I tried becky's rm bridge but got stuck at the learning devices part. In my opinion, rm tasker is more convenient if your setup involves the rm pro and tc2 light switches as the controls can be imported from broadlink's e-control app into rm tasker right in the app itself.
The current version of rm tasker in play store is 1.6.8. It's stable and I've had it running for almost a week without problems and alexa was able to find the devices without re-discovering.
Also, the app developer changed his codes such that devices appear as philips hue lights and there's no longer a limit of 25 devices.
Just to clarify, I've set my android TV box never to go to sleep.
