I’m in the market for a battery-powered, Wi-Fi connected programmable sign. I want to attach it to my office door so that I can tell my family (well, mostly my kids) when its OK to enter, and when I need silence. Any ideas?
I just saw this one...also using an ESP8266. instructables.com/id/WiFi-Work-F… If you want to do something similar I have a particle core I can out in a box on the stoop for you to pick up. WiFi out of the box with OTA firmware flashing that's dead easy to ping remotely.
