So there are quite a few topics on people not suceeding to find a cheap device for making your doors close and open automatically. Actually no matter which motor is quite expensive.
There are swing window openers on Aliexpress that cost around 70€ shipped to EU. However any kind of door opener is very expensive.
The clearly cheapest option seems to be the Deper DSW-100N. I bought it for 165€ shipped from Germany - but today it is even on sale for 143€ minus 20€ voucher on Aliexpress with shipping from China to Germany.
This motor is sold under various labels/names - a good description is on here:
I did not know when I ordered if I get the new model DSW-100N or the old model DSW-100 - but I got the new model for 165€ euroes. (Today it’s 155€ - some days lowest price was 202€ from Europe - shipped from China I’ve seen it starting 125€ including shipping but without any accessories as included here - here you get 2 buttons (no wires), one infrared sensor (no wires), two remote controls (they work out of the box), one smart lock panel with 5 RFID cards - again without cables or instruction how to wire it up) and both the pull and push arm plus an extender which I needed but I think is always included: https://www.aliexpress.com/item/1005008875907390.html?spm=a2g0o.order_list.order_list_main.5.7d5d1802DyAPZ9
Now it works really well - opens my door as indicated in 3-7 seconds depending on the setting, and manual opening/closing still works with a little bit more power too - BUT it’s not yet in home assistant. However there are loads of ports so I guess it must be quite easy to add some tuya device, or shelly? to make this thing smart. So I will attach in another post the instructions regarding the electronics and hope someone can help me out what to do. There is also a 24v backup battery option and that is supposed to be configurable if in case of no power the door stays open or closed - so I guess at worst cutting power and supplying instead 24v could be used for automations.
I will upload the pictures of the electrical wiring in my next post.
This is the same motor just crazy expensive but it already has Tuya:
So not sure what kind of device I need to add this to the OEM version but it’s clear it has to be possible quite easily.
I wonder if there is 12v supply on the pins already, or if I need to add a 12v power supply to the switch? I have no electrical testing kit but I do have a 12v pass through tuya device for door bells already at home that I could try if I know how to wire…
Okay, I found out. I need to connect a zigbee/wifi dry swith relay to J5.
If I then connect COM and 4 Hold open - it will be open. As soon as I drop the connection it will close.
If I connect COM with Lock - then the door cannot be pushed open - except by ripping out the screws, that would be the worst against burglars as with sufficient force the screws clearly don’t hold up in my case as the wall is just drywall were I screw it in. I still don’t know what action happens on oneway.
Kinda annoying there is no curtain swittch type of action - so cannot set it to any place between open and closed.
I tried shorting J1
Com with safey sensor open / safey sensor close and nothing happened. I may have fried it by stupidly connecting safey sensor open/close with the +12v misunderstanding a bit how it works.
The problem is that even the chinese instructions aren’t clear at all. I asked a friend who is Chinese native and it didn’t really help us out (I can speak fluently but not read and my chinese on electrical stuff is really bad)
Okay - well I still don’t know how to change the state of the relay upon manual door use.
I don’t know if there is any of the connectors that could throw the switch on a shelly/tuya dry relay device.
I tried J3 access control. But it does not work. I guess if I don’t find out the only solution would be another third party sensor that monitors the state of the door.
Actually you can put it manually into any position - the way to do so is to have it open - then close by hand until where you like it. Best set the keep open time to as short as possible - otherwise automations may not really work anymore.
So manually opening a little bit - will open and then quickly close. Opening via button/home assistant will keep it open. Closing will work except if you close via button while it’s still in the keepin open time. That will cause a bit of randomness.
Oh yeah - it’s really quiet vs cheaper motors. Not much of a motor sound at all. It uses like 50w for 0.5 seconds to initiate the opening/closing - then it uses very little power to finish the opening/closing. And on closing it doesn’t use enough power to fully set it back on my balcony door. It does have enough power to get out of that position - so it’s too bad this cannot be set higher to close strongly at the end.
So someone from deper replied me that it’s not possible. I’m not sure if that’s really the case or if he simply doesn’t know any better.
So I guess the only solution would be some additional sensor to monitor the door position or adding an sensor to the motor supply electric cable.
What I know by now is that the +12v and +24v supply DC power. So they are not for connecting an external power supply but can supply power to other devices. There is an ac-DC converter power supply somewhere in the dsw-100n.
What I still haven’t found a solution for is also how I could increase the closing power for the last slow motion part.
There is another big problem with the Deper DSW-100N - it loses the configuration on power loss. So even if you only lose power for a very short amount of time - you have to relearn the open and close position. Due to this any automation will be broken until the device has learnt it again.
Maybe that’s why there is the battery terminals… Sems it does not have any storage for setup values. Pretty annoying this is the only not crazily overpriced device for opening doors that is both fast and still allows operation by hand as it has the motor override.
