Have anyone of you seen any excessive data downloads from Hass.io? My Hass.io install on rpi3 have downloaded 865 GB in less than a month, a couple of the days the download was close to 90 GB. Yesterday I removed cloud and HomeKit integration and now it is down to ‘only’ 11.5 GB in the last 24 hours. Any help on how I can figure out what’s going on would be greatly appreciated.

What components are you using?
Is this from the built in HA sensor giving the traffic total or something else?
I found the issue in the Google Wifi app. It keeps track of the download and upload by device.
The components I’m currently using:
- Philips Hue
- Lutron Caseta
- WeMo
- Nest Thermostat
- Arlo Pro Cameras
- MQTT Bridge to SmartThings
I disabled the cloud and homekit integrations, and now it stays pretty consistent at about 0.5 GB per hour. Still a lot, but not close to what I experience before.
how much are these transmitting?
Is this total traffic? WAN traffic, LAN Traffic?
It is all WAN traffic.
My next step is to disable the Arlo cameras in the config and, maybe the MQTT.
Can you monitor real time? I would get a baseline and then disable some components and see if there is a large drop.
Does your router allow you to see where traffic is going? If so it should be easy to monitor the PI traffic and see what IP its downloading from, use an IP lookup tool to see the source. (doesn’t always work as so much is hosted on amazon servers these days)
I have not found a way to see where the traffic is coming from on the Google Wifi. I will disable anything that might connect to the internet, and then enable one by one…
No, I’m not using any of those components.
This morning I removed the following components from the configuration:
cloud:
homekit:
arlo:
I also unplugged the SmartThings hub. For the last 3 hours there have been virtually no bandwidth usage, so I will add them back one by one when I get back home this evening to see what service caused the issue.
Thank you for taking the time to help out 
What are your internet speeds mb up/mb down for reference?
I think it is 120 Mbps down, and 12 Mbps up…
Here are the usage for the last 30 days, and the last 24 hours from Google Wifi router if anyone is interested.
That’s about 7mb or so down/minute right?
What’s an image download size for camera component?
If it a 1mb image fetch for single or multiple camera from remote server and refresh and pull every 10 seconds that may be all it take.
EDIT
I look at image from Camera and size is about 60kb/image.
Anyone know an average HA data use?
@silvrr, Thanks for helping out! I followed your advice and disabled all suspects… then enabled them one by one.
@tmjpugh, Thanks… you were spot on, it was the Arlo cameras that was the culprit.
Everything is enabled again, except for the Arlo cameras. I’ll move them back to the SmartThings hub and connect to them using MQTT instead. They actually worked better that way since with SmartThings they were pushing events, instead of hass having to pull.
Here’s a screenshot from my tests today. The spike between noon and 4 PM is when I re-enabled the Arlos.

In my case it was a speedtest running every hour.
