WhatsMiner M64 - Board #3 (SM3) not detected

[andrey2676]

Hi,
I have a WhatsMiner M64 with 4 hash boards (SM0, SM1, SM2, SM3) but hass-miner only detects 3 boards (Board #0, #1, #2). Board #3 is missing.
Miner details:

Model: WhatsMiner M64
Firmware: standard
Cooling: Liquid cooling
Total boards: 4

Expected behavior:
All 4 boards should be detected:

Board #0 (SM0): ~28.7 TH/s
Board #1 (SM1): ~28.6 TH/s
Board #2 (SM2): ~30.2 TH/s
Board #3 (SM3): ~30.4 TH/s
Total: ~118 TH/s

Actual behavior:
Only 3 boards detected, total hashrate shows ~87 TH/s instead of ~118 TH/s.
hass-miner version: 1.2.6
Thank you!
