First stable version + UI is ready.
It’s works like original app, with correct malfunctions and arm errors processing.
It uses modified Jeedom Ajax Plugin as proxy to original AJAX API.
I use official Ajax API documentation (it’s open to public) and skip all jeedom ajax plugin processing. It’s only limited to Ajax API.
There is readme in repo how to install and configure my integration.
The integration was build with HA UI in mind, so some sensors optimized to use in UI as easy as possible.
