2 years ago I'm wondering whether it is usefull to read back actual selected channel by connecting LEDs from the remote to the ESP. Some remotes provide LEDs instead of an LCD.
I had the same idea, but unfortunately I was only using the remote with the LCD display so I never really explored this further.
How synchronisation is ensured without readback?
There's no synchronisation at all. That's the biggest issue with this project. I thought of various ways to solve this problem but never really implemented any of them because I switched to a different strategy entirely. Because I'm dealing with a large number of shutters spread across quite a bit of distance, controlling them centrally never worked as reliably as I needed it to. Instead of setting up multiple remotes in different places, I instead opted to modify the control board of each shutter so that I don't have to deal with RF at all.
Is there a special need for an ESP32? Isn't it overkill? A NodeMCU based on ESP8266 shoud do as well from a performance perspective, right?
Yeah, definitely. I just used what I had on hand at the time.
