We bought a new house a few years ago right as Insteon was collapsing and I
kind of put a pause on what to load the new place with. I had misguided
high hopes for Matter device and still don't have anything that looks as
good as Insteon.

I've finally added more Insteon gear and after giving HA and OpenHAB a run,
nothing deals with Insteon as well as Misterhouse.


So I've started down the rabbit hole of making MH do everything insteon and
HA for modern creature comforts like HomeKit, etc.

HA has it's own quirks with Fans, specifically if you want a
off/low/med/high slider to show up you need to tell it the fan only has 4
states, but then the 0-100 range needs to be mapped to 0-3.

As I keep going down the hole it turns out the MQTT code in MH doesn't
support "FAN" as a type. I intend to build this in, eventually. For now
though I exposed the fan as a dimmable light, and deal with the unfun on
the HA side.

If this helps anyone at this point, I created the fan as a normal light,
with discoverable disabled, and then used MQTT Explorer to add the
autodiscover record by hand. Here's all the magic

{
  "unique_id": "insteon_51D36002",
  "name": "Master Bed Fan",
  "state_topic": "insteon/mbr_fan/state",
  "percentage_state_topic": "insteon/mbr_fan/state",
  "schema": "json",
  "command_topic": "insteon/mbr_fan/level",
  "percentage_command_topic": "insteon/mbr_fan/level",
  "platform": "fan",
  "state_value_template": "{{ value_json.state }}",
  "percentage_value_template": "{% if value_json.brightness == 100 %}3{%
elif value_json.brightness >= 50 and value_json.brightness <= 99 %}2{% elif
value_json.brightness >= 1 and value_json.brightness <= 49 %}1{% elif
value_json.brightness == 0 %}0{% endif %}",
  "command_template": "{ \"state\": \"{{ value }}\"}",
  "percentage_command_template": "{ \"state\":\"{% if value > 0 %}ON{% else
%}OFF{% endif %}\",\"brightness\":{% if value == 3 %}100{% elif value == 2
%}75{% elif value == 1 %}25{% elif value == 0 %}0{% endif %}}",
  "speed_range_max": "3"
}


I'm hoping to genericise most of that into the MH config where you'd be
able to define if you want a fan to act like a 4 speed fan or variable
(0-100%)
