Automating roller blinds (aussie.zone)

I have 2 windows/doors in my living room which have 3 roller blinds each (6 in total) that I'm in the process of automating. I have purchased and installed 1 Zigbee motor that goes inside the tube that can lift 4kg using 0.8nm of torque, this is working well and I want to buy the rest. A couple of the blinds are longer and I am considering a 2nm version which can handle 10kg. If install a mix of these motors will they all move at the same rate or will they operate at different speeds?

When I press the button I want all of the blinds to raise/lower at the same speed.

Any advice appreciated.

Thanks for the feedback, I didnt realise this was unrealistic.

I think it is realistic but to achieve that you'd need to spend a ton of extra money for a out of the box commercial solution. I have the ikea shades as well and it doesn't really bother me too much if they raise at different rates. I set them to open to a specific percentage so they all wind up in the same spot anyways.

I agree, there are some blinds that use different protocols, use different motors etc that should be able to do this but probably at x2-x3 the cost or more.

If having them all raise/lower the same is unrealistic, maybe you could make a script that starts each one moving with a delay to create a staggered effect? It would still look visually pleasant IMO without the difficulty of syncing up different motors.
