You should use “ResRobot - Reseplanerare" and create a API for that service instead of “platsuppslag”.
i get ID: 740024784 and name “Lidingö Rudboda torg” when i search for Rudboda torg
It looks like the Station ID is wrong. My “From station ID” for “Gubbängen” is 740021699.
You can create a API for “ResRobot - Reseplanerare” and then type in this URL in the browser: https://api.resrobot.se/v2/location.name?key=YOURE API KEY&input=SEARCH WORD
Replace the bold parts, whit API-key and search word for exampel T-centralen
You will get a XML response with all the possible results and the differnet ID (Stations ID)
And then make sure you use the service “ResRobot - Stolptidtabeller 2” in the config.
