For those of you who are struggling with the integration and looking for a solution here is the solution or at least what I’ve done and it’s working perfectly, you can buy this or you can build it by yourselves using an ESP32 and adding a USB-A male, using this schematic
| Connection | USB A | ESP32 |
|---|---|---|
| - | Black | GND |
| TX | White | TX |
| RX | Green | RX |
| + | Red | VCC/5v |
Next step would be upload the ESPHOME code:
esphome:

Once you have everything setup you should be able to plug it to the HVAC Bosch i5000 or i3000 ,and then connect to your home assistant instance to control it via ESPhome integration.
Hope this solves for you
