So.. I am super stuck (on probably the last step).
I have Teslamate running just fine on a Synology Docker with the
teslamate-mqtt-api running as well.
I can successfully access the data on the teslamate-mqtt-api by going to http://192.168..xxx.xx7:3040/car/1?api_key=1234xxxx
I downloaded the scriptable widget and the Tesla data folder and moved the items to my iCloud scriptable folder so that TeslaDataWidget is in the main folder and Tesla_data is a subfolder.
I hardcoded the API URL above using in the parameters.js file (inside Tesla_Data).
When I try to run the script or use the script as a widget, I receive the error 'Error on line 420:29: Expected value of type string but got value of type number.
I am at my wits end and any help would be greatly appreciated.
