Compatibility and Configuration of APC BX850M-LM60 / BX1000M-LM60 with NUT

[sharklatan]

Hello,

I am trying to configure my APC UPS (model: BX850M-LM60 / BX1000M-LM60) with Network UPS Tools (NUT) for Home Assistant. While reviewing the list of supported devices, I noticed a reference to Back-UPS BX****MI Series, which mentions it may require additional tweaks since 2023.

My UPS uses a cable Ethernet to USB and is typically monitored with PowerChute. From what I’ve seen, other Back-UPS models use the usbhid-ups driver, but I would like to confirm if this applies to my specific model. Additionally, I would like guidance on whether I need to set any extra parameters such as:
• lbrb_log_delay_sec=N
• lbrb_log_delay_without_calibrating
• onlinedischarge_calibration

I would greatly appreciate confirmation on the compatibility of my model and guidance on which driver and settings I should use with NUT.

Thank you in advance for your support.

Best regards
