Ever since I got in to Home Automation I fancied having some electric curtains and blinds but the main stream stuff like Somfy is expensive. I started a thread a while ago here on the Micasaverde Vera user forum talking about options for cheaper electric curtains and how to go about possibly Z-waving them up. Mainly looking at China specials on sites like Aliexpress.com. In the end I never got around to purchasing anything.
Recently I revisited the thread I had started again to find lots of new input from other users and it seems the general consensus for curtain rail tracks was to use the standard Dooya motors, which was one of the companies I originally discovered during my initial research. As it turns out Dooya is a high quality China brand and I believe Somfy have bought in to them as well!
The motor I am going to be using is the Dooya DT52S which is an AC motor, S being the important part of the model number as there is also a DT52E model. The S is a standard motor with no inbuilt RF controller.
There are 3 different versions of the DT52S motor 45W, 60W and 75W which can handle different weights of curtain material. You can also get Dooya DC motors but they tend to be more noisy in my experience of seeing the difference between the Somfy AC and DC motors.
DT52S Motor Versions:
Dooya Curtain Motors AC and DC:
The tracks are driven by a rubber belt rather than metal wires like in some of the other lower quality kits you can find online, which makes for quieter operation. You can get straight or bent / curved tracks.
Update from Seller: Regarding curved tracks – We can only make 135 degree and 90 degree curved track. The other degrees of curved track is very difficult to deliver. So we only send 135 and 90 degree curved ones to buyers abroad.
I ordered a 2.3 metre straight track and motor for my living room window, from a Chinese supplier on AliExpress which was recommended to me off that Micasaverde forum thread. The company is called Friend Group and I spoke to a guy called Scott. I was told on the forum that I wouldn’t see a product page for exactly what I wanted to order, but you have to contact them and request what you want and then they sent me a link to a product page to make a purchase. I still needed to enter in to the “message to seller” box at checkout, confirmation of my requirements which were:
- Dooya DT52S 45W Motor
- 225 CM Track end-to-end width
- Wall Mount Fixings
- Two-way Draw (Centre Opening)
I also sent them photos of my living room window area just to be on the safe side, so they could see what I was talking about.
UPDATE: Friend Group have created a whole new product page for the Dooya DT52S motor and curtains rails as a result of this series of blog posts, which should make ordering for you simpler.
NOTE: If you do place an order with Friend Group, please tell them you were referred to them by “The Media Center Blog”.
For this 2.3 Metre track and motor the cost was only £50.95 GBP. However postage was £33.27. I also had to pay some UK customs import VAT tax on top of that, which was £22.50 (think they over charged me) and an additional £13.50 for the Parcel Force International (UK) handling fee which I wasn’t expecting, so the grand total was £120.22 landed. However I still think it was fairly cheap considering when you look at other prices for other curtain track systems and I am confident these Dooya motors will be of good quality.
The Dooya motor can be fitted to either end of the track left or right is OK, I plan to have mine on the left hand side.
Friend Group will even customize the track to the exact length you require, so I bought a 2.3 Metre track but my actual width requirement is 225 CM. This saved me the hassle of having to take apart the track and get out my hack-saw, nice one!
You can also get ceiling fixings instead of wall mount fixings and you can have a One-Way Draw (Side opening) for say a single curtain rather than the traditional two curtain centre opening as I required.

This is the small window to be covered.
So now you need a Z-wave blind control relay module. There are many on the market and I expect most would work with this type of curtain motor. I am going to be using a Fibaro Blind Control Insert 2.
I am actually an authorised Z-wave Euro dealer, so if you want any Euro Z-wave kit at bespoke prices then just contact me with your requirements for a quotation.
Product number FIB_FGRM-222. Fibaro has traditionally been for EU Z-wave frequency but I believe you can now also get these inserts in US frequency as well.
I found a really nice blog post by a chap called Chris in Singapore here who has pictures and videos about this same setup, using the FGRM-222 insert and the Dooya DT52S Motor. His blog post was the final inspiration for me to push the button and go ahead and finally order some kit for myself! Hopefully my series of blog posts will do the same for you!
I plan to also use a wall mounted switch nearby the curtains for opening and closing them, the switch connects to the Fibaro blind control insert, something like these Scolmore Minigrid switches. I couldn’t really find any cheap switches specifically for curtain / blind control with the Up / Down arrow icons or with curtain icons on them.

MD075WH – Click White 10A 3 Position Retractive Switch Minigrid Module
I choose this particular 3 position retractive or momentary switch because I thought this type of switch would be good for use with Curtains and blinds, up for open and down for closed. The default position of the switch is in the middle (off). When you push the button up or down and release, the button automatically then returns to the middle position hence the name retractive.
With these Dooya motors the curtains can not be manually pulled to start an open or close operation, unlike some of the Somfy curtain track motors which allow you to do this. I would say this is the only feature I would like that I won’t have with this budget project, making a nearby wall switch even more important.
Obviously we will be able to use this wall switch along with the Vera mobile apps on the phones and tablets to open and close the curtains and maybe also use an Aeon Minimote handset as well, if I program one of those. We will also be able to automate the curtains to open and close at certain times of the day and night with scheduled scenes in Vera.

This is the planned wiring diagram, which I borrowed from Vesternet, which I interpret as:
- Earth / Ground from the 240V mains connects direct to the motor.
- Neutral from the 240V mains connects to both the N on the Fibaro module and to the motor.
- Live from the 240V mains connects to the L on Fibaro module and then to the wall switch (COM).
- S1 and S2 on the Fibaro module connects to the wall switch for manual up / down operation.
- O1 and O2 on the Fibaro module connects to the motor for Up / down operation.
These are the wires coming from the Dooya DT52S motor. Yellow is Earth / Ground, Blue is Neutral and the Black and Brown are for Up / Down, not sure which is which yet.
Disclaimer: You should always seek professional advice from a certified electrician regarding installation, as mains voltage can be very dangerous!
