This is just save the next guy/gal who might have Hunter Douglas powerrise blinds that they might want to automate with OpenHab a half day. I used a sparkfun ESP8266Thing to create an IR remote that I can control with Openhab over wifi. The challenging part was all of the hex codes I could find on the internet were wrong and the arduino decoder library I tried got it wrong (same as published one as far as I could tell). I got out my oscilloscope and brute forced it. Here is the raw data in decimal (ESP8266 via Arduino IDE). It basically repeats the same sequence of 5 pairs for 300ms.
