Ping performance changes after every reboot

[dpremo-ul]

The problem

I've seen this going on for at least several months. I wouldn't be surprised if it was happening before I noticed.

I have a Binary Sensor set up to track whether my HA has access to the internet. (I used to manage this in yaml but I think that's no longer supported. I think it pings 8.8.8.8 but I can't find where to verify that.)

I also have a sensor set up like this (I transcribed it so apologies if typos):

- platform: template
  sensors:
    ping:
      friendly_name: "Ping Average"
      unique_id: ping_average
      unit_of_measurement: 'ms'
      value_template: "{{ state_attr('binary_sensor.internet_connectivity', 'round_trip_time_avg') }}"

Here's the problem: Every time Home Assistant reboots -- whether because I update it or because of a power outage -- Ping Average performance is different. This is difficult to describe, so here's a screenshot:

In the image, I have History cards for 'Last 60 Minutes', 'Last 8 Hours', and 'Last 14 Days'. The 'Uptime' graph shows Home Assistant's uptime. Color change in this graph indicates that Home Assistant rebooted. The 'Ping Average' graph shows the Ping Average sensor.

In the 'Last 60 Minutes' card, you can see that from 9:48 AM to about 10:05 AM, Ping Average hovered around 15ms with steady spikes of about 65ms. Around 10:05 AM, the power goes out momentarily and Home Assistant reboots. (There's not enough time before the next reboot to spot a trend here.) Around 10:11 AM, power goes out again, and Home Assistant reboots. Here we have a new trend: Ping Average hovers around 15ms, but the spikes now max out at 30ms, and sometimes the spikes last longer.

In the 'Last 14 Days' card, more trends can be seen, and more HA reboots can be seen. Each time HA reboots, there is a different trend.

This suggests that none of the data is reliable. Why does Ping Average swing so much each time Home Assistant reboots?

I'm not sure if this is the same issue, but every time I reboot HA, all my ping integrations (a few local IP addresses and some on Internet) fail intermittently for about 2-3 hours, before stabilizing.

Thanks @bdraco. I have found my issue, and it wasn't caused by the Ping integration, even though it was the only sign that something wasn't right.

In case others are in the same boat: I had performance issues (with the Ping and also when browsing HA) due to a custom component, namely https://codeberg.org/raboof/ha-gpio, which I have replaced with https://github.com/jdeneef/ha_gpiod and that fixed my issue.
