Issue in connecting EdiMax Smart Plug

Hi

I am unable to establish connection between EDImax plug and Openhab.

Here are the set of steps I followed

Step 1:Downloaded the binding [org.openhab.binding.edimax_1.9.0.201607291201.jar] from a github site into /opt/openhab2/conf/addons folder.

Step 2: Verified binding

openhab> bundle:list | grep Edi

Step 3: created an item file

Switch EdimaxSimple {edimax="801F02FA6BB5:4711"}
Number EdimaxCurrent "Current [%.1f]" {edimax="801F02FA6BB5:4711:CURRENT"}
Number EdimaxPower "Power [%.1f]" {edimax="801F02FA6BB5:4711:POWER"}

Step 4:
Check the status of item file in openhab console but it seems it’s not getting loaded -getting message “no item found”

openhab> items list *Edi*
No item found for this pattern.

Step 5: created a site map file and also included the EDImax binding text in addon.cfg file.

Frame label= "Power Plugin" { 
       Switch item= EdimaxSimple 
       Text item= EdimaxCurrent icon="battery-50"
       Text item= EdimaxPower icon="battery-50"
 }
****** addons.cfg file***
legacy = true

binding =mqtt,mqtt1,edimax 

Please ref to the screen - there is not data coming out from EDIMax plug.

Just FYI, I am able to control the plug from the app on my phone.

Appreciate your help.

I just managed to get them working again by downgrading the firmware described here: https://github.com/mwittig/edimax-smartplug/blob/master/Downgrade.md
