Check if current time is between two times

[Edward Trapp 0]

Hi

 

I'd like to share very handy function to check if time is between two other times. This is very useful for example for checking if motion sensor should at this time of day switch warm or cool lights. There are two functions

IsTimeBetween(StartH, StartM, StopH, StopM, TestH, TestM) - which checks if TestH:TestM is between StartH:StartM and StopH:StopM

IsItBetween(StartH,StartM,StopH,StopM) - this one is a wrapper to check against current time of day.

local debug = false

local function IsTimeBetween(StartH, StartM, StopH, StopM, TestH, TestM)
  -- Convert all times to minutes for easier comparison
      local TempStart = StartH*60+StartM
      local TempStop = StopH*60+StopM
      local TempTest = TestH*60+TestM
  -- Debug
      if (debug) then
        fibaro:debug("TempStart: " .. TempStart)
        fibaro:debug("TempStop: " .. TempStop)
        fibaro:debug("TempTest: " .. TempTest)
      end
  -- Check for possibility that end time is on next day
  -- (when ending time is before start time)
      if (TempStop<TempStart) then
  -- If it is check if tested time is on next day as well
  -- (when tested time is after midnight but before ending time)
        if (TempTest<=TempStop) then TempTest = TempTest + 24*60 end
        TempStop = TempStop + 24*60
  -- Debug - display times after adjustments
        if (debug) then
            fibaro:debug("- After adjusting times -")
            fibaro:debug("TempStart: " .. TempStart)
            fibaro:debug("TempStop: " .. TempStop)
            fibaro:debug("TempTest: " .. TempTest)
        end
    end
  
  -- Debug
      if (TempStop<TempStart) then
        fibaro:debug("IsTimeBetween() - Invalid parameters!")
        fibaro:abort()
    end
  -- Return
       return (TempStart <= TempTest and TempStop >= TempTest)
end

local function IsItBetween(StartH,StartM,StopH,StopM)
 -- Simple wrapper to check current time
    local time = os.date("*t")
      return IsTimeBetween(StartH, StartM, StopH, StopM, time.hour, time.min)
end

 

 

 

 

 

Example of usage with RGBW controller and Motion sensor:

 

Quote

 

--[[
%% properties
666 value
%% weather
%% events
%% globals
--]]

 

 

******** Paste functions here *************

 

-- Actors' IDs
local MotionSensor_ID = 666

local RGBW_ID = 999

 

-- Define range of time - in this example I want to turn different light settings on my RGBW led stripe at different times of day - Full Light during evening and subtle warm light at night

local EveningStartHour = 20

local EveningStartMinute = 00

local NightStartHour = 23

local NightStartMinute = 00

local StopHour = 05

local StopMinute = 00

 

-- Check if its evening

if (IsItBetween(EveningStartHour, EveningStartMinute, NightStartHour , NightStartMinute)) then

        fibaro:call(RGBW_ID, "setColor", "255","255","255","255")

        fibaro:call(RGBW_ID, "turnOn")

-- Check if its night

elseif (IsItBetween(NightStartHour , NightStartMinute, StopHour, StopMinute)) then
        fibaro:call(RGBW_ID, "setColor", "15","7","0","0")

        fibaro:call(RGBW_ID, "turnOn")

end

 

 

 

This solution isn't idiot proof so if You put absurd hours You will get absurdal behaviour. It isn't also proof to daylight savings time. Otherwise it works just fine. Function like this should come as a standard in Fibaro API. Hope someday it will.

 

 

@Admin - for some reason I couldn't start new topic in crowds solutions so I've put it here.

Here is a version that handles sunset/sunrise, +/- offsets, and fibaro globals. 'toTime' that converts an expression to seconds, and a similar 'between' as in your example above.

small error in regexp

timeNow                     = os.date("%H:%M")
local EveningStart     = "20:00"
local NightStart         = "23:00"
local StopHour          = "05:00"
if timeNow > EveningStart and timeNow < NightStart then
  fibaro:call(RGBW_ID, "setColor", "255","255","255","255")
  fibaro:call(RGBW_ID, "turnOn")
elseif timeNow > NightStart and timeNow < StopHour then
  fibaro:call(RGBW_ID, "setColor", "15","7","0","0")
  fibaro:call(RGBW_ID, "turnOn")
end

Hello Kage,

Nice  LUA was looking for it!

Is it possible to change local evening start with fa sunset minus 45 minutes?

If I do it I will get errors

fa if I change "23:00">>>>"fibaro:getGlobalValue("DayEveningNight") == "Night" " will give error >>

Kage, thanks for simplified time comparison code - didn't know with LUA it's that simple. Still Your code needs tweaking because its not 2-days-span proof - mathematiclly 01:00 is never > 23:00. I'll rewrite my function with Your method later.

 

As for Sjakie You might be looking for: fibaro:getValue(1, "sunsetHour") but for now i can't tell You how to easily modify it by 45 minutes

It's going to take some time to understand all those brilliant shortcuts but that's as short and sweet as it could be. Thank You @jgab

It's small because there are no error checks - expects valid expressions or will produce strange results.

Yep...

Is that lua equivalent of (a>=b  ?  x : y)   ?

Yes, lua lacks that construct so a common pattern is:  a = <test> and <va1> or <val2>

which then becomes a bit smaller than an if-then-else.

However, it’s not equivalent, as <val1> can’t be false or nil...

@sjakie 

change local EveningStart  = os.date("%H:%M", os.time()+45*60)

[Sjakie 145]

Great, thanks
