I've been looking for something like this. Is it DIY or something off-the-shelf? My spouse requires absolute darkness when sleeping, but I have SAD and require the blinds to be always open in order to... not want to die.
Not the OP but I am really happy with the IKEA Tradfri blinds [1].Every night at dark they close all the rooms so I don't feel like living in fish bowl. 30 minutes past sunrise they all open. Best investment ever.
For the more technical they are Zigbee and heard all of IKEA zigbee stuff works without the hub. I personally have had issues with HomeAssistant and Tradfri integration so just use the IKEA app and the hub with no issues for over 6mo now.
Directly connecting these blinds to my Home Assistant instance via the ZHA integration and a HUSBZB-1 Zigbee/ZWave stick[0] works pretty well. I've got 8 of them around my house, and some automations to open/close with the sun, etc.
Only small issues I've identified are that 1) Zigbee meshing doesn't seem to behave with these, so you'll have to pair the blinds directly to your hub. This is fine, as long as your place is small enough for there to be no signal quality issues. And 2) if Home Assistant instructs the blinds to open to a specific position (i.e. "80% closed") rather than fully open or fully closed, it can take a really long time for the blinds to update the hub with their state. This means they show as "opening" in the HA UI even though they're finished moving.
I use zemi smart curtains, they were a huge pain to assemble but work great now. We’re just using the remote so I can’t comment on the smart home features
