Hi everyone, wanted to let you know my solution to having Alexa control the blinds without the expensive RFX433. All you need is the Broadlink RM PRO+ available for around $50 US - Using the application IHC add the blinds as an custom appliance and learn the radio signal using the remote that controls the blinds/curtains and then create a scene - one scene to open and one scene to close. Log into Alexa and add the Broadlink skill and link your accounts. The tell Alexa to discover - she will find the scenes created in the IHC app. Then in the Alexa app create two routines - one to open and one to close blinds and link these routines to the newly added scenes from IHC.
Job done - now just say “Alexa, open bedroom blind” for example and she will run the scene.
Hope this makes sense. Its far easier than trying to get the RFX to work.
