how to do action once in period of time

[dorzel]

hello i have a problem with this event.
this is what i try to achieve.

when I turn off the lights in woonkamer in the evening between 22:30 and 1:00 o'clock
I want the lights to turn on in the slaapkamer for 20 minutes.

The problem is that once the 10 minutes are past, the lights in slaapkamer turn off and turn on again for 10 minutes in a loop till 1:00 o'clock
help would be appreciated.

Hello dorzel,

I am suprised that the blockly does something at all. In my opinion there is a problem with the time statements. When it's 00:30h, it's not after 22:30h. The day ends after 23:59h and a new one starts at 00:00h.
But then there is this: time changes every minute. So when the lights in woonkamer are off and time is changing every minute, then every minute the statement would be true. Then when the lights in slaapkamer turn off after 10 minutes (you say you want it to be on for 20 minutes, but in blockly you put 10?), then a minute later it will turn on the light again as the condition is still true. So it will turn on the light in slaapkamer again.

When I want something only to happen once during a certain period of time, I use a variable. I set it default to 0. In the blockly I check the value of the variable and when it is 0, I let the blocky change it to 1. Then next time it checks the variable, it's not 0 anymore so it won't act. If the period of time ends at 01:00h, I would make another blockly that states: If time = 01:00 then set variable = 0.

hi mrf68,

i mistaked the 20 minutes, and as the blocky shows it should be 10 minutes,.
you made a lot clear, this weekend i will try to make an new evend in blocky like you described.

thanks for your answer.

Otherwise, use a simple lua script.

Assuming I have read your descriptiong correctly then, this untested Lua code would do what you want, you need to create a dummy switch called 'goneupstairs' which is set to 'Off' and has timer set to turn it 'Off' at 2:00 every day.

You need to either use the built in script editor choose, Lua, device and enable, or place this script in your Lua script directory.

Basically just a series of if statements, detect the switch being turned off, check its not a Sunday, check time is between 22:30 and 1.30, check goneupstairs is 'Off' only if all true then switch slaapkamer on for 20 minutes and turn goneupstairs 'On', so it won't happen again.

Code: Select all

-- /domoticz/scripts/lua/script_device_onceanight.lua
commandArray = {}

--  Only react when woonkamer is turned off
if (devicechanged['woonkamer'] == 'Off') then
   -- Get time
   time = os.date("*t")
   -- Caculate current time in minutes
   dayminutes = time.min + time.hour * 60
   dm2230 = 30 + 22 * 60
   -- Only react when time is between 22:30 and 1.30
   if (dayminutes > dm2230) or (dayminutes < 90) then
      wday = time.wday
      -- Account for 00:00 - 01:30 on Sunday should be treated as Saturday night, not Sunday night
      if (dayminutes < 90) then
          if wday == 1 then
               wday = 7
          elseif wday = 2 then
               wday = 1
          end
      end
      -- Only react when it isn't a Sunday (wday = 1 on Sunday)
      if wday > 1 then
         -- Only react if goneupstairs is off
         if (goneupstairs == 'Off') then
            commandArray['slaapkamer'] = 'On FOR 20'
            commandArray['goneupstairs'] = 'On'
            print('Once a night')
            print(time.year..' '..time.month..' '..time.day..' '..time.hour..' '..time.min)
         end
      end
   end
end

return commandArray

Your Blockly is going in the right direction, accepting comments above, and not possible to both greater than22 and less than 1, but I am not quite sure the logic would be as you expected as the way you have grouped things with ands, it is very difficult to see with Blockly which conditions will occur together, the code above separating out different concepts, days, minutes and switches would be easier to debug.

hello simonrg,

I'm fairly new to domoticz and I admire people who can write scripts.
I also understand that blockly has its limitations.
your script example will help me to understand this Lua script.
So my next project will be to learn writing scripts.

I will definitely try this script.
Thanks for your help.
