- From the modem port connect an ESPHOME (e.g ESP32 S3) and insert values into Home Assistant
- It's 868.35MHz radio between inner unit and outer unit, and make decoding of this device in rtl_433

Extrated with help of a raspberry pi and i2c-tools, Memory exist at adresss 0X50 as can be seen from below.
Note! I think one need to desolder the memory chips as there was different results.
i2cdetect -y 1

Seems to be 17 first bytes that contain some data
i2cdump -y 1 0x50

To read out the flash content from the CPU using reader like USBDM will get you and srecord clean1.s19 file. This file one need to convert to binary file clean1.bin with e.g objcopy.
objcopy --input-target=srec --output-target=binary clean1.s19 clean1.bin
