How to duplicate the signal from the roller shutter remote control at 433 mhz?

Question

Do it yourself

Hello!
Tell me, is there any device for 433 Mhz radio similar to learning remotes?
In a rented apartment, Simu roller shutters with a simple up and down remote control, I want to control them from a smartphone, set a timer, etc. but such a stray costs 200+ euros (simu livein).
Is it possible to buy a cheap transmitter and duplicate the signal?
Noob in such matters :)
Thanks in advance for any tips where to dig.

Answer 1

You take ESP8266 connect with wires with 433Mhz .
You connect ESP to Wi-Fi and communicate with the phone via mqtt.
From the phone you send a signal 1 - open 0 - close, ESP receives the signal and says 433 generate a signal for the gate. gates receive a signal - joy.
EDIT
BUT, in order to know what signals the remote control sends for opening / closing, so that later they can be emitted by a 433 transmitter, see the lesson above, paragraph "Program for the receiver"
EDIT 2
By the way, there are libraries for 433, but for arduino, they are not suitable for ESP, only one is suitable
This is what I found out by experience.
