Past Logs v1
Past Logs give you a opportunity to look into the past to for a limited picture of activity happening in your hub. While Past Logs are a possible way to troubleshoot your devices to see if automations are firing or check for errors, it's important to remember that past logs automatically purge when the buffer size limit has been reached.
It is best to open your logs in a separate window so you can watch them while you work on the Hubitat Web Interface in a second window. Your logs start as a blank window, but data will begin to appear as your devices check in.
