Four Channel WiFi Relay Timer

General purpose application to control the four channel WiFi enabled ESP-01 based relay units with optional timer function.

Once connected to a WiFi relay unit based on the ESP-01 controller you can individually switch on and off the relays as well as create a sequence of timer controlled actions (current maximum: 12). The timer increments every 50 milliseconds, however please note this not 100% accurate, on tests it was averaging 62 milliseconds on my laptop.
New feature added to generate a single pulse on any of the outputs with a configurable on/off period.
For test purposes you can run the app without an ESP-01 relay unit connected, click on the "Device IP Address" text to toggle network operation. (Black text: enabled)
