I've got some problem with blinds with Eve and Homebridge on a rbpi3 with SDImage and running the latest beta:
I'm using fibaro roller shutter 2, configured in domoticz as blinds with position and they works fine (they are recognized as ON/OFF but should be replaced with CLOSE/OPEN but it's not a big deal)
in Homebridge they are recognized as normal switches with no position.
I've read that switchtypeval should be set to 13... but unfortunately I'm unclear.... WHERE to do that!
