Frequently Asked Questions - WSEPM21 SANUS
How do I install the Sanus WSEPM21 energy monitor?
To install the WSEPM21, first turn off power to your electrical panel at the main breaker. Then attach the included clip-on sensor around the main power feed wire, and connect the device to the supplied power source. Finally, download the Sanus Home app and follow the in-app instructions to complete the Wi-Fi setup.
Can the WSEPM21 work with smart assistants like Alexa or Google Home?
Yes, the WSEPM21 is compatible with Amazon Alexa and Google Assistant. After pairing it with the Sanus Home app, you can enable the appropriate skill/action to view energy usage via voice commands.
What is the measurement accuracy of this device?
The WSEPM21 has a typical accuracy of ±1% for current measurements in the range of 5A to 100A. This is sufficient for most residential energy monitoring needs.
How do I reset the WSEPM21 to factory defaults?
To reset the WSEPM21, press and hold the reset button on the side of the device for 10 seconds until the LED flashes red. Release the button; the device will reboot and you will need to reconfigure it via the Sanus Home app.
Is the WSEPM21 safe to use in an electrical panel?
Yes, the WSEPM21 is designed for safe installation inside the electrical panel. It is certified to CE and FCC standards and uses a non-invasive clamp sensor that does not make direct electrical contact with live wires. However, installation should only be performed by a qualified person with the main power turned off.
Can I monitor multiple circuits with one WSEPM21?
The WSEPM21 comes with two included clamp sensors (one for each phase in a split-phase system) and can measure the total household consumption. For individual circuits, you would need additional units or a more advanced monitoring system.
How does the WSEPM21 connect to my Wi-Fi network?
The WSEPM21 connects to a 2.4 GHz Wi-Fi network (802.11 b/g/n). During setup, the Sanus Home app detects the device via Bluetooth and configures the Wi-Fi credentials automatically. Ensure your router is broadcasting its 2.4 GHz SSID.
What happens if the power goes out?
If a power outage occurs, the WSEPM21 will automatically reconnect to your Wi-Fi network when power is restored. It retains its configuration and historical data in non-volatile memory, so you won't lose your usage history.
How do I clean and maintain the device?
For cleaning, use a soft, dry cloth to wipe the exterior. Do not use water, cleaning sprays, or solvents, as they may damage the device. There are no user-serviceable parts inside; disconnect power before any inspection.
Does the WSEPM21 support data export or integration with other systems?
Yes, the WSEPM21 allows data export via the Sanus Home app (CSV format) and has an open API for integration with home automation platforms like Home Assistant and Node-RED. Check the app's settings for API access tokens.
