Thanks a lot for the bug report! I have added a check for the existence of 'wicksts' when dumping the filter status. Please let me know if it works, so I can release a new version on PyPI.
Works 👍
Thanks!

No but I'd love to hear your motivation for this :)
I'm not an expert on this matter but most "smart" devices are based on ARM-based chips running linux (or Espressif's ESP SoCs running RTOS). With the ARM based systems usually it's quite simple to find a TTL-UART on the board and usually you get a root shell or at least access to U-Boot (the bootloader).
For example: WiFi IP Webcam, hunderts of different variants available, this one was top 3 on German Amazon

Or android running TV boxes from china: https://imgur.com/a/vuRzXrP
Some people at https://www.armbian.com/ also build distros (based on Debian or Ubuntu) so one can use those TV boxes just like "regular hardware" guaranteed free of non-free/open source code.
The Philips ACs seem quite simple (maybe just some digital GPIO?) it may be possible to create a 100% open source firmware or at least find some binaries to binwalk
. That said, given they are expensive I wouldn't risk to destroy a "productive" unit. I'll keep my eyes open on eBay for broken/cheap used devices…

This is great idea! I am pretty sure the firmware can be updated and we can exploit this functionality to replace it with open-source firmware and remove the phone-home crap. I will open a new issue to track this.
Thanks for this great tool and reversing the proprietary crap :-)
I've just started using it with the AC2889/10. The filters flag causing an error:
A3 is the "NanoProtect Filter Series 3" FY2422 (HEPA) , C7 means "NanoProtect Filter AC" FY2420 (activated carbon). The time of "fltsts0" is probably referencing to the user cleanable "prefilter" of the AC2889 which has no humidifier function (so no "wicksts").
