Zemismart Smart Curtain | Review & Install 

nice! how's the Xaiomi app?

I noticed that too. Fortunately MrZzs has not... yet. Thanks for the idea. When she finally complains about it I'll have a solution ready!

Thanks!

I concur. I wish we would just convert to metrics already. Too much American stubbornness. The British don't even use that system anymore and they invented it!

let me know what you come up with.

@@DrZzs Will do fella.

I forgot I made this comment :) - Here's a video of the first part, testing my idea ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-R08FdiPXUDI.html

ooh, that's a good idea. Different hooks would do nicely I think. Thanks!

Yes, there are tracks that are like 20cm etc, you should check the table on the sellers site with track lenghts

Not sure if you already resolved this but I had similar problem and did the following: Change curtain direction Direction Change When the motor run in different direction which is not same as the emitter order, user could operate as follows: Press the CLOSE & OPEN together The motor will vibrateonce in every direction long press STOP within 3 times quickly The motor will vibrateonce in every direction Direction Changeis finished

Having the rail up higher on the wall will cut the light more and reduce the heat leaking out the window too..

now that you say that it makes total sense. Wonder why they would include that weird remote to control them separately if there's only one motor? Thanks!

@@DrZzs I vote the control is if you have two windows in the room. Train button-set-A for the east windows, train button-set-B for the south windows. Control both from your arm chair

ya, that makes sense.

hmm, do you have other Tuya devices working in HA? If you aren't getting the entity_id (jumblebunch of numbers), then maybe the Tuya component isn't connecting correctly to the Tuya servers. Check your HA logs for anything that looks like a failure of the Tuya component. All the Tuya switches should work with the official Tuya HA component.

@@DrZzs nothing in the logs. It's a bare 0.95.4 install with no other components. I got a switch and a thermostat on the way. Is it better to use the Tuya app or the Smart Life app? Both seem to work and look identical.

@@DrZzs Ok, just received the thermostat for the electric underfloor heating and the dimmer switch. Both showing up in HA with no issues, so it must be the curtain switch which is the issue here. I guess I need to find a different one which actually works. Thanks again for your reply, really appreciated. Oh, and please keep these great videos coming, they really help to keep my sanity when it comes to all things HA!

glad you have some devices working. Bummer that one is messed up.

probably not this one. Possibly if/when they send me another.

(RU-vid ate my comment?) My Zemismart curtains arrived this week. So of course the motor house is in pieces and wired to the computer. The white metal box contains a motor with gearboxes and end-sensors (back-emf or position most likely). 12VDC. There are two blue circuit boards, one is a switch-mode PSU, 240VAC to 12VDC. The second board has a 433MHz radio module, op-amp for the position sensors, motor drivers, an RS485 driver(!) (Attached to the RJ12 on the bottom), and the brains is a PIC micro. The "USB" port on the bottom is not USB, but 9600 serial on the USB1.0 pins, and a blue led control on USB3 R+. The little white dongle contains a Tuya TYWE1S, esp8266 +2M flash. So, all the smarts for hacking are in the dongle. I just need to work out how it is talking to the PIC micro. It is 9600, but what does 0x55 AA 00 00 00 00 FF mean?

that's odd. I'm not sure. I think they have a rep on facebook that might be able to help. Search Zemismart on facebook.

DrZzs I figured it out! It was as simple as putting the tracks the "wrong way round". Difficult to explain here but I ran the tracks on the opposite sides to the manual (I had it coming out the top on the right side for e.g.). Switched them to match the manual and all is well.

doh! cursed manual was probably upside down!

Tried this: Change curtain direction Direction Change When the motor run in different direction which is not same as the emitter order, user could operate as follows: Press the CLOSE & OPEN together The motor will vibrateonce in every direction long press STOP within 3 times quickly The motor will vibrateonce in every direction Direction Changeis finished

oh shoot. sorry. well, I can tell you they are really quiet. much more quiet than the motors I've been using for blinds and shades and such lately. Let me see if I can find the original clip with the sound.

just for you brother! ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-RrrUem6esUk.html

Good question. Sorry I don't have the answer.

I did, and they don't. I had intended to show that in the video but it was getting long already. I was disappointed not to get a code in Tasmota when I activated the remotes. Maybe if you can capture the raw RF data, but that requires changing the firmware on the RF chip too and I haven't done that.

@@DrZzs Thanks DOC!, but if they have wifi, they are cool :)

That is the question. And I don't have the answer. Not until I have another one to play with. Maybe they'll send me another to hack into.

@@DrZzs So my Zemismart curtain motor arrived today and is in pieces around me. Model BCM300D-TY. WiFi, no Zigbee/Z-Wave. Held together with annoying triangle "security" screws. The main board has motor drivers (12V DC brushed), an RF433MHz daughterboard, an RS485 driver and the main chip is a PIC16F1829-1. The "USB" dongle has the Tuya radio modem. I don't think it is talking USB over the pins. Not going to plug this into a PC to find out! Since the main board only has a PIC, it's not worth the disassembly; for the one I own, the little "USB" dongle is where the hacking lives. Will need to break down the protocol from PIC to Tuya, so I can teach Tasmota how to talk it.

I'm hoping to get another device to try it on.

I would guess it's about 5 lbs

good idea! thanks

which kind are you talking about? I don't have any roller blinds, but I'd be willing to figure out a way for you to motorize yours. Let me know.

@@DrZzs looking for a cost effective option along the lines of those rechargeable somfy motors which are super expensive. There's cheap motors everywhere, but it's knowing which ones are gonna work with home automation with a battery. .

pluggin in the usb doesnt get the red light blinking for me

hmmmm not sure then. The instructions weren't very clear on that point. I just stumbled on the solution myself.

Ever figure this out?

my ol'pappy used to tell me "if someone offers you a motorized curtain controller with wifi that works with Home Assistant, you say Yes!" So I did. :)

Besides this way he can work through the problems and come up with a even better 2.0 on a budget

that's right!

check the free space on your drive. Sometimes the homeassistant.db gets super huge and it can take forever for the history to load. There's a "recorder" component you can set up to purge the db after X number of days and limit the info that gets recorded in the db. I did an example of it some time ago. I'm sorry I don't remember exactly where or in which video.

@@DrZzs thank you. I will check it out. 👍👍

Excellent!

@@DrZzs Thanks Doc. 👍

209 on Amazon he has a links in the description

can get better price on offical store, www.zemismart.com/zemismart-smart-curtain-alexa-google-home-electric-stage-curtain-motorized-tuya-wifi-curtain-motor-with-track-p0160.html

haha. I'm sure they were just trying to give a thumbs up so fast that they accidentally pressed the wrong one. Honest mistake :)
