Running fauxmo with hundreds of devices #112

Closed neodesc closed 2 years ago

neodesc commented 2 years ago

My Issue

I've been running fauxmo with the command line plugin for a couple of years now with no issues. However I'm adding a lot more devices (~250) in the config.json file now and its not working anymore: device unresponsive. The Echo discovers them correctly but it just can't use them most of the time.

WHYT

Reducing my list of devices. Managed to get it from over 900 to ~250. It works great with 50 but I need 250 because my KNX devices are not alexa compatible and I need a "commandline device" for each real device property. For instance a blind has 10 positions + its slates.

Please make sure you've taken these steps before submitting a new issue:

Wow!

I'm blown away that you're using this with so many devices.

I'll need to think about it, but honestly this part makes me think it might be an issue on the Echo side (emphasis mine):

The Echo discovers them correctly but it just can't use them most of the time.

Because fauxmo is all asyncio based, I would think it could handle hundreds of devices without issue.

I'll almost certainly need some debug output. Can you capture and post a verbose / debug log during a failed attempt to trigger a device?

Bump.

This issue is pending a response and is blocked until I have more info. To keep the issue list groomed, I will often close these stalled issues if they go a prolonged time without a response. In this case, I will give it another week or so.

@neodesc You might try the dev branch; I've added a few lines to support running on uvloop, which has much better performance than the built-in event loop. It might make a difference in your case of being able to handle hundreds of devices.

$ source venv/bin/activate
$ python -m pip install uvloop
$ python -m pip install git+git://github.com/n8henrie/fauxmo.git@dev

Hi Nathan,

I’ve been using your regular main code. Figured out as long as I have less than 200 devices everything works just fine.

I’ll keep the dev branch in mind though for possible future setups. Thank you very much for your help :)
