I think using ESPlink with esp-01 connected to the Daly UART and using Antonius awesome flow will be work.
I made Esplink with Riden RD 6018 power supply and works pretty well. Should be work in this case.
CRC is sum of all bytes and Modulo 256 - CRC8 %256
also sum of all bytes &FF generate same value eq:
a5 40 90 08 00 00 00 00 00 00 00 00 and checksum 7d
a5+40+90+8= 17D
both sum%256(0x100)
sum&255(0xFF)
gives same result - 7D
