I bought some of these to add to an existing Neo smart controller with the old 433 MHz RF controlled motors. Those ones are great. This new version is awesome. Control blind down to exact % opening, save favourites, recharge via USB-C, and control with your phone via bluetooth if internet is own down (no need for backup remotes). Super easy to install into a modern roller blind cassette (if you are trying to retrofit into an old roller you would need some engineering know-how) - 5 min job. Paired to phone very easily. It took a lot longer to get pairing to work with the old smart controller (need to change the setup code to SBH20 to get it to work with old and new motors at same time), but i would guess it's super easy with the new controller. Unfortunately if you retrofit into an old controller you don't get the bonus features (battery %, open %, favourites), but still work great.

Connecting to Alexa/Google Assistant is very straightforward and provides instant voice control ("Hey Google, open the XXX blinds"). Note that there is no SmartThings edge driver for these. You can theoretically build your own with the Neo API but i found it easier to create a virtual switch in SmartThings and then use that to drive an automation routine in Google Assistant (e.g. When Virtual XXX Blind Switch is On, execute voice command "Open the XXX blinds")
