FLEXISPOT EC5 - HS11A-1C0 + CB38M2H(PB)-1 compatibility ?

[M3te0r]

Hi,
Do you know if the HS11A-1C0 + CB38M2H(PB)-1 combo is compatible? It has one RJ45 cable going from the control block to the control panel



Thanks!

Update : Tested out the HS13B-1 pins conf since they seemed to correspond with the control panel wiring, took a LOLIN S3 Mini and a RJ45 connector, and it worked !

I had to adapt some parts of the config to match pins, min/max height and the 3rd preset

Here is my yaml

Question is :
I still want to use the keypad and there is only one RJ45 connector on the control block, the ESP32 can be powered on from the +5V, so could I just wire the ESP32 on the keypad PCB, right ?

What are the options if I want to keep the keypad ?

Update 2
Decided to buy 2 RJ45 female terminal connectors to handle the whole thing, looked at the esp32 keypad passthrough, a lot a yaml config files to handle position, cover stop, wake up command for move stop etc

• Wemos Lolin ESP32 S3 Mini, powered from USB
• +5V control block RJ45 <-> +5V keypad RJ45
• GND control block RJ45 <-> GND keypad RJ45

ESP32	Loctek Controller (E5)	Loctek Motion Cable Color (HS01B-1)
GND	GND	Blue
GPIO44	RX	Green
GPIO43	TX	Black
GPIO36	PIN 20	Red

ESP32	Loctek keypad (HS01B-1)	Loctek Motion Cable Color (HS01B-1)
	GND	Blue (Bridged to GND from controller)
	RX	Green (Bridged to RX from controller)
GPIO35	TX	Black
GPIO18	PIN 20	Red

It works great, i get to automate my desk and keep the keypad

I was getting some errors E07, E08 or Rst on the keypad, had to hold the down button till the desk reach the lowest height, but for now seems ok

Sometimes the esp switches or keypad buttons seem to not respond, looks like the esp32 restart itself, don't know why, even with reset_reason didn't get to understand why

I'm glad to see I'm not the only one triying to work with this specific interface.

I'm triying to make a "men in the middle" with an arduino mega, just to know how everything is moving (also, this is my first electronics experiment)

Hey @M3te0r,

I have the same controller, but my desks stops when sending one down or up command (0x9b, 0x06, 0x02, 0x02, 0x00, 0x0c, 0xa0, 0x9d). When moving the desk it stops between movements, making the move unsteady. Do you also have the same issue?

Im using an ESP8266 ESP-12F NodeMcu board.

Hi @Paulomart
The up/down commands have the same behaviour as the physical up/down button, a single slighty hold push will wake up the terminal and send a single up/down command, a longer push hold will continuously send the commands until you release the button

To simulate that hold behaviour you have to loop through a cycle of wake up, up/down, that's the intent behind the cover template, take a look at the open_action you might have to fine tune the delay, don't go too short or it will spam the terminal and you'll need to reset the controller

@M3te0r thanks I got it to work that way.

An issue I was facing: the sensor for the height was firing to often. I debounced the sensor and that seemed to help with smoother movement.

Here is my final setup:

Thanks for the extensive documentation @M3te0r!!!
I have the same PSU with my E.For.U® DT30 aka Ergofino DT30. (NOT PRO)

and i have another Button PCB but it seems to be similiar.
Color coding seems to be right/identical and since I have the same PSU i think it is similiar/same like your buttons.

PSU:

Buttons (not disassembled)

will test it in some time and report.

I got my E5 and it came with HS36B-1 and CB38M2H(PB)-2, which seem identical to yours, @M3te0r.

Got it working with @Paulomart's config + MQTT on an ESP8266 NodeMCU and am trying to implement the keypad passthrough.
Had a hard time understanding your wiring table :D
But I guess every wire not listed can be bridged.

Whats the reason you didn't use the 5+v to power the ESP?
