Auto blinds and SONOFF

Very happy with my RoomieRemote set up but keen to finish the cinema room. I have two questions:

  1. Blinds threads seem quiet for a while. Which are the best to integrate in? Ideally they would be rechargeable and Wi-fi but open to ideas. I currently have an iFlex IR blaster so anything that would work with that would be ideal
  2. I’ve used SONOFF devices throughout the house which use the eWeLink app - are there any options for connecting? Otherwise what is best for replacing them that integrates in to RR?

Many thanks, in advance!
