Plafond LED Ø 42 cm, 2400 lm, 22 W

I bought 2 of these. They can be controlled with the Tuya/Smartlife app. They give good light.
There are a few things that are not as they should be.
1. If you turn off the light with a switch on the wall (cuts off the power to the lamp) and then turn it back on, it does not remember the dimming level or color temperature from the last time the light was on. When the light is turned on with a switch on the wall, the light comes on with full strength and a warm color temperature.
Then you have to adjust the brightness down to the desired level with the app or the IR remote control.
2. and then we come to the second thing that does not work ideally. The IR remote control is very slow and not very responsive. You have to point at the lamp and hold the button for a long time for something to happen. If you press several buttons in a row, nothing happens.
The main reason I ended up here is that I want to see if it is possible to change the firmware so that it remembers the dim level from the last time the light was on or possibly set the dim level to 10% as standard when the power comes back on.
I have opened the lamp and taken some pictures.
The chip is CB3S and is mounted on a circuit board that can be easily removed. There is also an IR receiver on the small circuit board.
From what I can see on the circuit board (I have not measured, only seen where the print paths go)
The following pins are connected out from MCU to the large circuit board:
3.3 V
GND
P6
P7
In addition, P9 is connected to one of the legs on the IR receiver. The other 2 legs on the IR receiver are connected to 3.3 V and GND.
I have Homey Pro as the hub for my smart home. If possible I would like to be able to still integrate the lamp into Homey Pro, but the most important thing is that the lamp remembers the dim level from the last time it was on and that the IR control works more responsively. The app is basically not that important.
A possible alternative is to replace the MCU with ESP8266 or ESP32-C6, but then I need to know a little more details about the original code so that I can write my own code to control the lamp. And the easiest thing would probably be to make my own custom circuit board.
I appreciate input and guidance to make this lamp better.
