How to Reproduce / 复现步骤

1.打开风扇界面 只能调节25 50 75和100 不能无级调速
米家1x落地扇。设备为dmaker.fan.p5c
2.注意到下面有一个风速档位，那个是可以无极调节的，但在风扇实体里却不能无级，导致在homekit里也无法无极调节。

Expected Behavior / 预期结果

应该可以是任意百分比的风扇速度

Hi @qiyueliu, same issue here with the dmaker.fan.p5 — just found the root cause and submitted a fix.

Root cause: The MIoT cloud spec describes the continuous speed property (piid=6, service 2) as a 4-item value-list (values 1–4). The fan entity uses this value-list, so setting 100% sends value 4 to the device (which the device interprets as 4% speed), giving only 4 discrete steps instead of continuous control.

Fix: Override prop.2.6 with value-range: [0, 100, 1] in spec_modify.yaml so the integration treats it as a continuous 0–100% speed property.

PR for dmaker-p5: #1714

For your dmaker.fan.p5c, the fix is likely the same — could you check what siid and piid your continuous "风速档位" number entity uses? (It's visible in the entity ID, e.g. p_2_6 means siid=2, piid=6.) If it's also service 2, property 6, the same fix applies and I can update the PR to include p5c.

Workaround in the meantime: Add this to custom_components/xiaomi_home/miot/specs/spec_modify.yaml on your HA instance (adjust the URN version number if needed), then check "Update entity conversion rules" in the integration config:

urn:miot-spec-v2:device:fan:0000A005:dmaker-p5c:1:
  prop.2.6:
    value-range:
    - 0
    - 100
    - 1
