api calls without internet connection hang my script

[Theo 7]

Hi all,

 

On my HC2 I have been running a single LUA-script (with calls to helper scripts) to manage the whole house. For energy consumption reduction I switch off devices when not needed. Therefore also my internet modem is switched off during night hours.

For several years this never gave problems until recently.

The script stopped a few minutes after modem shutdown:

To my surprise the failing call had (as far as I understand) nothing to do with the internet:

The global variable is a json array and exists. This array may be changed by another script, therefore I check this regularly. Why is it failing now after more than a year of uninterrupted use? And where is the dependency on an internet connection?

Also a call to the weather information did not hang the script during years without nightly internet. And now suddenly it did in a similar way as above.

Can someone shed a light on this change in behavior?

 

thanks in advance
