### ⭐⭐⭐⭐⭐ Excellent remote switch
*by P***E on 24 June 2024*

Purchased to enable switching of power to cameras inside a boat which has a MiFi that it connects through - works flawlessly and can be scheduled via the Tuya Smart app and is very flexible in how you want it to operate. When it is on a red led lights up inside the unit that is not too bright but indicates its state of operation.
