First thing I noticed was that every day when I came home from work, the motion sensors didn’t work anymore and my RasPi wasn’t accessible anymore. I’ve put a daily reboot into cron which helped a bit, but still over the run of a day the whole thing stopped working.
A bit later I noticed that my network was very sluggish, streaming Netflix was very low quality and stalled a lot, and in a game I got lots of disconnects, like every few minutes.
This weekend I went out on a limb and pulled the plug on my homeassistant-RasPi – not a single disconnect since then.
Let’s go back a few days:
I turned off https since I had the impression it slowed everything down.
I saw lots of errors concerning eq3bt about not being able to reach components, so I commented that one out, too.
Netatmo integration gives a lot of python errors in the logfile, but I haven’t turned that off so far.
Oh, and my Google Home is off power since last week, just to be sure.
So far the network is calm and runs nicely.
I’m really not sure what could cause my problems. A look into /var/log/messages doesn’t show any problems. Hmmm…
Two external possibilities, firstly Google have dropped the ball with Homes and Chromecasts breaking networks, check the media for details, and is your router up to the job of all the extra devices and traffic you’ve added?
The Google Home was switched off for a few days now. I did that on purpose to rule out those chromecast broadcasts. So Google home can be ruled out as the culprit.
I didn’t add any devices recently, on the contrary, I’ve removed features from configuration.yaml, exchanged all Osram lightbulbs by Philips Hue and removed osram_* from configuration.yaml - overall I made my setup much simpler.
Problems started last week, which I am unable to connect to any changes. Not even a HA update. Very strange.
Yes, I do have router based presence detection. But I am using it since about 3 months, and had no problems until now. But technically you surely are right - this will result in a lot of traffic and will slow down the router. I’ll give it a try and disable it.
Maybe try to see what’s going on your network using Wireshark.
You’ll be able to see which device send the most packet on your network and see if home-assistant is creating too much traffic and also what kind of traffic + to which device it is sent.
I’ve disabled the router device presence detection. So far the network isn’t sluggish anymore, but I’ve had a three complete connection drop offs yesterday. I need to investigate more…
