This is great stuff! I was having this issue with an Aeotec by Aeon Labs ZW097 Dry Contact Sensor on Hass.io. I went into Configuration > Z-Wave and then chose my node, went down to Node Config Options. There I picked Report Type in Config Parameters and then chose Sensor Binary Report from the list. When I went to Set Config Parameter I made sure to hit the trigger button on my sensor a few times to wake it up. After that all is well! Works like a champ!
Thanks again for all the info!
