Humidifier Dehumidifier can't send HexCode
It's difficult to set fanSpeed exactly with Home APP .

As Fan type.
My code 
`"data": {`
`  "on": "code_ON",`
`  "fanSpeed10": "code_10",`
`  "fanSpeed40": "code_40",`
`  "fanSpeed80": "code_80",`
`  "fanSpeed100": "code_100",`
`}`
I want to set my fanSpeed to 80. 
With Home APP , I only set fanSpeed close to 80.

If I want to set fanSpeed to 80 ,but I will set it to 75 with Home APP .
It can send close to FanSpeed80 HEXCode.

My log
`[Broadlink RM] My Fan setFanSpeed: 75`
`[Broadlink RM] My Fan setFanSpeed: (closest: 80)`

But Humidifier Dehumidifier type can't to do as fan type.

Thanks
