Add support for Lomediqi Fresh air system

[DaddyTommy69]

Device model bjdm.airfresh.test01

Device name Lomediqi Intelligent Fresh air purifier

Does the device require a MiCloud connection? Do not know (released in 2019 I think according to this page https://home.miot-spec.com/s/bjdm.airfresh.test01)

Anything special about the device?

• Please support adjusting fresh air level (ranges from 0-20%-40%-60%-80%-100%) and C02 sensor in addition to the standard air purifier controls
• There are 2 versions of the device (one with ioniser and one without). I believe both goes by the model of bjdm.airfresh.test01

Hi, what is not working with the device currently? Did you already try to add it to the plugin?

[DaddyTommy69]

My apologies I recently press discover devices in the plugin and it's been found and working in homekit. However I do wish for a fresh air level option alongside the fan speed option, as the device has 2 fans that operate independently (the top one is for room air intake and bottom one for fresh air intake). I will post the pic of the Xiaomi Home controls below

Controls for the top fan (room air intake)

Controls for the bottom fan (fresh air intake)

Hi, you would need to use propertyControl to expose the missing functionality.

[DaddyTommy69]

I managed to find what I want to control but not sure how to input them. Please point me in the right direction

[merdok]

You just have to enter the property name in the required field.

It is showing up as individual switches for 0-1-2-3-4-5 level. Is it possible to turn it into the blue slider for fans

[merdok]

Not in a generic way because the property is marked as a value list with a couple possible values, currently you can only show things like this with multiple switches.

It would be greatly appreciated if you could find the time to implement such function. It is one of the main selling point of the unit as opposed to much pricier alternatives. Thank you

[merdok]

It requires a special property handling currently for this particular device which would require some work. Maybe it could be emulated using a fan or lightbulb but that would still require some code adjustments. The main problem here is that HomeKit does not support such ui control which allows to select between multiply options hence we need to do some tricks in order to make it work...

You can also limit the values only to those switches which you use the most, so if you just use two values then you can create two propertyControl for the same property and you can specify the value it should set, that way only two switches will appear.
