[Bug] Alarm: Wait for countdown before ringing

[ThomasTJdev]

When the nimha_gateway receives a message with a trigger, it starts the trigger proc asyncCheck alarmTriggered(). Inside the trigger proc, I would like to run a loop with await sleepAsync. The loop needs to break, if the user changes the alarm status from triggered to disarmed. If the user does not change the alarm status before the countdown time, the loop will set alarm status to ringing and break.

But using await inside this proc does not work. The await never finishes - therefore the alarm will never start ringing.

Trigger proc

proc alarmTriggered*(db: DbConn, trigger, device: string) {.async.} =

Await tries inside the trigger proc

# One of many tries
proc alarmTriggerTimer() {.async.}  = 
  var counter = 0
  while true:
    waitFor sleepAsync(1000)
    inc(counter)
    if counter == countDownTime or alarmStatus != "triggered":
      break

var f = alarmTriggerTimer(countDown)
while not f.finished:
  poll(1000)
    
if f.finished:
  if alarmStatus == "triggered":
    asyncCheck alarmRinging(db, trigger, device)

# Another try
var counter = 0
while true:
  await sleepAsync(100)
  inc(counter)
  if counter == countDownTime and alarmStatus == "triggered":
    alarmRinging(db, trigger, device)
    break
  elif counter == countDownTime and alarmStatus != "triggered":
    break
