TESTIMONIALS

How ER316W works in everyday installations.

Three users describe how independent three-output control simplified their setup.

01
I use it to control the lighting, water heater and outdoor socket separately. I can now manage everything from my phone without needing three separate relays.
Dimitris · HomeownerThree circuits, one device
02
At the holiday home, I wanted to switch on the outdoor lights before arriving. With ER316W I control all the exterior lighting from the same app and need fewer devices in the panel.
Anna · Holiday-home ownerRemote exterior-lighting control
03
I use it for the lighting, water heater and outdoor lighting at my Airbnb. I can control them separately from my phone and schedule their operation.
