[BL602]Could this smart wifi switch work as a 2.4G RF gateway? (SONOFF/WOOLLEY SWITCH-WF)

My English is not very good. The following content was obtained through online translation services. If there are any errors, I am very sorry.

I bought a Smart DIY Switch that perfectly meets all my needs. But the biggest problem is that it heavily relies on cloud services (eWeLink) to work, so I want to use OpenBeken to achieve pure local control.

The Switch Information:
Brand Name: WOOLLEY
Model Number: SWITCH-WF
Purchase link: alibaba amazon.co.uk
WiFi: IEEE 802.11b/g/n 2.4 GHz
Note1: Only 2.4 GHz Support, Only eWelink APP Support
Note2: This brand seems to belong to the same company as brand Sonoff (sold by the same company)

One of the functions I need the most is that the switch can be controlled by the remote control, which is called "2.4 G Wireless Stick-on Smart Wall Switch" by the seller. This remote control is using 2.4G RF to control (from the manual, I cannot confirm if it is correct). To use a new remote control, we must complete remote pairing and button learning in eWeLink APP.

The remote control Information:

If I use OpenBeken, can I still achieve this remote control function, or even more powerful? For example:

In the original firmware, it is required that remote pairing and button learning, and I can only control one paired switch, can only control the switch on and off.

In OpenBeken, is it possible to achieve that the switch is used as a 2.4G RF gateway, accepting all remote control signals and sending them to HomeAssistant, who will complete the processing of operational logic.

(If this can be achieved, we can use this remote control to control other devices, not just this switch. For example, after pressing a button, switch A receives a 2.4G RF remote control signal, forwards it to HomeAssistant, and then controls device B to act (device B does not directly receive any 2.4G RF remote control signal)

I don't understand the specific implementation techniques, so the above ideas may seem a bit ridiculous.

Looking forward to the guidance from all experts, thank you very much!

This is a very interesting problem. I can't see any RF receiver on the board of the smart switch you've shown. Are you really sure it works with shown wall switch?

They might be using WiFi module RF somehow?

After several days of research, I have found that this remote control uses BLE instead of 2.4G RF. Because I can scan and receive BLE broadcast messages when I press the button,

So my request for help became "Could this smart Wi-Fi switch work as a BLE gateway?"

Thank you for your attention!

Okay, this makes a bit more sense, since BL602 indeed has BT capability. Now, do you know the details of BLE protocol used? BL602 SDK is open source and available on Github, but I haven't used myself BLE portion of BL602 yet.

no, I have no clue. (┬＿┬)

Well, so long story short, it should be theoretically possible to support the feature you mention, but:
1. I have never saw such a device before
2. You are the first one to mention that here on forum (thanks for bringing this to my attention, by the way)
3. It would require some research, especially considering that we can only change the firmware on BL602 side, so we would need to know the remote protocol

Are the devices with that kind of BT remote popular now?

Maybe not very popular.
More devices are remotely controlled through 433Mhz RF instead of Bluetooth. It's even difficult to find this remote control on shopping websites outside of China.

Perhaps spending a lot of time researching this is not very valuable. I should try other ways to implement the remote control function.

Do you need your wall switch/remote to be battery powered?

If not, you may use OBK with Tasmota Device Groups:
