Cannot get all buienradar data from json call
Posted: Sunday 17 December 2023 23:54
My home is inbetween Groenlo and Twente.
To get a more or less accurate local temperature I'm polling buienradar.
Stations with a number 29 or less can get retrieved with a json call.
Twente however is numer 30 and buienradar refuses to send data ( the json call is not successfull)
Here is my script.
At station 30 the log reports:
