Hi @david24. I also have lots of Oomi (Aeotec) devices. For the door/window sensors I use the Aeon Recessed door sensor driver here: Aeon Recessed Door sensor
For my Multisensors I use cSteele's driver here: Another Aeon Multisensor 6 DH
It can also be downloaded through Hubitat Package Manager (HIGHLY recommended): [BETA] Hubitat Package Manager
Before anything use the Z-Wave parameter tool as suggested by @Mr.Olsen and make sure all your devices have a 0 in paramter 252. By default they came set to 1.
Let us know how it works out.
