As per my previous post, since the Google Home app is inherently unreliable for detecting and reporting on the status of Google's pods, I've found that there are some APIs that worked with the first generation Google Wifi products that continue to work with the Nest Wifi pro pods. The most useful one appears to be:
There's information on this API here: https://gist.github.com/Zenexer/e1c03b87fee6236c71e4fefcb1ff73a9#request-9
It returns a JSON file in the format below (testwifi.here appears to resolve to the IP address of the pod that is acting as the router. You can substitute it with the IP addresses of your other pods and get a similar result. I've highlighted in bold two key attributes that are worth tracking. If you use Google Chrome, you can install an extension that makes it easy to call this API and get the status: https://github.com/semenko/chrome-status-monitor-for-google-wifi

}Here is a Python script that will poll your pods every minute, writing the status result (and a timestamp) to a log file (change {yourid} to where you want to run the script & have the log files be stored). Update the device_ips to the IP addresses of your pods (if not running this on a Mac, then you can comment out the line that sends a Notification (osascript😞

schedule.run_pending()
time.sleep(1)
log files are named 192.168.86.1.log, etc. Here's a second Python script that reads these log files and looks for when the online attribute is no longer True or when the led indicates it is no longer connected ledAnimation ≠ CONNECTED (for my two pods that are acting as bridged access points with backhaul via ethernet, the ethernetLink attribute is reporting False, so that attribute can't be relied upon to report when that link appears to be down):

import os
import json
from datetime import datetime
log_folder = "/Users/{yourid}/Documents/Programming/Python/Nest"
for log_file in os.listdir(log_folder):
if log_file.endswith(".log"):
with open(os.path.join(log_folder, log_file)) as json_file:
for line in json_file:
timestamp, json_str = line.strip().split("]", 1)
json_data = json.loads(json_str)
log_time = datetime.strptime(timestamp[1:], "%Y-%m-%d %H:%M:%S.%f")
if json_data['system']['ledAnimation'] != "CONNECTED" or json_data['wan']['online'] != True:
print(f"Error: Device {log_file} status is not as expected at {log_time}")
If anyone knows of a better way to do some monitoring/logging--please let me know.
