My internet has been down for approaching 24 hours. Lessons learned: Thank heavens for Edge; my locally executing drivers and routines are working great for heating, hot water, and some lighting. I rely on Amazon Echo for too much of my control and automation. I should have kept fresh batteries in all my buttons and dimmers; after replacing batteries in my Ikea buttons and dimmers, I always have to re-pair them; too late if I do not have internet. Bulbs that do not remember their last state are useful; just cycle the power to switch them on (but you have to leave them off afterwards). Bulbs that remember their state are not so useful in this case. Ikea dimmers that ‘steal’ devices from my SmartThings hub using touch sync are sometimes useful (See @JDRoberts clarification of TouchLink below). After finally convincing my wife that smart lighting is a good idea; I have some more convincing to do (after we get our internet back). Cable fiber to the property is a great thing; until somebody breaks the fiber. Just my thoughts.
