EzWand is a cheap powered blinds option.

I bought EzWand because they were the cheapest powered blinds solution I could find. I wasn’t sure if they could be made to work with openHAB2, but now i know they can be so I thought I’d share the knowledge. I hope it helps someone.
To remote control the blinds from OH2, an RF controller is needed. I’m using the Broadlink RM2 (also known as RM Pro and Pro Plus, which will also control IR devices), this one:

Using the e-control app that is used to (natively) control the RM2, update the firmware to the latest version (earlier versions are reported to have some RF issues).
Install the Broadlink binding for OH2. See this topic for details:
(don’t forget to also install the ‘map’ transform).
I had no luck capturing RF codes that work via the capture method described in that topic, but Cato (who created the binding) kindly extracted codes from the e-control app (that i’d captured with the e-control app) with an available python script.
The codes to use in your broadlink.map file are below (hopefully the same codes will work for other users). Note that the RM2_BLINDS_INIT button is the ‘1’ button on the remote (to control just-one blind); if you want to control more blinds, you’ll need to capture the relevant button in the e-control app and then export it via that python script.

My thanks to Cato for his big efforts to get this working.
