Light on at different dim level depending on daytime, with auto off [SOLVED]

[cogliostrio]

Thought Id share a script I made for turning on a light at different dim levels, depending on the time of day.
Hopefully it can be useful for others as well. Id also be interested to know if there are better ways to write something like this.

Code: Select all

return {
	on = {
		devices = {'PIR'}, -- Change out PIR
	},
   execute = function(domoticz, PIR)
   local Light = domoticz.devices('Light') -- Change out light

        if (PIR.state == 'On') and (domoticz.time.matchesRule('at 00:01-08:00')) then
            Light.dimTo(2)
            domoticz.log('DzVents: Light 2%, 00:00-08:00')

        elseif (PIR.state == 'On') and (domoticz.time.matchesRule('at 08:01-12:00')) then
            Light.dimTo(20)
            domoticz.log('DzVents: Light 20%, 08:00-12:00')

        elseif (PIR.state == 'On') and (domoticz.time.matchesRule('at 12:01-23:00')) then
            Light.dimTo(100)
            domoticz.log('DzVents: Light 100%, 12:00-23:00')
         
        elseif (PIR.state == 'On') and (domoticz.time.matchesRule('at 23:01-24:00')) then
            Light.dimTo(30)
            domoticz.log('DzVents: Light 30%, 23:00-24:00')
         
        else
            Light.switchOff().afterMin(1)
            domoticz.log('DzVents: Light off')
        end
    end
}

Thx for sharing. As long as the script does where it is designed for, 'better' is subjective. The example below could be seen as easier to maintain and/or extend but it is still a matter of personal preference how you like your code to look like.

Code: Select all

return {
	on = {
		devices = {'PIR'}, -- Change out PIR
	},
   
   execute = function(dz, PIR)
        local Light = dz.devices('Light') -- Change out light
   
        local dimTimeTable  = { --  [   'timeSlot'   ]  = dimValue
                                    ['at 00:01-08:00']  = 2,
                                    ['at 08:01-12:00']  = 20,
                                    ['at 12:01-23:00']  = 100,
                                    ['at 23:01-24:00']  = 30,
                              }
                              
        if PIR.state ~= 'On' then 
            Light.switchOff().afterMin(1)
            dz.log(Light.name .. ' switched Off')
        else
            for timeSlot, dimValue in pairs (dimTimeTable) do
               if dz.time.matchesRule(timeSlot) then 
                    Light.dimTo(dimValue)
                    dz.log(Light.name .. ' switched On (dimlevel: ' .. dimValue .. ')')
                    return false
               end      
            end

Hi Waaren. How would this script look like when you want to do this depending on lux level ranges from a lux device within time slots

[waaren]

Can you give some examples on what mean ?
something like if between 08:00-12:00 and lux between 100-500 then dimLevel 30 ?

Yes, exactly that. I have groups, possible to dim them as a group? Or I can just make scenes and trigger them instead of dim level?

Dim as a group to a variable dimLevel is not natively possible in domoticz but with dzVents you can loop over devices in a group to do this

Thanks waaren. Managed to test it. It seems to work, but a few things I noticed:

• Using the following time slots:

  Code: Select all

          local dimTimeTable  = { --  [   'timeSlot'   ]  = { [measuredLux]   = dimLevel 
                                      ['at 00:01-15:00']  = { 
                                                                  [2]       = 70,
                                                                  [3]       = 70,
                                                                  [4]       = 70,
                                                                  [5]       = 70,
                                                                  [6]       = 80,
                                                                  [7]       = 80,																										 
                                                                  [8]       = 80,
                                                                  [9]       = 80,
                                                                  [10]       = 80,
                                                                  [12]       = 90,
                                                                  [15]       = 90,
                                                             },
  

  
  
  it still switches the lights on to 90% at a lux level of 73 at the moment.

• I have a dummy on/off switch which groups 4 spots. The dummy switch is also in the group which I use in your script. When your script kicks in it switches this dummy switch to off. Where it should switch it to on.

• How does your script handle the lux levels exactly? What if I want to match a range of lux level to the same dim level? Like the 0-5 lux range to dim level 70 and 6-10 to 80?

