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.
