Need recommendation: Blackout roller blinds

Been using home assistant for about a year and absolutely love it.

In need of a blackout roller blind for a single 35 inch by 70 inch window in our movie room.

In searching the forums I’ve found several random recommendations but nothing specific for my application. Just visited our local Ikea and unfortunately their tradfri blinds are unavailable at my location in the US.

Does anyone have specific recommendations on what blinds, and or automating mechanism along with some lines I could use?

I’m currently not using sonoff or deconz or anything other than Z-Wave/zigbee via SmartThings.

Thanks in advance for any and all the help as I’m excited to replace the cardboard I currently have taped to the windows…!
