Bluetooth control of a LINAK device - can you clone the remote control?

Question

Hello,
I have a remote control like the one attached. Do you think it can be copied somehow to control the device by voice? While the remote from the TV is not a problem Tuya WiFi IR RF 433 RF 315, I wonder if it is possible to copy such a device?
Supposedly it's Bluetooth based, can the Bluetooth be copied somehow?
Any ideas?

Greetings,

Linak has representation in Warsaw and they are quite good to talk to. Call 22 295 09 70 and have a chat.

. In the Chrome or Edge browser, type chrome://bluetooth-internals/#devices or edge://bluetooth-internals/#devices in the address bar respectively and select Start Scan. See if it finds the controlled object. Maybe there is a sticker with a MAC address on it ?

There is a MAC address on the sticker. This may relate to WiFi, LAN or BT. Do an experiment with scanning in your browser. See if it finds the device 2C:74:89:A7:C5:CD. If there is such a device then try to connect to it (select Inspect).

I spoke to the Linak company, they are indeed OK, but they will not help.

Generally a tough subject, would need a particular electronics guy, gee, whiz with a soldering iron, de-composer ;-)

from the Zabrze area to take on the challenge.

What I really need is to hook up preferably two remotes (or rather two controls, one being the original remote and the other a voice control). I'm quite poor in health and, in order to reach for the remote at night and, for example, lift my legs so they stop hurting, I have to spend about 15 minutes doing this, which practically wakes me up.
I already have the infrastructure in place with Home Assistant and I can control some devices by voice, which has made my life much easier. For example, I have an actuator for a window and I can use the ESP32 to open and close it.
I've even wondered if it might be possible to solder such an ESP32 into such a control panel and feed a signal to the relays. It is possible that there is an Atmega or other microcontroller in there and maybe it would be possible to feed signals to the control from another microcontroller, but I am too small in the ears for such miracles...

After a power failure in the flat something, the control panel does not connect to my remote control, nor can it be seen at the link indicated. I checked on my phone, does it necessarily have to be a laptop with Wi-Fi?

The browser-based search function for BLE devices should also work on mobile devices. Activation may require additional user permission to enable the necessary permissions.
You can also try searching for BT devices using the system bookmarklet. You will also find BT2.0 devices via this route as long as they are in broadcast mode.
