I think I resolved it, I copied xiaomi_miio to custom components and changed in __init__.py several parameters: I set POLLING_TIMEOUT_SEC to 90, UPDATE_INTERVAL = timedelta(seconds=40) seconds to 40 and added my two devices to LAZY_DISCOVER_FOR_MODEL, like this:

LAZY_DISCOVER_FOR_MODEL = {
        "zhimi.fan.za3": True,
        "zhimi.fan.za5": True,
        "zhimi.airpurifier.za1": True,
        "dmaker.fan.1c": True,
        "roborock.vacuum.s5": True
    }

I guess it can help to other devices too
