Remote control display

[revk]

I have started on a new project which is a remote control for the Faikin module, with a display and button.

What is it?

The board is mainly intended to accompany the Faikin controller boards providing a display and control button to control the aircon.

It has the advantage that it links over Bluetooth BLE so does not need MQTT or Home Assistant even. Wifi used for set up and additional settings.

The board also provides an environmental monitor, which you can use without the display module. The board can also be provided (soon) without the expensive SCD41 CO₂ sensor, but the initial boards have this fitted, sorry, it will be an option in due course.

My pre-installed code works with the Faikin board, but you can load ESPhome code, or other, and I also have general display signage code with Home Assistant reporting of sensors than can be flashed. My code allows it to work in various orientations as needed.

Why did you make it?

The Faikin work well, but there are people that want a simple control with a simple button, especially in our guest room.

What makes it special?
