Installation of a Deta smart 4 gang switch Grid Connect

I had purchased a 4 gang smart switch off Ebay and it failed after a few months. This switch as a 12 month warranty so i'm going to keep the packaging and the receipt. Bought today from Bunnings in Morwell, Vic.
I basically did a straight swap over. Not so easy to touch the screws that maybe live if you're not paying attention, the screws are also more substantial than the cheap one I bought off the net.
My tag in the video says Delta but this should read DETA.

Did you have neutral wire? And can you elaborate on the relays?

[@mikeycbd]

Yes, Positive and Neutral to the light switch. there are then 4 positive switches coming out (i.e. positive) the positive goes to the relay to turn on. There is one negative feeding the relays, Turning the relay on and off allows the 12volt supply to flow through.

[@mikeycbd]

Hi, I can't see anything in the app. Not like the smart sockets.

[@krieg_guardsman9548]

Can you dim the lights with the app?

[@mikeycbd]

No.
