Took a chance on this for my garage door and the roller shutter mode works flawlessly right out of the box. The power metering in the app is surprisingly precise—I can see exactly what the motor draws each cycle. Solid little board, and the UL stamp gives me peace of mind near the breaker panel.
The dual-channel setup let me wire both my garage light and a fan on one unit, and the power metering in the app is surprisingly accurate. Install took maybe twenty minutes, and the Wi-Fi connected without any drama on my router.
Used it for roller shutter control and the built-in power metering is a nice bonus for tracking usage. Took maybe fifteen minutes to wire it in, and the Wi-Fi response has been instant every time. UL certification gave me peace of mind for the install.
