Hi folks.
I have MAIAMI Model S100102. Main Board version:

Display version:

I'd make D1-mini board by Raomin instructions, the web UI and MQTT works good.
hwtest passed without errors. Display shows IP and date on boot. All buttons presses sounds, Power button and F led lights permanently and digits display not lightning. Presses on any button do nothing, so via web UI.

My Hardware config in web UI:
CIO - 6 wire, 54149E (air)
DSP - 6 wire, pre 2021 (air)
PCB: Custom
Pinout: CIO - 4,3,2 - DSP 7,6,5,0
I tried all possible variations of the config, this is the best result I'd get. Others or nothing work or without sounds on buttons presses.
It's looks like the main board have different set of commands.

Any idea , what wrong?

So just to confirm, display works upon boot and then after booting it turns off?
Have you checked if display buttons are enabled in spa config

I'm not familar with LLC. Do you mean logic level converter? Like this ?
That means, the main board have to receive diffirent voltage? Which one, 3,3v or 5v ?

Insert the LLC between D1 an CIO? Ther is schematics anywhere?

Pass, I think that’s why most stick to the PCB board designed by VisualApproach
