TESTIMONIALS
How ER516W works in everyday installations.
Three users describe how multi-circuit 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 ER516W 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.
