How to make control by bluetooth or infrared?
I have a heat exchanger (breather-type supply ventilation), which is controlled in two ways: with an IR remote control and via Bluetooth.
There is no scheduled turn-on function, but I really want to turn it on at 2 o'clock in the morning when I definitely fell asleep and so as not to interfere with falling asleep.
I have thoughts so far:
1. Buy some kind of universal programmable infrared port, it seems that even xiaomi had some kind of cube. And somehow count the signal of the power button on it and send it according to the schedule at 2 am.
2. Take some cheap Android, put a Bluetooth control program on it and somehow go in there so that it presses itself in this program. And leave your phone at home on charge forever.
What is the easiest way to implement this?

I’ll also give you options:
1. Use Arduino, there are bluetooth modules for it, and an IR diode can be screwed to it, so it fits both in the version with bluetooth and in the version with IR port.
2. Send a bluetooth signal, on schedule, from your home computer.
For my taste, the most accurate thing will be with Arduino.
PS If your device can work immediately after power is applied, then there are still sockets with a timer. Perhaps they will be the simplest solution.
Some smartphones have an infrared port on board.
You can use the event scheduler and write a script so that the smartphone turns on ventilation according to the schedule. True, the phone will have to be remembered to be directed to the right place.
It's fairly easy to implement on Arduino. Firstly, you need to assemble an IR receiver (Arduin + IR phototransistor) to read the signals of the existing remote control, and then control these signals, assemble an IR transmitter (Arduin + IR LED + RTC module).
