Add support for Flexispot ED5

[amroncz]

Hello,

I am currently trying to make my Flexispot ED5 smart with the help of an ESP8266 and this repo.

The ED5 comes with the following control box:

And the following keypad:

I tried to adapt the wiring from this https://github.com/iMicknl/LoctekMotion_IoT/tree/main/packages/esphome#hs01b-1-with-esp32-as-passthrough-and-keypad-support
as follows:

I adapted the yaml file from https://github.com/iMicknl/LoctekMotion_IoT/blob/main/packages/esphome/flexispot_e5b_esp32.yaml and https://github.com/iMicknl/LoctekMotion_IoT/blob/main/packages/esphome/flexispot_e5b.yaml and it looks like this:

I have two questions about the yaml file:

1: Why do I have to configure the TX pin for the keypad if it says here (https://github.com/iMicknl/LoctekMotion_IoT/tree/main/packages/esphome#hs01b-1-with-esp32-as-passthrough-and-keypad-support): "esp32: no pin, keypad: RX, bridged to RX from controller"? So I used the unused D6 as a dummy... This is probably completely stupid.

2: My ESP8266 has only one TX and one RX (I think it's normal?), so I use D5 as a second RX pin for keypad. Is this correct?

I was able to successfully flash my ESP8266 via ESPHome with my configuration, but nothing works and I probably fried my ESP8266. I suspect that the wiring is not correct. Here is a more detailed overview of the wiring:

maybe this can help? Get out the oscilloscope

You should find the model of the keypad somewhere on the PCB. Otherwise you can trace the wires using a continuity tester and follow the "passthrough" instructions in the v1 archive: https://github.com/iMicknl/LoctekMotion_IoT/tree/main/archive/esphome.

Your ESP8266 also needs power. You can use the 5V from the desk if you connect it to the 5V input on your ESP8266 dev board.

You also need to bridge all of the other connections between the desk and the keypad.

I have also subscribed to the channel, but haven't seen the video yet. I will definitely watch it. Thank you.

You should find the model of the keypad somewhere on the PCB.

It's a little hard to see because there's this circular spring thing above the writing. It's something like "HS13U-...".

Otherwise you can trace the wires using a continuity tester

How does that work?

and follow the "passthrough" instructions in the v1 archive: https://github.com/iMicknl/LoctekMotion_IoT/tree/main/archive/esphome.

On the page I can only find the wiring for Loctek Motion (HS13A-1) Loctek Motion (HS01B-1). This will probably be completely different for me?

@amroncz Did you get this working in the end? I have a different control panel but the same control box as you. I've worked out the pinout and managed to capture all the codes for the buttons. Interestingly I get a different pin out for the RJ45 to the one in your wiring diagram:

8 -> 5v
7 -> GND
6 -> RX
5 -> TX
4 -> Pin20

I was hoping to just define a second UART and echo the traffic across them but the current code fails to compile with a second UART. Going to spend this weekend looking at either modifying the existing custom component to allow 2 UARTs or implementing the v1 code. I thought I'd find out if you managed to get it working?

Unfortunately, I still haven't managed to do it. After I fried 3 of my ESPs and got no help here or in the Discord, I put the project on hold for the time being.
I'll probably have to move on to simpler projects of this kind first, as I'm a complete noob.
If you find out anything, please let me know anyway.

With the help of Yama from the Discord, I've made a lot of progress.

I have the following problem:
If I connect ESP D5 and controller 6, everything but keypad inputs work.
If I connect controller 6 and keypad 6, everything but home assistant inputs work.
But if I connect all 3, nothing works. So how can I get the best of both worlds?
It looks as if the keypad cannot send any data. Nothing is logged when a button is pressed. So maybe keypad 6 is wired incorrectly?
