• set_favourite_speed 0...150
• get_sensor [sensor] pm25/co2 (at the mihome app pm25 values above 999 are capped to 999)
• set_ptc_on [on/off]
• get_timer []
• get_ptc_timer []

• set_filter_reset [filter]

Supported properties:

• pm25
• co2
• temperature_outside
• favourite_speed
• filter_rate
• filter_day
• control_speed
• power
• mode
• ptc_on
• ptc_status
• child_lock

Getter and setter of ptc_level and screen_direction is not supported!

Example get_prop response:

$ miiocli device --ip IP --token TOKEN raw_command get_prop '["power", "pm25", "co2", "temperature_outside", "favourite_speed", "filter_rate", "filter_day", "control_speed", "ptc_on", "ptc_status", "child_lock", "sound", "display", "mode"]'
Running command raw_command
[True, 2, 554, 12, 150, 45, 81, 60, False, False, False, False, False, 'auto']

Filters on this device have RFID-tag, so the device knows itself when the filter is being changed. So method set_filter_reset does not work at all.
Range is 0-150 for set_favourite_speed.
Also, this device accepts true/false instead of on/off, just like dmaker.airfresh.t2017 model does: rytilahti/python-miio#854

@skvalex Are you aware of this command (rate vs reset) to reset the filter lifetime: rytilahti/python-miio#662 (comment)

[skvalex]

@syssi I don't have access to this device now, but I have played with it in January and have added support for openhab then.
So, according to the config I created, filter_rate is for filter life remaining in percents and filter_day is for days remaining.
As I said before, set_filter_reset doesn't work there at all, so it can be removed completely. At the time of writing config for openhab I couldn't test it, because the filter was 100%, that's why set_filter_reset exists in my config.

Hey guys

Any news on this one? Is there anything I can do to help this going (e.g. provide logs, debug, test, etc)?

I've got this device and would really like to integrate it into HA.

Hey @syssi

Sorry for being annoying here. Just trying to figure out if I can do something to help finish this up and get merged.

[syssi]

The next step is to prepare a python-miio release. As soon the new version is released this PR can be merged.
