[RELEASE] Official Monoprice Plugin Power Monitor Device Handler

RBoy Apps is now an official partner of Monoprice.

This Device Handler is for the Monoprice Plug In Power Monitor (15903).


This Plug In Power Monitor can be operated remotely or directly, using the Switch on the device. It plugs into a standard NEMA 5-15 power outlet and includes both a Z-Wave controlled outlet and standard, unswitched outlet. It is designed so that when it is plugged into a standard two-plug wall outlet, it will not block the other power socket. In addition to controlled switching, it monitors energy consumption and can report consumption values in several common energy scales. As an AC powered Z-Wave device, this Plugin will act as a Z-Wave repeater (supporting FLiRS).

This device handler supports the Z-Wave and Z-Wave Plus devices. Support has also been added for v1 and v2 hub fingerprinting for easy identification. Ideally install the Device Handler BEFORE pairing the device for easy setup.

Cab this handler be used to send notifications? Looking for washing machine status notifications. Thanks.

Only SmartApps can send notifications, device handler can report events to SmartApps. What you can do is use a SmartApp like CoRE or WebCoRE and create a rule to notify you when the device handler sends an event that’s above or below a threshold (like power consumption or amps etc)

  • Support for new ST app custom controls

NOTE: It may have 48 hours for the platform cache to update the UI, it helps to switch the DTH, sign out of the ST mobile app and then sign back in to force a refresh. As last resort, you may need to exclude your device, delete the device handler and re install it for the changes to take effect.
