Wrap WiFi connection code in a function.

Add `is-lamp-on` endpoint for pico to check.

This could be a status endpoint which returns on or off { "status": "on" } or { "status": "off" }.

Switch status change causes lamp toggle.

Update code so that change in switch state causes toggle of lamp status. This will help with user experience since they could use web app or switch to toggle the lamp.

Current code has lamp on when switch is on.

Add LED for status connection WiFi.

Write some tests.

Remote LED assumes current state of switch at startup.

1. Read state of 14-Control
2. Send HTTP request to set lamp to proper state

Add LED for status system restarted.

Determine and implement `OFF` status LED logic.

Determine and implement `ON` status LED logic.

Add LED for status turn light off.

Refactor `led_fast_blink` to `led_blink`.

Current

def led_fast_blink(led, cycles):
    for _ in range(cycles):
        led.on()
        sleep(0.1)
        led.off()
        sleep(0.1)

New

def led_blink(led, time_diff=0.1, cycles=2):
    for _ in range(cycles):
        led.on()
        sleep(time_diff)
        led.off()
        sleep(time_diff)

Determine and implement WiFi status LED control.

Possible Functions

def update_wifi_status():
    # ...

Add LED for status turn light on.

Separate 'reset' LED into a 'shutdown' and 'starting' LED.
