Hello,  
I’ve a quick question, maybe an obvious one.  
I’m adding some lights to a lego I’ve built. They are gonna ship the lights with a power bank which will be inside the lego and power up all the LEDs.  
My question is: is there a product from sonoff that can be used to make the whole system working with google assistant? I only need to be able to turn it on and off. Thank you in advance

You may need a relay with dry points, give it a search and you may find solutions

Something like this would do the trick.

Sorr for the misunderstanding, it should be **Relay with Dry Contacts**
