There are a number of options to automate old manual beld winder but they all use their own communication systems or via RF. One example Rollotron https://www.amazon.de/Rademacher-14234519-RolloTron-Standard-ultraweiß/dp/B0085IEHF8/ref=sr_1_2?ie=UTF8&qid=1483611345&sr=8-2&keywords=rollotron
This would save a lot of effort and time trying to automate my existent roller.
Any experience integrating this with ST?
