I have a released a generic driver for the Philio PAT02-A/B/C Flood / Temperature / Humidity sensors. It works with both the secure and non-secure versions of the device. This driver was derived from the original PAT02-B driver found here, and is intended to replace that driver over time.
I wish to extend my thanks to @kunpet, who was kind enough to perform several rounds of testing with his PAT02-A to help produce this driver.
Code can be found here: GitHub - dennypage/hubitat: Hubitat drivers and applications
Thanks,
Denny
