Error connecting to a Philips 1214/60 via HTTP and CoAP

[vihung]

I have a Philips 1214/60 air purifier. I have set it up according to Philips's instructions - it is connected to my WiFi network and the Philips CleanHome+ app on my iPhone. I have not created a Philips login (yet) and it is working on my local network.

The app shows my device firmware version as 2.0.0, and wifi firmware version as 59.

My router shows me the IP Address of the purifier as 192.168.4.97

I am on a Mac (Mid-2011 Mac mini running macOS High Sierra 10.13.6).

I have installed python3 using Homebrew.

$ python3 --version
Python 3.9.13

I have installed py-air-control using PIP

sudo pip3 install py-air-control

Attempting to connect to the device using airctrl gives me an connection error.

Via HTTP;

$ airctrl --ipaddr 192.168.4.97 --protocol http

Exchanging secret key with the device ...

What can I do to make this work?

My overall intention is to use the homebridge-philips-air plugin for Homebridge, which in turn uses py-air-control.

[rgerganov]

The error you get when using CoAP is due to a bug in the coap library. I have fixed this in my Coapthon3 fork here: https://github.com/rgerganov/CoAPthon3/commit/21243904be7794dbea1857dc2d5724a344e35548

Install my fork like this:

pip3 install -U git+https://github.com/rgerganov/CoAPthon3

and then try again

[vihung]

I had missed a step in my above comment. I had previously installed a specific CoAPthon version - using sudo pip3 install -U git+https://github.com/Tanganelli/CoAPthon3@89d5173 (according to instructions at https://github.com/NikDevx/homebridge-philips-air). I will try your specific fork and report

[vihung]

I have installed the specific fork mentioned above

sudo pip3 install -U git+https://github.com/rgerganov/CoAPthon3@2124390

and then tried running airctrl. I still get an error

$ airctrl --ipaddr 192.168.4.97 --protocol coap

[vihung]

Looking at your change (https://github.com/rgerganov/CoAPthon3/commit/21243904be7794dbea1857dc2d5724a344e35548), and looking at the error above ('Thread' object has no attribute 'isAlive'), it looks like some change has not stuck (is_alive vs. isAlive). I will investigate further.

Do I need to explicitly uninstall the previous other version of CoAPthon before installing yours?

(I am unfamiliar with most of this technology stack, although I am somewhat computer-savvy otherwise)

[vihung]

Yes. I can confirm the change had not stuck. I manually changed the isAlive() to is_alive().

sudo nano /usr/local/lib/python3.9/site-packages/coapthon/client/coap.py

and I now get this.

Thank you so much for your help!

Can you please let me know what I need to do to uninstall and reinstall the specific version of CoAPthon?

[rgerganov]

Good to hear it works. Managing python dependencies is a mess, sorry cannot help here.
