I understand your fear, I spent quite some time researching options. At the end I found company from Sweden that sells exactly what I needed. Motor that can be installed inside ikea/kirsch/jysk shades, power supply, roller shutter that works with them, and this nice button remote that works “ok”.
It costed me around 150e per window (some windows are connected together, then it is a bit cheaper as shutter and button are shared). And it is just to hook it up, calibrate the motor (this takes some time to be honest). Also, latest update on the binding broke something so actual state is not reported correctly. I am waiting for the next openhab release to see if it is better.
In my case, it is important to have roller shutter that can change polarity on two cables (see the link down for details of what I have), motor that has only two cables and goes up/down based on polarity on cables. Motor has calibration option, but I think calibration could be done with the roller shutter as well. Honestly, I would not have ordered it if it was not packed in a package and working combination not demonstrated on the website.
This is a Smart Color Button - Philio. It is wireless, gyroscope based “button” that works directly with shutter/motor itself (so if openhab is offline, shades work, which is a must I think). They say battery lasts for 6months, but it is usb rechargeable, so not a biggie. It reports battery level to the controller so that is a plus.
As far as WAF goes, it is wireless and looks nice so that is a plus, but to use it it is a bit, well… different to operate as it is just held by magnet on the holder/wall and has no rotation limitats, so it is not 100% intuitive for first time use as you just turn it and then nothing happens, then you have to wait almost 2s for it to settle and send new position to the shades, and one cannot change direction (at least I didn’t find how) so “left” might be counter intuitive as if shades are open or closed, so it is a bit fiddly to operate. Also it has a tolerance rotation, meaning that fine adjustments for the shades are a bit hit and miss, so… Also by pressing the button, shades goes down and button turns it self off and doesn’t react to rotation… very annoying
But I am hoping that blinds will mostly work automatically so that would not matter that much. And I didn’t find some much better remote dimmer-like controllers for the blinds, so… it works for now. Easy to replace later
