Supports remote controls (e.g. RB4) for SP530e

[mik-laj]

Hello,

I bought the SP530E controller with the RB4 remote control. Next, I installed WLED to control my LEDs, but later I realized that WLED does not support RB4.

I wonder how I can use RB4 now. The documentation says it's something at 2.4 GHz, but doesn't go into details. Has anyone looked at what protocol is used there?

It would be ideal to add support for Home Assistant, but if that wasn't possible then at least writing a module for ESPHome that would allow the signal to be passed to HA would be equally useful.

I disassembled the device and took photos of the circuits inside, which may be useful to us.

I found a datasheet on Google. Here is a copy: https://drive.google.com/file/d/19xdyp2wp6p-PIa4VBV2ZbAqzqLEUBxqd/view?usp=drivesdk
This module is described as: ST17H66B2
Bluetooth Low Energy System on Chip with SIG-Mesh

On AliExpress we can find other remote controls, but I don't have access to them.

Thanks in advance for tips on how we can integrate this pilot with HA. I think there are more people in this project who have these devices, so I wrote here. I hope that together we will be able to develop something.
