Thanks for the reply. After browsing that list, it appears to be the JCB35NH2: Control Box JCB35NH2 - JIECANG
I’m only basing that off of the fact it has the same ports, looks to be the same size and is also 400w.

So there’s a decent chance it should work with this project. You just need to keep an eye out for the “secondary or alternative protocol” mentioned in this thread (which is not yet supported).

Just wanted to report back my findings. I got the desk working with Option #1 in the original post! I changed the units to inches and also changed my limits to match. Still tweaking with it slightly but it moves up and down and reports height in Home Assistant!
Thanks again for the help!

Thanks! I had one last question. I’m actually using the “Desk Is Moving” state to control a zigbee plug that energizes/de-energizes an electromagnet that is mounted to my desk that attaches to a steel plate I mounted to my wall. Well, the zigbee plug is too slow to turn on/off with the “Desk Is Moving” state.
Do you think I could use an output on the D1 Mini that fires when that “Desk Is Moving” state is true?
Edit: disregard, I figured out how to add the output. Had to just play with it some more 
I’m still fairly new to esphome in general. Super excited for this!

You’ve got me curious about this!
Would you mind sharing the use case?
Yeah definitely. So, I am a big proponent of having a rigid benchtop and desktop, so I typically just bolt my desks to the wall with a big L bracket. Well, you obviously can’t do that with a standing desk, so I bought a piece of 6" x 30" steel and mounted it to the wall behind my desk and bought an electromagnet from amazon that is meant to hold doors shut. I printed a mount to hold the magnet to the desk and it has like a 350lb rating.
I’m currently using a zigbee plug with a 12v power supply plugged into it to control the electromagnet. Ideally, I’d like to control this zigbee plug with the “desk is moving” bit in home assistant, however there is too much delay between when I press the down button, and the zigbee plug turns off. It’s only like a second or two, but that’s enough to bind up the desk and cause the magnet to keep holding.
This is where my question came in. I plan on controlling the magnet with an output from the D1 to a relay that allows the 12v to go to the magnet instead. I think this will give a much more instant response than waiting for the zigbee plug. The magnet takes like 1-2 seconds to energize, however it de-energizes very quickly, allowing the desk to move.
Here are some pictures to get a better idea, and this is the electromagnet that I am using (I took it out of its case since that just added bulk).
Ah I see. So it is an anti-wobble device?
Yep. Albeit, maybe a little over-engineered or overkill, but that’s kind of why we’re all here, right? haha

You might get a laugh out of one of my lockdown projects then. It was a bit of failure in the end but was fun to build.
Oh my goodness, this is amazing! Yeah, not going to mention “overkill” again, I now know I’m in the right place haha.

Hello @jcastro. Do you have the big fully controller with display or only the small one?
Could you maybe DM me your ESPHome config? I cant get the logging working.
Also my display isnt working anymore on the fully controller when my passthrough is connected. @Mahko_Mahko do you maybe have an idea about this?

HA Details
Up and down is working.
One last thing i noticed:
The desk usually is showing the height in inch not cm or mm when the display is working.
I also opend my controller board and checked my RJ45 layout. It matched the config from #Option 1
UPDATE:
I had to solder the TX pin of the controller to GPIO17 instead of GPIO3. No I’m getting the uart logs. I still facing the same issue as @jcastro. When looking at my logs the 5th and the 6th byte caltulate my desk height. Therefore i still cant see the height in HA. I managed to switch from inch to cm in the controllers settings.
@Mahko_Mahko @ssieb do you have any further tips how to get the height to work?

Interesting. So you’re the second person in addition to @jcastro who has a desk that uses a slightly different protocol.
The feature request for supporting that has been open for some time.
What I’d encourage you both to do is make a comment on the issue to help flag to @ssieb that there is still demand for the enhancement.
You could also take a look at the Upsy Desky project and try to figure out if your protocol is already supported.
If you are willing to tinker in cpp I suspect it would be relatively small adjustments to this code section to just read bytes in two different positions.
Thanks for your response. I will make a comment tomorrow. I also will check the c++ config. Maybe I can figure it out by myself. Not really into c++ but we’ll see.

ssieb is active on the development of support for this alternative protocol now (beta has been released), so if you still have some interest and the hardware, more testers would be helpful.

I can confirm @ssieb work. I tried his solution with my Fully Jarvis Desk.
Everything works like a charm. @jcastro you could also try it now. Should also work with your desk.
How to update the repository:
Clean the Build folder of your ESP32 and reinstall the yaml file. This way the repository should update. You also could change your config in the following way and reinstall:

@hraschan would you mind sharing your whole config? I don’t have mine anymore. I’m using ESP8266 so I will just change the pin numbers. Thanks
Please keep in mind that i also configured my 4 memory buttons. As i remember you got the small controller. Therefor you don’t need them. Also make sure your uart config is right. I also changed that. Because I needed a different pin there as well.
