I've got 11 TP-Link smart plugs and 2 smart bulbs scheduled on my KASA app for androind. Last night everhything functioned as it should - lights turned on and off per schedule and I was able to access via Amazon Alexa to turn lights off/on This morning - nothing. Everything comes up as "device unreachable". My wifi network is fine - I'm able to stream live TV through the Apple TV and have normal web access for business - only my smart plugs / bulbs are offline. I've uninstalled and reinstalled the app with no success. Frustrating.