• Is it possible to embed a threshold to switch off the lights above a certain lux level? Or does it work like that already? I didn't notice that maybe?

Thanks again. Already helped me a lot.

Correct. The script picks the percentages from the lux level that is closest. If you want to a different percentage above a certain level you should add that combination. eg if you want a dimlevel percentage of 0 when lux >= 50 you should add something like
[49] = 90,
[50] = 0,
to the dimTimeTable

• I have a dummy on/off switch which groups 4 spots. The dummy switch is also in the group which I use in your script. When your script kicks in it switches this dummy switch to off. Where it should switch it to on.

The script is not designed for an on/off switch. It is designed and tested for dimmable devices.

• How does your script handle the lux levels exactly? What if I want to match a range of lux level to the same dim level? Like the 0-5 lux range to dim level 70 and 6-10 to 80?

set dimTimeTable to
local dimTimeTable = { -- [ 'timeSlot' ] = { [measuredLux] = dimLevel
['at 00:01-15:00'] = {
[5] = 70, -- lux 0-5 will set dim% to 70
[6] = 80, -- lux 6-10 will set dim% to 80
[10] = 80, --
[11] = othervalue, -- lux 11 and above wil set dim% to othervalue

• Is it possible to embed a threshold to switch off the lights above a certain lux level? Or does it work like that already? I didn't notice that maybe?

set dimTimeTable to
local dimTimeTable = { -- [ 'timeSlot' ] = { [measuredLux] = dimLevel
['at 00:01-15:00'] = {
[5] = 70,
[6] = 80,
[11] = 0,

Thanks waaren. Working perfectly now.

Hi, this is exactly why I started using Domoticz in the first place So good job!

However, I'm a huge n00b in this area and I need a little guidance, since I don't get the script to work. My question is: do I need to create something in order to make this work? For instance a dummy switch, groups, anything?

Or, mayby I don't understand the working of the script As I understand it: lights are turned off, then when I switch them on, they flip on at a certain dim level, depending on the time. Correct?

Hope you can help!

[waaren]

Or, maybe I don't understand the working of the script As I understand it: lights are turned off, then when I switch them on, they flip on at a certain dim level, depending on the time. Correct?

The script is triggered by a motion sensor and set a dimmable light to a certain dim level based on a combination of measured Lux and time of day. So to get it working, you need a Lux measuring device (real or virtual), - a motion sensor (can also be a switch) and a dimmable light.

What device do you use for the PIR? I mean, what hardware?

[waaren]

What device do you use for the PIR? I mean, what hardware?

I use three different types. I started with a KlikAan KlikUit (RFtrx433 /RFLink). Then I tried a Fibaro type (zwave) and now I use Xiaomi Mijia IR Intelligent Human Body Sensors.
They all do the job so that's why, for now, I stick to the last one (cheapest)

[jaaap]

Great, then I'll order a couple of those, with the gateway of course

[botany]

is it possible to change dim level manual ?
and if there is movement. lights stay on same level as i put it manually?
because sometimes its nice to change the dim level depending on the situation .

Yes that is possible. My approach would be to use a virtual dimmer as override that sets the dimlevel of the devices in the group to the same level as the virtual dimmer and use that same virtual dimmer as override if it is not 'Off' or has dimlevel 0.

Something like

Code: Select all

return 
{
    on = 
    {
        devices = 
        {
            'PIR',
            'virtualDimmer',
        }, 
    },
    
    logging =   
    {   
        level = domoticz.LOG_DEBUG,  -- set to error when script is tested and OK
        marker = conditionalDimmer,
    },

    execute = function(dz, item)
        local Lux           = dz.devices('Lux')

thanks.
will try it out tonight.

I'm coming from Fibaro. trying to get out of the close system of them.
was only possible to use (expensive) zwave module/hardware.

i used a scene with fibaro made by Sankotronic.

Spoiler: show

very smart light- https://forum.fibaro.com/topic/28726-ve ... hts-scene/

now im looking for same scene like his.

so i can switch to Domoticz. this was the only scene is used with Fibaro. others where on and off and time based.

Not only the system is closed; also the forum I am not allowed to view the topic without a user-id...
