VER. 1.03

Firmware: 1.03

VER. 2.0 (released 06/2023)

Hardware:

• 700 Series Z-Wave chip for extra range and reliable communication

Firmware: 2.00

• Added 7 input types to choose from to monitor separately from the output control. See all advanced parameters here.

Firmware: 2.10 (released 05/2024)
