I strongly recommend move away from this package
The work done by @lprhodes it's awesome, but apparently he couldn't continue with the project. I know life sometimes could be very hard, but the lack of updates in a important plugin like this, could delay the progress.

I as a user face some problems with my Broadlink **62be**, **6539** and the plugin. My problem was solve instantly with the fork made by @kiwi-cam, which include more button options.

Please, don't consider this as some way to create fights or comparison between which is better or not, it's only to be practical  and give a hint in case you see a message for the devices mentioned to raise issue here.

Follow the fork
