I am using Zigbee.
I have the Z-Wave version, not really happy TBH… If others can give their input in regards to the behavior I’m seeing here I’d really appreaciate it! Smartwings Z-Wave roller blinds lag/erratic behaviors
Personally I had issues with the zigbee versions with ZHA, even with 5 hardwired repeaters less than 6ft from the blinds. Blinds kept becoming unresponsive. After contacting support, they agreed to let me pay the difference for zwave motors. Replacement was easy and they have been rock solid. Support had no idea why the zigbee kept dropping off. They were the only zigbee devices I had problems with so I’m pretty sure it isn’t my network. For what it is worth!
