Updated the Battery Command Class to V2.
Both values of the Binary Switch/Basic Set are now accepted if the actuator is manually stopped in the middle of an open/close cycle.

Firmware: 1.21

Fixed the issue of BATTERY_GET returning V1 instead of V2
Support the Battery Command Class V2 regardless of whether battery backup has been plugged in or not

Firmware: 1.24

Fixed the auto-close function when a low battery alert is triggered and the backup battery is connected and charging. The valve will not auto-close anymore.

Hardware: 4

700 Series Z-Wave chip
The metal casted transmission fork was changed to the new high-quality plastic (UV proof acetal homopolymer) transmission fork. This new-generation plastic transmission fork can fit lower-profile valves and will not damage the metal valve lever over time.

Firmware: 2.00

Firmware: 2.10 (released 09/2024)

Fixed a bug: Temperature reporting frequency is now reporting correctly in minute intervals set in parameter 45.
