light_Switch.state

	if(desklightstate  == ON){
         Desk_Light_Switch.sendCommand(OFF)
}
else{
    Desk_Light_Switch.sendCommand(ON)
}
end

Thanks for the reply, but I still get 255. I’m going to open a ticket with Aeotec about this, this device worked flawlessly for over a year before this happened.
