The main problem is this one introduced in 2/5 which needs get ack from maintainer. For me, I would suggest to make sensor_specs transparent to user if it's really not needed by users. Please try to make it either optional or hide to core users as well. And I guess the later one is doable after a glance at the core code. Regards Dong Aisheng
