Home automation tip: Always have a manual override. Tech fails, switches don't! Every smart switch has physical button. WAF (Wife Acceptance Factor) is critical. Automations enhance, not replace basic functionality. Learned this the hard way during a WiFi outage. Smart home humility! #homeautomation #reliability #iot #protip
