Problems with Darksky script

Steef · Post by **Steef** » Monday 07 January 2019 11:49

Hello Domoticz fanatics,

My name is Steef, and I am exploring the (endless) possibilities of the Domoticz workaround.
I have Domoticz running on a Raspberry Pi 3b, running on Raspbian.

Because I would really like to receive detailed weather information, I am trying to follow a nice how-to I found on the internet: https://ehoco.nl/domoticz-weerstation/ (The how-to is in Dutch).

I followed the how-to, but somehow, I receive an error on the following line:

Code: Select all

commandArray[#commandArray+1] = {['UpdateDevice'] = otherdevices_idx[device]..'|'..tostring(nvalue)..'|'..tostring(svalues)}

The error I receive is: Error: EventSystem: in Darksky weerstation: [string ” –[[ WEERSTATIONS: …”]:36: attempt to concatenate field ‘?’ (a nil value)

The complete script is mentioned below. I am trying to understand the .lua language, but it is new to me, and can not find the error.
Is there anyone who can help me with this problem? many thanks!

I have exactly the same error.
Did you find a solution?

Thanks for pointing me to this script will give it a try next week....

Just a quick reply on the errors you see :
The error says one of the strings in line 36 is empty. Empty value is not possible after .. in lua
You could use the print() command in lua to write something to the log.
like :
print(device)
print(nvalue)
print(svalues)

place it before the error and look in the log when it is executed.
it will give you a clue about what is going on

Do not forget to insert you domoIP !
You also need to have the dummy sensors in place with idx mentioned in the local dev_ section just above...

Thank you "zicht" for your reply.
I solved the problem already.
My solution was found in in the handling of the sensor "Groundtemperature".
The device for the sensor had the discription: "Temperatuur grond", while the script was refering to "Temperature Ground".

Thank you again.

Regards,
Wallgarden
