Warning from HB

HB-DA now generates a warning from HB:

[3/31/2022, 12:34:49 PM] [homebridge-daikin-airbase] This plugin slows down Homebridge. The read handler for the characteristic 'On' didn't respond at all!. Please check that you properly call the callback! See https://git.io/JtMGR for more info.

The platform always calls the callback method when responding to characteristic read requests, so I am not seeing any problem. Do you have any extra details about when this occurs?

[cemilbrowne]

No more detail - these seem to be scattered through the logs at the moment on 1.4.0. No additional useful context that I can see. Want a screenshot of the logs?

Thanks!

[yenoiwesa]

@cemilbrowne is this still occurring?

[yenoiwesa]

Closing as no response. Feel free to reopen.

[cemilbrowne]

Hi, don’t see these in the logs at the moment. Will reopen if I do. Thanks.

[cemilbrowne]

Just as soon as I thought we were good...

[9/2/2022, 6:59:56 PM] [homebridge-daikin-airbase] This plugin slows down Homebridge. The read handler for the characteristic 'Current Temperature' was slow to respond! See https://homebridge.io/w/JtMGR for more info.

I wonder why...

[cemilbrowne]

@yenoiwesa I don't have privs to reopen issue - but definitely still recurring. Can I help troubleshoot?

[yenoiwesa]

@cemilbrowne I reopened it.

This problem has never occurred to me. The read handler is what interrogates the Airbase module to get the temperature/mode settings. The plugin is entirely stateless and relies on the Airbase for its state (the source of truth). The only way it could be slow to respond is if you have a slow home network, or if the airbase itself is slow to respond.

Have you tried rebooting the Airbase module see if it helps in any way?

[cemilbrowne]

Interesting - is there a way to log the URL called for interrogating state of the airbase? I assume this is just on/off state - if I can test the URL manually, I can see if it occasionally takes a while to respond...

Network should be fast - HB is on a hardwired server, airbase is wifi, but quick (they're sitting right next to an AP for crying out loud!).

I could imagine that maybe the airbase module goes to sleep - or even changes DHCP IP potentially - and that's causing it?

[yenoiwesa]

If you restart homebridge in debug mode (-D) it will log this line that shows you the URL it queries: https://github.com/yenoiwesa/homebridge-daikin-airbase/blob/master/src/airbase-controller.js#L134-L141

I could imagine that maybe the airbase module goes to sleep - or even changes DHCP IP potentially - and that's causing it?

Potentially but then it's weird that this would not happen to other users 🤔

[cemilbrowne]

OK; I've got the URL now - I'll set up a running curl every few seconds to test it.

For others who might want to test:

ret=OK,pow=0,mode=1,operate=1,bk_auto=2,stemp=23,dt1=23,dt2=20,f_rate=3,dfr1=3,dfr2=3,f_airside=0,airside1=0,airside2=0,f_auto=1,auto1=1,auto2=1,f_dir=0,dfd1=0,dfd2=0,filter_sign_info=1,cent=0,en_cent=0,remo=2
curl http://x.x.x.x/skyfi/aircon/get_control_info  0.00s user 0.00s system 4% cpu 0.143 total```

[yenoiwesa]

@cemilbrowne any update on the curl you setup to monitor the successful/failed connections to the Airbase?

[manningoz]

I am getting the same error now.

I have had this issue fairly frequently too. I've switched HomeKit to run in debug so I can try and capture anything else. It's likely to be a slow response from the unit itself.
