Improvement: Still be able to use the control panels

[staxDB]

It would be awesome if you could still use the control panel. The ESP8266 would have to read the incoming signals from the control panel and pass them on to the control unit. The same applies the other way round: Everything that is read from the control unit should also be written back to the control panel. Would such a setup be possible?

RJ45 PIN	Original cable color	Ethernet cable color	Description	ESP8266 GPIO > Control Unit	ESP8266 GPIO > Control Panel	Control Panel
1	brown	white-orange	RES			RES
2	white	orange	SWIM			SWIM
3	purple	white-green	N/C			N/C
4	red	blue	Enable / Awake	D2	?	Enable / Awake
5	green	white-blue	RX (of remote)	D6	D1	TX (of remote)
6	black	green	TX (of remote)	D5	D0	RX (of remote)
7	blue	white-brown	GND			GND
8	yellow	brown	VDD (5V)			VDD (5V)

The ESP8266 itself could be supplied with power via e.g. USB, so that the control panel could use the power supply from the control unit.

Have you tried a simple RJ45 splitter? I wonder if that would work as well..

Otherwise; it would be interesting to investigate if you can pass through all communication indeed.

I will give it a try

Splitting don't work 100%. The ESP can only read the value of the height of the table. I disconnected GND and 5V and added a power via USB. Everything with the Controller works

Are you able to connect the control panel to the ESP and listen command?

P.S. I want connect HS11B-1 to ESP-32 Lolin32 and use it in my project (without table controler) to read command from control panel

Isn't that already possible? My desk seems to have two controller ports. Or is that only on specific models?

[iMicknl]

@dasfuu my desk also has two controller ports, but unfortunately there are some models with just one controller port. That's the same reason why I haven't spend any time on researching this.

@staxDB Do you have some progress on this?

@NazarLysyi My Flexispot E5 has only one Port, Controller Model CB38M2A-1

Anyone has success with this? Alternatively i guess an external keypad connected to other GPIO's can do the trick too (minus the display)

I haven't heard it yet, however feel free to join us on Discord to discuss further. I don't think that we have users there yet who only have a single input, however perhaps they have an idea :-).

@iMicknl you can close this issue with my pull request as well
