Looking at that (particularly the number of wires), I’m pretty confident that this is not a Jiecang controller or a compatible desk.
The Desky component will not work. If you cannot find another matching project you will need to start your own project (and own thread).
You’ll see another would-be user had to do this here and has made great progress.
thanks for the info.
the main issue is that I can not find the reseller. maybe its easier or me to buy another desk controller, I’m not sure.
Definitely I will open a separate thread.
Apparently this is this desk controller: NT33-2B2 Sit to Stand Up Office Desk Motorized Standing Desk - Buy Sitting Desk, height adjustable desk, high adjustable desk Product on SHAOXING NAITE DRIVE TECHNOLOGY CO.,LTD
I’m guessing… But there has been a proliferation of cheap Chinese desks (not sure if this is one?). I suspect many work very similarly.
So I would hunt around other projects and see if you can spot a similar one. Then use or adapt it.
Yes. You basically just use/adapt/add this to trigger the memory presets, which use the soft start/stop.
thanks, so that I understand this. What do I add to trigger the memory presets?
Here’s the relevant excerpt from my config. Note the Purple wire needs to connected to a GPIO.

```ok thanks!
So, at the moment, I have it wired as suggested above
I’ll have to add an extra wire from the purple pin (or slot 3 on the above figure) of the adapter and place it on any of the empty pins on the D1 Mini?
That’s right.
Pick a pin that has “ok” in both the Input and Output columns here.
Awesome! Just did the addition and works very well.
I can now access my button presets and its a soft stop.
This project just keeps getting better and better. thanks again, all.
EDIT: @Mahko_Mahko one thing I’ve noticed is when the D1 board restarts, it goes to one of my presets (i.e. preset #2 in my case). My only concern with this is that on every update or even when the board restarts for whatever reason, it will go to a preset on its own. Is this an intended operation?
Here’s my entire yaml if there is something that is not right.

#Notes:
# 1. Use this component at own risk. It has not had extensive testing. May void warranty or cause desk faults etc.
# 2. This controller may bypass desk safety features like collision detection.
# 3. This component doesn't know about the values stored in your desk. Values in this config are (and must be) set independently.
# 4. ssieb's solution may be a lot simpler and cleaner for most people. I've cobbled together some more features in this config because I can't programn in C++.
#Troubleshooting Tips:
#If you ever get a flashing ASr message, you might need to reset your desk.

If this is the case, how do I make it such that its like Button 1, 3 and 4 and only command on button press. Thanks
Hmm yeah that’s no good.
Sounds like something is pulling the pin low on boot I think.
Maybe try another pin or two (rather than GPIO12) as a next step.
ok thanks for that.
I tried GPIO13, and it did the same thing (when board restarts, it goes to preset 2).
I don’t really have any other options as the other D1 and D2 are already used. May I ask why preset 2 is different in terms of yaml configuration? can the code be change to on_press instead?
EDIT: actually, the on_press may not solve the issue. I actually completely hashed out button 2 (using #) and after restart, it still went to preset 2.
The config for that button can be simpler/more direct for that wire as it only uses one wire.
But it shouldn’t be triggered on boot. Mine doesn’t.
I don’t know what’s triggering it and am somewhat out of ideas.
Maybe try activating pullup or pulldown resistors for the pin?
And separately maybe try commenting out the existing on_boot code and see if that changes anything.
And triple check your wiring for that pin.
Also, I recall seeing similar issues on this forum “thing X turns on/off momentarily on restart/ boot”. So maybe dig around to see if you can find a similar issue/solution.
Definitely look at early_pin_init
why you, sir, are a genius @Mahko_Mahko.
I read through all your suggestions but the last one made more sense so I started that first. I set early_pin_init: false and after the board updated and came back online…no desk movement, and even when I rebooted the board manually, no desk movement! problem is solved! thank you
hi, I have a desk from a manufacturer where the motor control box has two RJ-45 ports. My question is - can I plug the DIY remote controller in the second RJ-45 slot or do I have to create a passthrough box - so that the original physical controller and the DIY one are on the same connection?
Is it a Jiecang based desk?
hello, it says manufacturer: Loctek ergonomic technology corp.
Then you are probably better off over here.
Where I can see you’ve asked the same question…
Yeah, however, did not hey any response there yet and since then I realized that I actually have the motor from the same vendor. Anyway, my question was a bit generic - if having two rj45 ports pass through is the only way.
Thanks, anyway.
So I got this working a while ago and it’s been amazing. I’m trying to integrate it with some other stuff, and now I’d like to trigger automations based on the direction the desk is moving.
Is there a way to tell? The only way I can think of doing that is comparing the current height a second ago, but I have no clue how to do that.
