Please ignore it. I had issue with software serial implementation. I switch to different device with hardware uart and now it gives me 0xFF instead of 0x00.

I have telestart t91r and when i turned it on it always set time to 0x00 0x24 0x03 0x20 0x00 I can read that in byte 9 is stored 0x20 0x00 But when i use command WBUS_CMD_SL_WR 0x33 or WBUS_CMD_EEPROM_WR 0x36 I'm not able to set it up. It is always 0x20 0x00
