  • The hour and minutes are strings convert to numbers e.g. 7 < tonumber(hour) to compare to other numbers

  • As the Sunset and Sunrise is a string it is hard to compare to the current time to check if it is day or night.

    This is a workaround:

    Create a variable nightTime

    Create a scene with

    NOTE the variable is only set as the time passes sunset and sunrise values so it must start at the correct value.

    Use the variable in other scenes if nightime == "1" then turn my light on when movement... etc

    You can adjust night by adding minutes to sunset or removing from sunrise.

    This is very useful, Rob. Thanks for posting.

    I'm just getting started with LUA. I used to do programming (long time ago though) so understand that part. I'm searching for a simple list of functions available in fibaro (eg figaro:debug(). Would you have anything like that?

    In particular, I am now looking for the function to write logging data to the Event log. Any clue what that is?

    Thanks!

  • For the built in this is the only doc I am aware of. There is a post saying English version is WIP:

    Please login or register to see this link.

    for other things I am learning by trial and error: For basic actions and properties of devices try by building a block script and converting.

    For some devices I could not see anything I wanted, so I went looking for hints: look in new_properties and new_actions tables. Some of these are exposed not sure how many or how many we can rely to stay. They are undocumented features. There are some interesting ones.

    For what you are asking the only way I can think of is a direct database insert but I would not do that myself. Could interfere with the operation of the system.

    Hi Rob and Jompa,

    I see you're both having nice scripts finding a way to make a proper sunrise and sunset timer. How do you guys implement this?

    Do I need to make a variable or predefined variable in the "variables panel" for this to work?

    So I need to declare a %%global at the start of the script to get this working?

    I'm fiddling with it, to use this nightTime or Night variable in my frontdoor sensor script to only trigger the hallway lighting during night time

    I'll won't clutter this thread by posting my code snippet in here, but having a general feel on how to work with the variables would be nice to know and it would make it easier to implement this.

    Hi

    yes create a variable for this in variable panel. Here is my scene code

    Jompa, a standard variable or a predefined variable with a 0 and 1 as value options?

    Reason for asking is I've created a standard variable named Night (yes, I've adjusted NightTime to Night) and had it set at value 0.

    I might interpret the code wrong, but will it only switch to Night when the actual time passes, or is it doing this at "any time" during sunset hour?

    Small code for testing if there are any DEAD devices and inform you by email. You can add a code to run it i.ex. every hour.

    --[[

    %% properties

    %% globals

    --]]

    local i = 1

    local TotalDevices = 156 + 1

    while i < TotalDevices do

    local status = fibaro:getValue(i, 'dead');

    if status == "1" then

    fibaro:debug("Device "..i.." DEAD");

    fibaro:call(2, "sendEmail", "DEAD "..i);

    else end

    i = i + 1

    end

    Folks, since my update to 3.488, the Sunrise/sunset values seem off. I got home this afternoon at 5pm and all my lights were on. Right now, my system thinks Sunrise is at 7:48 (should be 7:12) and sunset is at 15:42 (should be 18:29).

    I did check my GPS location - it is correctly set to Almere, Netherlands.

    Anyone else experiencing this?

    Here a small sleep function

    Now everywhere in your script you just use

    sleep(value)

    Hi all. I gave it a shot into the Lua world today. Intention is to learn on the fly a bit and this will hopefully help me to understand the wiki's around all this later. For now I'm struggling….

    This is wat I did. I reviewed the code of an existing (converted) scene and stole some code from mr Jompa68 (Thanks!).. The new code works fine (as it seems) and should allow me to have a universal Sunset Scene that can be offset and listens to day of the week.

    Please login or register to see this code.

    Now..my questions are:

    1. When you create a new scene you have the option to select “Start when Homecenter 2 Starts”. Once past this page, you cannot change this setting anymore. Is this correct and if so why is this?

    2. I assume this setting tells the system to start this script as part of the power up. Correct?

    3. To ‘unhide’ this setting my thinking is to use fibaro:getSourceTrigger() and test for “autostart”. But what will this do then, after all, the scene may not activated after a powerup etc ??

    4. The ; at the end of statements, when and why are they needed?

    Grateful for any answers!!!

    Regards,

    Hans

    1) if you are in LUA, you can control this by having %% autostart or not. If you do not want the scene to autostart remove that from the code. Checkbox is not necessary.

    2) yes

    3) not sure what your question is but I only use this test if I want the scene to behave differently depending on how the seen is activated. It is not compulsory to use it.

    4) optional- use it if you like it and think it is more readable

    Thanks robmac. Pretty clear now. One final question: the LUA code typically starts with lines such as:

    Please login or register to see this code.

    All these lines a 'greyed-out' as they are between --[[ and ]]-- Are these statements still active then?
