I agree. The Yatse app is one of the most useful tools for me combined with my Kodi instances.
For integrating this enhancement to the OH2 binding you have to think about how the results can be mapped to the channel concept of the OH2 framework. I suppose returning a list of data using a channel is a not supported feature. Maybe there is a way to retrieve the data with the HTTP binding and use a transformation like JSONPATH to extract the info you need.
Spent ages trying to get this workng but was having huge issue with http bind/json due to encoding. For some reason api needs to have quotes in the string but even with it encoded it didn’t work.
I ended up creating a python script to do the job. Working perfectly in OH2
Feel free to use the code. I"m not a developer so its not the prettiest code and might have some horribly bugs, but it gets the job done.
