Since there is another HomeAssistant app available for the Toon (https://www.domoticaforum.eu/viewtopic.php?f=87&t=12089), which has dynamic objects so you can add virtually unlimited switches etc.
My suggestion, just like marcelr's and Luc_S' is to combine forces and greate a good stable app.
Which layout do you preffer if I may ask?
The one of this thread or the one posted in the link above?
