Alarm Conditions - Help

[Wessel]

Hi,

I seted up some alarms to tweet in certain conditions. All are one-time alarms, but I'm not sure if they are 100% right. I want that they be triggered when raise conditions is reached and every day, they must be cleared at midnight. Let's see some of them:


Tweet when actual temperature is below then 5ºC:

Raise:

Code: Select all

([th0temp-act=c.1:0] <= 5.0)

Clear:

Code: Select all

([th0temp-act=c.1:0] > 6.0) || (([hh] = 0) && ([mm] = 1)) 

Message: FRIO | Temperatura atual no bairro Languiru, em Teutônia, já está abaixo dos [th0temp-act.1:--] °C.

I have one more for temperature below 0ºC, higher than 35ºC, 38ºC, heatindex higher than 40ºC, 45ºC and th11 below 0ºC.

Tweet when UV index is higher than 8:

Raise:

Code: Select all

([uv0index-act.1:0] >= 8.0)

Clear:

Code: Select all

([uv0index-act.1:0] < 7.0) || (([hh] = 1) && ([mm] = 0)) 

Message: RADIAÇÃO UV | Atenção, radiação UV MUITO ALTA (Superior a [uv0index-act.1:--] uvi) agora em Teutônia. Evite ficar exposto ao sol entre o horário das 10h às 16h. Camisa, protetor solar e chapéu são uma obrigação.

I have one more for UV index higher then 11.

Another for low pressure:

Raise:

Code: Select all

([thb0seapress-act.1:--] <= 1000.0)

Clear:

Code: Select all

([thb0seapress-act.1:--] > 1005.0) || (([hh] = 1) && ([mm] = 0)) 

Message: ([thb0seapress-act.1:--] > 1005.0) || (([hh] = 1) && ([mm] = 0))

For wind speed:

Raise:

Code: Select all

([wind0wind-act=kmh.0:0] >= 40.0)

Clear:

Code: Select all

([wind0wind-act=kmh.0:0] < 30.0) || (([hh] = 1) && ([mm] = 0))

Message: VENTO | Vento forte no bairro Languiru. Rajadas superam os [wind0wind-act=kmh.0:0] Km/h.

For rain rate is my great doubt:

Raise:

Code: Select all

([rain0rate-act.0:0] >= 25.1 & <= 50.0)

Clear:

Code: Select all

([rain0rate-act.0:0] == 24.0 || (([hh] = 1) && ([mm] = 0)) 

Message: CHUVA | Chuva forte no bairro Languiru. A taxa de precipitação é de [rain0rate-act.0:--] mm/h.

I want to tweet for differents scales of rain rate, like light rain, heavy rain, etc.

Is there anything wrong with my raise and clear conditions?

[Wessel]

i'm making some tests with those onte-time alarms, like this one:

Code: Select all

Raise: ([th0temp-act=c.1:0] >= 18.1)

Code: Select all

Clear: ([th0temp-act=c.1:0] < 17.0) || (([hh] != 00) && ([mm] != 01))

What I noticed is that I receive an e-mail every hour, like 15:01; 16:01, 17:01 when the temperatur is above 18.1°C and I though that the clear condition would work when temperatura is under 17°C or everyday at 00:01. What's wrong?

When I check the "i" icon, instead to see "||" there is only "|".

| and || are equivalent, they are both logical operators (not bitwise).

Ok, thank you.
And there is a way to avoid alarm trigger when there is a lack of signal? Almost everyday my alarms are triggered and I don't know way there is this lack of signal for some sec/minutes:

Interesting, I didn't realize that "--" might give a true when compared with a number. However, simply replace "--" in your definition by another default value that does not hit the trigger. For the clear condition "0" might do the trick, in rise condition "9999" should be fine.
