Probably a bit of an unusual approach: I'm storing the status of Tado's home/away sensing (which uses great geofencing for multiple family members) to store a variable in ImSmart (AwayModeOn as a boolean) using TADO to set the value through a WebHook.
I want to retrieve this value so that I can use it in filters for my wider IFTTT flows that will be controlling my Lightwave lighting (currently trying this with IFTTT Pro for multiple steps) but tests using a WebHook in IFTTT to retrieve the value does not seem to be working!
The WebHook call
https://www.imsmart.tech/API/Values/<GUID>/GetValue/ works fine from a browser but only returns the call status (200) and blanks when used from IFTTT (using GET). I have tried all the formats specifically supported in the WebHook IFTTT connector - application/json, application/www-x-form-urlencoded and text/plain.
I'm probably doing something stupid (or something that is not currently supported) so I would appreciate any pointers on how to get this working.
