Hi @psg99
Welcome to the community!
If your environment is particularly prone to routine Wi-Fi congestion and you would like to "automate" Network Optimization, I'd recommend trying the Reboot Schedule feature — How to configure the Reboot Schedule feature on Deco.
Upon reboot, your Deco will restart its Wi-Fi module and check if switching to other channels is needed based on the current wireless environment, effectively achieving the same result as automating Network Optimization.
Additionally, from what I understand, an added benefit to rebooting your Decos is that it also helps clear the system's memory/cache, which is a generally recommended troubleshooting step if you're experiencing network anomalies due to environmental factors like Wi-Fi congestion.
For example, I have my Decos scheduled to reboot weekly in the very early hours of Sunday morning. I feel like it has helped with keeping some of my more stubborn smart home devices in check.
