Hi there. First of, I´m german, so please excuse if my english isn´t perfect.
All the shutters in my house are controlled by electric shutter winders (don´t know the word in english). You simply push the up or down button and the shutter opens and closes.
Most of the Winders are from Schellenberg, model Rollodrive 45, but two of them are the Jarolift Eco Up 23/5. The Schellenberg PCB is allready documented, but the Jarolift is not.
The PCB is split in Mainboard which is built in the Case and the button PCB that is in the front. (Pic 1)
There are two exposed pins for power, this is where the relais board gets it´s power (Pic 2).
Pic 3 shows the already soldered wires that go to the relais, there are 3 exposed pins to solder to.
The Relais board I used is this:
This board works flawlessly with ESPHome and here is the yaml code:

“wintergarten” is the name of the relais board which controls the shutter.
I deleted the keys from Home Assistant API and ota for showing you the code.
The impuls script controls the buttons on the pcb. “AUF” means shutters up, “AB” means shutters down. The relais is triggered for 250ms which emulates a short button press.
And also there are some premade buttons for Home Assistant.
I 3D printed a small case for the relais board, which can be found here:
For my house the case fits behind the shutter motor.
I reinstalled the motor, set the endstops and then went into HA to find the Board allready found and waiting.
I created some small Buttons on the Dashboard with Bubblecard:
Works like a charm, and now I can set the times for the shutters to go up and down through HA without pressing the physical buttons.
I hope someone finds this useful, if there are any questions, please feel free.
Cheers, Michael
