Set range of fan speeds

[radiocolin]

I think the HomeKit API allows this, and if so, it would be great if we could specify the range of fan speeds as a configuration element, rather than only having 0-100. My fan uses 1 to 6 for its speeds.

I would like this feature as well. I have a tasmota fan and have different speeds that can be read/set via different payloads.

Homekit doesn't like having its minimum and maximum rotation speeds set to ranges very different to 0-100. I would instead recommend something like:

        {
            "type": "fan",
            "name": "Test Fan",
            "url": "mqtt://192.168.10.35:1883",
            "logMqtt": true,
            "topics": {
                "getRotationDirection": "test/fan/getRotationDirection",
                "setRotationDirection": "test/fan/setRotationDirection",
                "setOn": "test/fan/setOn",
                "setRotationSpeed": {
                    "topic": "test/fan/setRotationSpeed",
                    "apply": "return 1 + Math.round(message/20)"
                }
            },
            "integerValue": true,
            "accessory": "mqttthing"
        }

... to convert the standard 0-100 range to 1-6.

Thanks so much for making this change. It works great with Tasmota and I can remove a dedicated plugin now! Here's my Tasmota config in case anyone comes looking for one:

        {
            "accessory": "mqttthing",
            "type": "fan",
            "name": "Lounge Ceiling Fan",
            "topics": {
                "setRotationSpeed": {
                    "topic": "cmnd/loungefan/fanspeed",
                    "apply": "return (Math.round(message/100*3))"
                },
                "getRotationSpeed": {
                    "topic": "stat/loungefan/RESULT",
                    "apply": "return (Math.round(JSON.parse(message).FanSpeed/3*100))"
                }
            }
        },
