Check PagerDuty on your ESP8266 and SSD1306 powered display
I use an ESP8266 Chip with Wifi and an 0.96" OLED display with SPI to display open incidents on PagerDuty.

Within the code you need to add PagerDutyDomain and PagerDutyToken with your PagerDuty settings. Compile it, deploy it, setup Wifi and be happy
