@ vladimirzrnic Thanks for your efforts but the file seems to be deleted. I have send you a private message in hope to receive it via email.

try again now, I managed to download. (via google drive)
I have the ESP32 and LM2596S already here so thats no problems.
But what is the “TTL to RS485”? I cannot see where it is on the board.
Also what is the 6 pin socket on the board?
I sent off my order for the PCB today
This is a module that allows the TTL interface of the microcontroller to be transferred to the RS485 module.
TTL-RS485 should be installed under ESP32.
Regarding the pinout, see my previous post.

Can this be used with the Supramatic E3, is it just a matter of requiring the connector? Its much simpler than the other solution!
Perfect thanks so much, I thought something was hiding 
Great project. It would be great if there was a thread that gave some kind of step by step instructions.
I would also like to do this, but somehow I do not quite understand where to start , and what I actually need everything.
Maybe there is a way to do that?
I would definitely be very grateful
@fisch55 you need Hormann Supramatic 4 or Promatic 4 (4 series is needed). I mean - @Dr.Pat 's code is for that. I onlt have experience with this model. Do you have any of that?
Currently running this via raspberrymatic Ip .but would love to switch to the mqtt story. Got the Supramatic4 !
@fisch55 you need 3 HW pieces. This is what I used:
ESP32:

Stepdown module for converting 25V (from hormann) to 5V (for ESP)

And I used this RS485 module as it has built in 120Ohm resistor (you need to solder 2 pins together to use it)
https://www.aliexpress.com/item/1005001580305871.html?spm=a2g0o.order_detail.order_detail_item.3.5dc8f19cApsIph
Rest is just soldering those pieces together according to schematics and upload Dr.Pat’s code with adjusted MQTT details.
I am using for some statuses also device that gets autodiscovered, but due to (I believe) limitation about state/position reporting, when I open gate, and stop it before it opens fully, then this device does not let me close it, arrow down is greyed out. So I templated MQTT cover that does not have this “limitation” as it works based on position value (0-100), but this does not have state (opening, closing, unknown) and I can’t template it as target position is not being published in MQTT (only on web, for which you would need to poll regularly).
So for opening/closing status, I use autodiscovered device. But for operating the gate, I use templated MQTT cover (see above posts).
I am using device that

Cool , THX a lot for these informations!!!
And this….right?! The only part I can’t find ist the socket !
Actually I Got this
which rj12 socket should I use?
So - you already have HAP 1 module. This project here emulates it without need to actually have it.
Regarding the soldering and socket - it is really up to you how you put it together. I don’t have the board for instance, I directly lead those 6 wires from RJ12 to where it needs to go.

ok thx!
What is the difference between Dr.Pats code and @tsaG1337 esphome variant?
@tsaG1337 do not use the mqtt , right?
The PCB design was done with Molex C240856 but I am sure you can find a compatible one in your local shop. When I started to assemble the whole thing, I couldn’t find a Molex socket, so I bought a replacement. When the PCBs arrive, you can try to make sure it fits. Please note you can use a straight or angled socket

ok thx, i ordered everything I need…
and for the esp I should use this , right? Sorry for all the questions… It’s the first time do handle with esp…
I am using code by @Dr.Pat but I am experiencing strange behavior. Whenever I restart ESP in webui, or power-cycle the Hormann gate, gate is triggered (so it opens if closed, or closes if opened). Anyone would have an idea?
Ok , that’s a little bad.
After Power failure , garage door open ?!
That is what happens to me. I have Supramatic P4
This is not good. Does anyone have any idea what this could be? I mean that is an important thing that this does not happen.
