Reading lux sensor

[pkelderman]

Does somebody know how to retrieve the number of lumen/lux from a lux sensor? Thanks at forehand! I want to use it in a lua-script.....

[Toulon7559]

Which type/model of lux-sensor?

[madpatrick]

In Dzvents it is like this

Code: Select all

execute = function(dz)
local lux           = dz.devices(454).lux
if lux = 100 then .....

454 is of course your device number

I'm using a ZW100 Multisensor 6+ from Aeon Labs; the same brand as my controller, that's a ZW090 Z-stick Gen5 from Aeon labs. Need more info? Please tell me?

[pkelderman]

I tried;
current = otherdevices_humidity[TempEnVocht]
current = devices(Lichtsterkte)

the first one works, the second gives:

2022-09-12 19:09:00.140 Error: EventSystem: in /home/pi/domoticz/scripts/lua/script_time_PIRs.lua: /home/pi/domoticz/scripts/lua/script_time_PIRs.lua:29: attempt to call a nil value (global 'devices')

I tried;
current = otherdevices_humidity[TempEnVocht]
current = devices(Lichtsterkte)

the first one works, the second gives:

You need to add .lux after device name

Code: Select all

 current = devices(Lichtsterkte).lux

[pkelderman]

I have tried:
local Lichtsterkte = 'Lichtsterkte'
current = devices(Lichtsterkte).lux
print(current)

The log says:
2022-09-13 14:35:00.160 Error: EventSystem: in /home/pi/domoticz/scripts/lua/script_time_PIRs.lua: /home/pi/domoticz/scripts/lua/script_time_PIRs.lua:34: attempt to call a nil value (global 'devices')

I have tried:
local Lichtsterkte = 'Lichtsterkte'
current = devices(Lichtsterkte).lux
print(current)

Can you post the complete script.
I'm aan NoNo on Lua and little bit better in Dvents, but maybe i can assist in getting you in the right direction

Try:

current = tonumber(otherdevices['Lichtsterkte'])

Then don't use:
if current==100 then

But use f.i.
if current >90 and current <110 then

Chances are the value of 100 is skipped due to the refresh interval.

I tried;
current = otherdevices_humidity[TempEnVocht]
current = devices(Lichtsterkte)

the first one works, the second gives:

You need to add .lux after device name

Code: Select all

 current = devices(Lichtsterkte).lux

And "dz.devices" instead of just "devices"

And "dz.devices" instead of just "devices"

Think this is a regular LUA time script looking at the script path, so otherdevices is the arrayname to use!

@ asonneveld

I tried next solution:

current = tonumber(otherdevices['Lichtsterkte'])
print(current)

the result:

39

Wow it works! Thanks a lot!
