Wiring Diagram (Please check your controller model as it may differ from desk to desk):

Thank you for sharing this!
I found my standing desk´s documentation on interfacing with their controller.

Could you shed some light into how could I adapt your code to their hex commands? I gave it a shot, but not sure if I translated it correctly.

@sibero80 Do you have a link for that table?

If it's loctekmotion, then I think you need the 0x9b and 0x9d start and end bytes.

@sibero80 Do you have a link for that table?

It's loctekmotion, then I think you need the 0x9b and 0x9d start and end bytes.

It Dihool brand is a 4-ch controller I bought to Frankenstein my very large L-shaped desk, which needs 4 linear actuators.

Here's the full manual.

Do you think my translated code would work as-is? I can try it on my own. Is there any risk for controllers if I send a malformed packet?

Almost certainly won't work if it's not a loctekmotion controller.

But it looks like you just need an RS485 to Serial converter, as on page 11. And you don't need the esphome component, which does the interpretation of the 7-segment display codes to height reading.

Did you use the same wiring and yaml file for your E7 Pro? Mine is running controller CB38M2L-(IB)-4 and interface HS13A-1C0
