Hi Folks - have you considered the automated curtains by Zemismart? (Zemismart Smart Curtain)
I have a 4 meter, 5 meter, and most recently a 2 meter track installed. The track has an innovative design to adjust to the right length and looks to be good build quality, easy to construct (although the instructions take a bit of deciphering) The motor sound is barely noticeable.
One drawback is that WiFi operation is through a Tuya dongle, however they also function from the included RF remote and RF wall switch. They can also be hardwired to a wall switch using an RJ-45 cable. To escape the Tuya dependency, I’ve mine wired to a WiFi wall switch, and integrated into HA using the switch and a template cover.
If you’re happy to go with Tuya, its a 2 hours install and done. I was (am) on a budget, and these just seemed about half the price of anything else. I’ve had them installed now for 2 - 8 months. The bedroom (4m) operates multiple times daily with heavy curtains and still runs like the day I installed it. Just wanted to share my $0.02. Take care, Dave.
